Western Animation: Gravity Falls

Just north of normal, just west of weird.

"Unfortunately, my suspicions have been confirmed. I'm being watched. I must hide this book before He finds it."

"Remember—in Gravity Falls, there is no one you can trust."

Gravity Falls is an animated Disney Channel Original Series created by Alex Hirsch and produced by Rob Renzetti. It began airing on June 29, 2012.

The show tells the story of twins Dipper and Mabel Pines, who have been sent to live for the summer with their "grunkle" note  Stanford "Stan" Pines in the valley town of Gravity Falls, Oregon, where he owns the Mystery Shack, "the world's most bizarre museum". Dipper and Mabel's situation worsens (or, rather, betters) when Dipper finds a mysterious book, whose cover is only marked with the number "3" and a hand with six fingers. Upon opening it, Dipper finds a Great Big Book of Everything explaining the many strange beings, past events, and even federal cover-ups that exist within this town of secrecy — all cut through with an urgent warning: Trust No One! Thus begins Mabel and Dipper's adventures as they interact with the supernatural world that surrounds them.

After the first season finale, Alex Hirsch announced that the series would be going on a possibly year-long hiatus. Several Miniseries were released over the break to keep fans satisfied. Such miniseries include:

Season 2 premiered on August 1, 2014, 364 days after the season 1 finale. New episodes now premiere on Disney XD first and then appear on Disney Channel later on.

The show has pages for recaps and Shout Outs, plus a Best Episode Crowner. Be sure to check out the analysis and characters pages.


This show contains examples of the following tropes:

    open/close all folders 

    A - E 
  • Abhorrent Admirer: Li'l Gideon. Well, it was funny up until he went crazy and tried to stab Dipper.
  • Abusive Parents: Pacifica's parents treat her like a trained dog. No, seriously .
  • Accidental Hug: Pacifica gives one to Dipper when she gets a little caught up in the moment.
  • Action Girls:
    • Mabel, Grenda, and Candy have all displayed Action Girl traits.
    • Wendy proves herself beyond a shadow of a doubt as one of these in "Into the Bunker."
    • Pacifica proves capable in "The Golf War."
  • Adjective Noun Fred:
    • The Japanese dub of the show, Kaiki Zone Gravity Falls.note 
    • The Japanese title of "The Hand That Rocks the Mabel" is "Chōnōryoku Shōnen Gideon".note 
  • Adorably Precocious Child: Dipper, but make sure not to tell him you think so.
  • Adorkable:
    • Mabel and Dipper.
    • Candy and Grenda.
    • Soos.
    • Pacifica, of all people, as her Character Development sets in.
  • Adult Fear:
    • "Tourist Trapped" contains a quite plausible child-abduction scenario.
    • "Gideon Rises" has a subtle but very painful one: Stan is forced to realize that, having lost the Shack, he cannot take care of Dipper and Mabel. This is evident when we see him talking with Dipper and Mabel's parents; he lies to them about their current condition and we see him realize that they cannot live with Soos for the summer since there is little income and little food. This strikes a chord for many parents or guardians who fear they may have to surrender their kids to other family members or social services because they can no longer take care of them.
    • Much of the Dipper/Wendy arc counts for people who have anxiety and shyness towards dealing with romance. The fear of romantic rejection gets more or less thrown in during "Into the Bunker" where Dipper decides it's not worth it to admit his feelings for her, but ends up doing it anyway; and, while flattered, Wendy turns him down due to the age gap between them. Similar anxiety is displayed in "Soos and the Real Girl."
    • Considering how ridiculous and cartoony the plot ends up becoming, the central conflict of the episode "Fight Fighters" is surprisingly mundane and relatable: Dipper is being pressured into fighting somebody much bigger than he is, and while he doesn't want to run away like a wimp, he's also very, very scared of being hurt. There's a few lines suggesting he's afraid of being killed.
    • In "Blendin's Game", while "fear" may be a strong word in this case, Soos's deadbeat father is portrayed very realistically. And it's not just Soos who is affected; his Abuelita has to raise him herself and is shown having difficulty helping him understand, and Dipper and Mabel simply have no idea what to do.
    Dipper: We promised Soos a happy birthday, but how can we give him that now? This goes beyond anything we know how to fix.
    • Played for Laughs in "Boss Mabel": looking into the eyes of a gremloblin will force you to experience your worst fear. What does the gremloblin see when it looks into a mirror? Himself saying "You've become your father!"
    • Decidedly not Played for Laughs in "Not What He Seems." Dipper and Mabel go to child services. (Well, they would have if they hadn't slipped away.) That's terrifying to kids and adults.
    • Throughout the first season, it's revealed that Stan has been attempting (and failing badly) to hide the nature of the town from Dipper and Mabel because he recognizes that they're in real danger if they pry too far. The events that happen throughout the show, particularly in the second season, prove him to be very right.
  • Adults Are Useless:
    • Grunkle Stan, particularly in "Tourist Trapped". There are times, however, when he manages to avert it like when he punches a pterodactyl. Subverted in "Scaryoke" when it turns out he'd been lying about his knowledge of the supernatural to try to keep Dipper and Mabel away from it.
    • Downplayed with Soos, who's usually ready to lend a hand in monster hunts.
    • Sheriff Blubs and and Deputy Durland combine this with Police Are Useless.
  • Advertised Extra: When the show first came out, many of the promos featured Norman. He turned out to be a bunch of gnomes in disguise. They weren't seen again until the first season's finale.
  • Aerith and Bob:
    • The gnomes are named Jeff, Carson, Jason, Steve, and Shmebulock.
    • The manotaurs names include Testosteuror, Glurk, Pituitor, and Beardy.
  • Aesop: Every episode of the show has at least one, and they're woven relatively subtly into the narratives to boot.
    • "Tourist Trapped": Do not go into the woods alone with a guy you just met.
      • Also, even when you're stuck in an unfamiliar or undesirable place - such as a decaying Oregonian tourist trap - still try to make the best of your circumstances.
    • "The Legend of the Gobblewonker": Spend some time with your elders - they'll appreciate it and you might have more fun that you assume.
    • "Headhunters": Don't let others tell you you're not good enough to do something.
    • "The Hand that Rocks the Mabel": If you're feeling uncomfortable about where a relationship is going, it's okay to set boundaries and say "no". And the more someone lavishes attention and expensive gifts on you to pressure you into playing a certain role for them, the warier of them you should be.
      • Also, you should be the one to confront the problem instead of someone else, as they could end up as collateral damage.
    • "The Inconveniencing": Sometimes, what sounds really cool in theory isn't that much fun when you actually try it, particularly when it's just done as an attempt to impress others.
    • "Dipper vs. Manliness": Even if nobody backs you up, don't be afraid to do what's right.
      • Alternatively, you are as manly as you think you are and do not be discouraged if others say otherwise. (Alternatively, alternatively: "true" manliness - or girliness - isn't always what society thinks it is, and you shouldn't be afraid to express yourself in a unique way.)
    • "Double Dipper": If you like someone and want to ask them out, don't be afraid to just talk to them about it.
      • Alternatively, your real friends will stick by you no matter what happens.
    • "Irrational Treasure": Don't dismiss someone's abilities just because you don't think they're important or useful.
      • Alternatively, while there are people who are content enough with self-assurance, there are also others who need to get back at those who wronged them, and either approach is fine.
      • you are are unique the way you are and you shouldn't change any part of that for approval (especially from someone who already hates you) otherwise you will lose what you already have.
    • "The Time Traveller's Pig": You can't have everything you want all of the time.
      • Alternatively, taking what you want can end up with you taking what someone else wants just as much. (Works both ways, since Mabel abandoned her chance to help Dipper in order to win Waddles.)
    • "Fight Fighters": Face things you don't like or are afraid of with grace rather than trying to run away, but Know When to Fold 'Em when you surpass your abilities.
    • "Little Dipper": Don't destroy something just because you personally don't need it anymore. Also, don't let your insecurities blind you to your accomplishments.
    • "Summerween": If someone is threatening you, make sure you tell someone and not just keep it to yourself.
      • Also, it's okay to do childish things, even as you get older.
    • "Boss Mabel": Settle for what you have already as opposed to unwisely taking a gamble on it all.
      • Alternatively, sometimes you have to be tough to get something to work, and must be understanding when you're on the receiving end of that toughness
    • "Bottomless Pit": Three.
      • Voice Over - Your personal qualities might not be perfect, but they're yours.
      • Soos' Really Great Pinball Story - Don't cheat, and don't be selfish.
      • Trooth Ache - Sometimes, you have to tell a little white lie to spare the feelings of others.
    • "The Deep End": Don't do something without thinking it through. It can lead to doing something needlessly that you will regret.
    • "Carpet Diem": Don't make important decisions when angry.
      • Secondly, don't pretend to be someone else and try to hurt their reputation.
      • Thirdly, don't ignore your old friend's feelings just because you made some new ones.
    • "Boyz Crazy": Don't arrive late for something and be surprised when they've run out of what you want. Alternatively, you should help someone for the sake of making them happy, not for personal gain.
    • "Land Before Swine": Lying about something, then trying to perpetuate the lie even though you or someone else might get hurt, is a bad idea.
      • Alternatively, stay away from hungry, meat-eating animals that are bigger than you. (Bit of a no-brainer.)
    • "Dreamscaperers": Don't sabotage your master plan to help your disguise you made to help with said master plan.
      • Alternatively, let people finish speaking before judging what they say.
    • "Gideon Rises": Just because you're not the strongest or the smartest doesn't mean you can't be the hero.
      • Secondly, just because something has had no use in the past doesn't mean it won't in the future.
      • Thirdly, if you believe something you are looking for is somewhere on a specific property, check every nook and cranny inside before you start digging outside.
      • Fourthly, sometimes people, including the police, get to pick and choose who to believe based on their own preferences, and they are jerks for doing it.
    • "Scaryoke": Don't let your ambitions blind you to the potential consequences of your actions.
      • Also, remember the important matters like spending time with family.
    • "Into The Bunker": If you like someone and it's eating you up with anxiety, sometimes you have to take a risk and say it, because uncertainity is often worse than certainity.
      • Also, sometimes people need a push, but you still have to respect their choices in the end.
    • "The Golf War": Grudges and rivalry will only lead to misery, and the only way to truly end them is to be the bigger person and turn the other cheek.
      • Secondly, don't get involved in other peoples disputes, or let others get involved in yours.
      • Thirdly, playing one side against the other for your own gain isn't only deceitful, it's dangerous.
    • "Sock Opera": Don't take for granted the people that care about you for your ambitions. If they're willing to give up everything, you should do the same.
      • Also, don't go blindly chasing after someone until you know them a bit better, since failing to be with them might be dodging a bullet.
      • Thirdly, DON'T MAKE DEALS WITH DEMONS or similarly styled energy beings.
      • Fourthly, no matter how important something is, foregoing sleep is never a good idea; if anything, it'll make things worse.
    • "Soos and the Real Girl": Don't be afraid to go out into dating; while dating sims can seem like a good substitute, they fail because they have no depth to them.
      • Envy is never any good and can cause more trouble than its worth.
      • Also, a life of unpredictability (especially regarding relationships) is worth way more than the predictable.
      • Just be yourself; there are billions of fish in the sea, and at least one is bound to like you just the way you are.
    • "Little Gift Shop of Horror": BUY SOMETHING FROM THE MYSTERY SHACK IF YOU KNOW WHAT'S GOOD FOR YOU.
      • The episode in general parodies this theme with several Family Unfriendly Aesops. However, each segment does contain a secondary actual aesop as well.
      • Hands Off: The only reason witches curse people or inconvenience them is because they're lonely. Also, don't steal. Just don't.
      • Abaconings: Don't bother using your newfound intelligence to make yourself famous, help make the world a better place, or gain powerful allies like world leaders and scientists. Instead, you should throw all of this away to live a life of ignorance with a little scatterbrained girl who enjoys making fart noises with her keyboard, simply because you consider her your "best friend". Also, pursue science for the sake of discovery, not glory.
      • Clay Day: Stop-motion is not only terrifying, but (due to being created by black magic) is actually unholy. Why do you think many stop-motion animated films revolve around such dark themes? Also, if you may not conquer your fears, face them anyway if your loved ones may get hurt from it.
    • "Society Of The Blind Eye": When confronted with uncomfortable, disturbing or even frightening truths, it is better to confront them and learn from the experiences than to forget, otherwise the consequences may hurt you and or others. So true if people watched the credits, as McGucket starts to remember who wrote the journals.
      • Driving this point home, it's worth pointing out that the members of said Society that have character development beyond "One-off gag" (i.e the woodpecker marriage guy) aren't dealing with their pain, just making themselves forget and experiencing the same hurt over and over again. And it's also shown that this is an incredibly unhealthy way to deal with your emotions. Toby is implied to have joined and used it to deal with his Hopeless Suitor tendencies towards Shandra Jimenez, and because he's not dealing with them, he experiences the same pain of rejection near constantly and doesn't move on. Bud Gleeful also joined to forget about his Enfant Terrible son, and so he's stuck dealing with the same stuff over and over, and Blind Ivan just uses it to erase any guilt he might have over issues like McGucket's memories, which has disturbing implications.
    • "Blendin's Game": Your family is made up of the people who love and care about you, not necessarily the people you share blood with.
      • Also, if somebody truly doesn't care about you, don't get hung up over them. Even if they're a parent, if they don't think you're worth their time, they're not worth yours.
      • Thirdly, even if someone tried to ruin your life for what you did to them, you should forgive them and do something nice for them. It might turn their life in a brand new direction.
    • "The Love God": If somebody you know is in a happy relationship that you're not necessarily comfortable with, the best thing to do is take the selfless route and be happy for them.
      • Also, everybody deserves compassion, even people who haven't necessarily shown it to you. Even if somebody's a jerk, they still have feelings, and often showing them kindness is the best way for them to start growing into better people.
      • Also, it's not right to play with peoples lives without their consent, even if you have the best of intentions.
    • "Northwest Mansion Noir/Mystery": Just because you come from a family with a long history of being vile individuals doesn't mean you have to follow in their footsteps.
      • Also, don't judge a person by their cover. Chances are, when you get to know them, they're more complex and interesting than you thought they were.
      • And finally always keep a promise and never betray your friends for personal gain because you might loose more than what you wanted.
    • "Not What He Seems"
      • Don't assume the worst. Doing so will only cause more unnecessary grief.
      • If you have a secret that needs to be said to your loved ones, say it before it too late.
  • Affably Evil:
    • The ghosts from "The Inconveniencing" would be just like any other sweet old couple... except they entrap and torment any teenager that comes into their store.
    • Zombie!Soos, who combines the ruthless killing instinct of the undead with the cheerful personality of... well, Soos. "Sorry, dude, but I just really want those brains!".
    • Jeff, the leader of the gnomes, and the only one with a major speaking role. He has a very easy-going and helpful attitude, and would be a perfectly nice guy were it not for the insignificant little fact that he wants a twelve-year-old to marry him and all his gnome brethren and isn't taking no for an answer. He also seems suspiciously inclined to cannibalism.
  • Affectionate Gesture to the Head: Stan's preferred form is affectionate noogie-ing.
  • Affectionate Parody: Of bizarre-small-town mystery series like Twin Peaks and Northern Exposure.
  • Agent Mulder: Dipper and Soos, the former spurred on by a supernatural compendium. For example, in "Tourist Trapped", Soos says the mailman's a werewolf and believes Dipper's theory about Mabel's boyfriend being a zombie, a theory Dipper came up with after looking though the book.
  • A.I. Is a Crapshoot: Giffany, although there's probably some other supernatural forces at play.
  • Air-Vent Passageway:
    • Dipper uses one to get into the convenience store in "The Inconveniencing".
    • The wax head of Larry King used the Mystery Shack's air ducts to make his escape. Apparently, "He's still in the vents."
  • Alien Blood: Used on a few occasions in the second season, first with the zombies in "Scary-oke", and then with the shape shifter in "Into the Bunker". Both bleed green blood, which is likely the only reason why the pretty significant amounts of violence against them were allowed on the Disney Channel in the first place.
  • All Myths Are True
  • All There in the Manual:
    • Lots of info on characters, secret codes, screenshots and animated GIFs of 4 and beyond, as well as information taken from online games and otherwise, were being thrust into the public's hands before most folks could barely watch Episode 2.
    • Dipper's book serves an in-series example, seeing as it has information on all the creatures, various spells, and even a clue to a conspiracy.
  • Alliterative Name: Gideon Gleeful, Blendin Blandin, and Nathaniel Northwest.
  • All Women Are Lustful: A (probably) non-sexual example, but Mabel and her friends (Mabel in particular) are very, very obsessed with boys. Exaggerated in the aptly titled "Boyz Crazy", where she starts huffing and puffing like an addict when her "Pet boy band" is being taken away from her.
  • A Load of Bull: The manotaurs.
  • Alpha Bitch: Pacifica Northwest.
    • She does get better in the end of The Golf War, but whether or not she remains that way is yet to be seen.
    • Lovable Alpha Bitch: Season two is steering her character towards this.
  • Always Identical Twins: Averted by Dipper and Mabel themselves but toyed with for Stan and his twin brother, The Author. They look very similar physically except his brother has six fingers on each hand. It's unknown if this was always the case or if he attained said extra fingers later in life, messing around with the super natural.
  • Always Someone Better: In "Little Dipper", Mabel vents her frustration that Dipper seems to always beat her at everything.
  • Amazingly Embarrassing Parents: Mabel decides to talk about Dipper's "Lamby Dance" at the very worst possible time...
  • Ambiguously Bi:
    • Soos starting late in season 1 and carrying through to season 2. While unambiguously attracted to women, he notes how attractive Stan was in his younger days in "Dreamscaperers," states that he wouldn't mind if Stan kissed him in "Scary-oke," and in "The Golf War" he makes note of the stars while staring and lying back with Stan in the car at night.
    • Made even more ambiguous when you consider that Soos implied in "Dreamscaperers" that he wishes Stan would love him like a son.
  • Ambiguously Brown: Nate and Tambry, two of Wendy's friends.
    • Soos was this for a number of episodes, until "Gideon Rises" finally confirmed he was Hispanic.
  • Ambiguously Evil: Stan, all the frigging time. It only gets even more ambiguous in "Gideon Rises" where his underground lab is finally shown.
    • As of season 2, he's zigzagging this all over the place. It's unquestioned that he genuinely cares about the twins, but at the same time, he stole Dipper's journal and has the thing going on behind the vending machine, for which his use of the term "get caught" implies less-than-noble intent.
      • In the end, he was trying to bring his brother back. Not lawful thing to do and it was REALLY risky, but he had good intentions
  • Ambiguously Gay: Tyler, the Cute Biker. He shows up out of nowhere to cheer on Manly Dan beating up a fish. He also shows up in the restaurant where Mabel and Gideon go on a date, calling the two adorable. His shorts are... pretty short, and he has visible eyelashes, which otherwise only female characters have. Also, in "Irrational Treasure" he and Manly Dan are briefly seen sharing a plate of meat between themselves. In "Boyz Crazy" he, along with Old Man McGucket, are in the audience at the Sev'ral Timez concert.
    • Sheriff Blubs and and Deputy Durland act very much like a married couple most of the time. Blubs' pronunciation of "Durland" sounds suspiciously like "darlin'".
  • Ambiguously Jewish: The Pines family. Mabel and Grunkle Stan occasionally use Yiddish words ("mazel tov", anyone?), and Mabel herself has been known to put "Moses" where others would use "Jesus Christ". Dipper and Stan fit a couple of stereotypes respectively. there's also the fact that "Pines" is an eastern Ashkenazi Jewish surname. However, despite Alex Hirsch's Judaic background and the fact that he based the Pines on himself and his family, he has confirmed that the Pines family is not Jewish. This happened after artists would get told by fans that it's offensive of them to draw the twins celebrating Christmas. In another tweet, he proceeded to draw the twins wearing Santa hats, himself.
    • Another set of tweets clarifies that while Alex personally sees the Pines twins to be like himself and his own sister (ethnically half Jewish and celebrating both Christmas and Hanukkah ), he encourages the fans to imagine/interpret them how they like.
  • Amnesiac Dissonance: Old Man McGucket founded the Society of the Blind Eye.
  • Amusing Injuries: All over the place. Lampshaded by Bill during his time in Dipper's body.
    Bill: Pain is hilarious! (Rams arm into a drawer)
  • An Axe to Grind: The wax sculptures.
    • Wendy during "Into the Bunker," with Dipper taking a turn while Wendy is occupied with Experiment 210.
    • The Lumberjack Ghost in "Northwest Mansion Noir/Mystery".
  • And I Must Scream: With the exception of Pacifica and her parents, the entire party in "Northwest Mansion Noir/Mystery" is turned into wooden sculptures, in what the Lumberjack's Ghost terms a "Forest of Fear"
  • And Now You Must Marry Me: The gnomes after they kidnap Mabel.
  • And This Is for...
    Mabel: "That's for lying to me! That's for breaking my heart! And this is for messing with my brother!"
  • And Then John Was a Zombie: Soos is transformed into a zombie in "Scary-oke" after Dipper accidentally awakens the dead. Thankfully, his book came with a cure.
  • Anguished Declaration of Love: In "Into the Bunker", Dipper finally confesses his feelings to Wendy in a fit of grief as he tries to awaken her seemingly-dead body. Fortunately, it wasn't actually her, and she was standing right behind him the whole time.
  • Animated Series
  • Animation Bump: While the show itself looks pretty good, the entire intro is drawn with more detailed shading and fuller animation. More evident are Mabel plugging her sweater into the outlet and Dipper getting scared and dropping his candle.
    • Those last two shots were animated by renaissance-era Disney animator James Baxter.
    • The sea monster in "Legend of the Gobblewonker" is particularly nice.
    • Rumble in "Fight Fighters", due to being animated entirely by Paul Robertson.
      • Robertson's sprites get even more complex in "Soos and the Real Girl"; justified in-story, as the dating sim Romance Academy 7 has much more processing power than an arcade game from the 1980's.
    • The animation during the climax of "Not What He Seems" is gorgeous.
  • Animesque: Giffany in "Soos and The Real Girl", as she's from a Japanese Dating Simulation game called Romance Academy 7.
  • Annoying Younger Sibling: Being twins both Mabel and Dipper are sometimes like this toward each other, though they're still the best of friends.
  • Anti-Mutiny: What the clone Dippers try to do to Dipper in "Double Dipper". When Tyrone realizes that the original plan wasn't working, they laugh it off and share a soda instead.
  • Apocalyptic Log: Dipper reads the page quote in Journal #3 about that the author needing to hide the book away before it trails off.
    • In the Season 2 episode "Society of the Blind Eye", the main cast and Old Man McGucket find that the Society of the Blind Eye uses a device to remove memories of paranormal activity. They recover Old Man McGucket's memories of inventing the device from the Society, and watch them depicting his descent into insanity by repeatedly wiping his own memories.
  • Arbitrary Skepticism: In "Bottomless Pit!", Grunkle Stan still states that everyone's stories are far-fetched, even though he is falling through a bottomless pit even as he speaks, and even lived through one of the stories.
    • Also present in "The Land Before Swine", when Grunkle Stan refuses to accept magic, but is totally okay with dinosaurs alive in the summer of 2012 specifically because they aren't magical. Ultimately subverted in the first episode of season two, when Stan declares that he's "not stupid" and was just trying to pretend that none of the supernatural events in the series were happening to keep Dipper away from it all.
  • Arc Number: "6:18" appear in many episodes, as June 18th is the creator's birthday.
    • "30 years" is starting to get thrown around in Season 2; in "Scary-oke," Stan mentions that it's how long he's been working on the portal beneath the shack, as well as the agents mentioning that they haven't seen readings like the ones given off by said portal in 30 years; in "Into the Bunker," Experiment 210 says that the author of the journals "hasn't been himself for 30 years," and the map of Gravity Falls that Wendy removes to reveal the door to the author's lab is dated circa 1982- 30 years prior to the 2012 when the series seems to take place. In an example from the first season, the calendar hanging in the hidden room in Carpet Diem was also dated 1982. If that wasn't enough, even Old Man Mc Gucket claims that, prior to "Society of the Blind Eye," the earliest he could remember was around 1982—immediately after creating the Society, wiping his memories, and the completion of the portal...
    • "3" seems to be the primary contender for the show's Arc Number. A projected three-season arc, three journals, three seasons on summer, three sides and points on a triangle, 30 years is three rounds of ten...
  • Arc Symbol: A simple drawing of an eyed pyramid with limbs and a top hat is all over the series, from the opening credits to the Mystery Shack's windows. He turns out to be an extremely powerful demon named Bill Cipher.
  • Arson, Murder, and Jaywalking: The Mystery Shack crew discusses their past encounters with Gideon Gleeful:
    Mabel: Remember when I wouldn't date him and he tried to destroy us?
    Stan: He's always trying to trick me into losing the Mystery Shack.
    Wendy: One time I caught him stealing my moisturizer.
  • Armour Piercing Question: Agent Trigger gives this to Dipper causing him to question the events of the episode Not What He Seems.
  • Art Shift:
    • In "Fight Fighters", the video game is shown pixelated.
    • Giffany in "Soos and the Real Girl".
    • Mabel's Imagine Spot in "Legend of the Gobblewonker."
      • Funnily enough, in "Dreamscaperers," Bill Cipher causes the cute teenage boys from Mabel's Imagine Spot to appear in Stan's mind, retaining their style while interacting with the normally-drawn environment.
  • Art Evolution: It's subtle, but the animation quality does improve between seasons one and two.
  • As Himself: In "Headhunters", both of the Coolio and Larry King wax figures are actually voiced by the real Coolio and Larry King.
  • Asian and Nerdy: Candy Chiu.
  • Attention Deficit... Ooh, Shiny!: Soos 100% of the time and Mabel most of the time. Actually saves Soos' life in "Skary-oke"
    Mabel "Don't worry, brother. Whatever happens I'll be right here, supporting you every step of the— oh my gosh a pig!"
  • Author Avatar: A few. Alex Hirsch voices a number of characters on the show, and many of them are very, very important. Examples include Stan, and Bill Cipher.
  • Auto-Tune: Utilized at all times by Boy Band Sev'ral Timez in "Boyz Crazy".
  • A Wizard Did It: Mabel believes a wizard hiding in the closet is behind Dipper's sudden growth spurt in "Little Dipper".
  • Awesome McCoolname: Dipper #2 decides on "Tyrone".
    • Fiddleford Hadron McGucket
  • Awkward Father-Son Bonding Activity: Grunkle Stan taking Dipper and Mabel fishing.
  • Ax-Crazy:
  • Back-to-Back Badasses: Mabel and Pacifica team up this way against the Lilliputtians.
  • Badass Adorable: Dipper and Mabel.
  • Badass Bookworm: Dipper is very rational, observant, and is the go-to guy for information about Gravity Falls. He also gradually gets more and more badass as the series goes on, shown off best during his No-Holds-Barred Beatdown with Gideon in "Gideon Rises".
  • Badass Family: All the members of the Pines family shown up to date fit some form of Badass or other.
  • Badass Grandpa: Grunkle Stan, shown best so far in "The Land Before Swine" and "Scary-oke."
  • Bad Boss: Stan.
  • Bad Future: Apparently, in the future, a time baby will destroy everything and take over humanity. On the plus side, humanity gets time travel.
  • Bad-Guy Bar: The twins use fake IDs to enter one in "Headhunters."
  • The Bad Guy Wins: The end of "Dreamscaperers". Gideon manages to collect Stan's deed to the Mystery Shack and has his father blow the roof off.
  • Balloon Belly: Mabel gets one after eating too much Smile Dip.
  • Bare Your Midriff: Wendy wears an ensemble of this type to the Wood Stick Festival in "The Love God".
  • The Barnum: Grunkle Stan.
  • Bathos: The Big Henry scene in "Golf War". It'd be incredibly sad and jarring (and some people found it that way anyway), were it not for the fact that it takes place right under the noses of completely oblivious golfers and involves little people with golf balls for heads.
  • Batman Gambit: Done by Mabel in "Tourist Trapped."
  • Behind the Black: In Dippers Guide to The Unexplained #82, there were several points where people, including Dipper, could have that the man was a robot that had no right side.
  • Beneath the Mask: Quite a number of characters.
    • Wendy isn't actually as laid-back and cool as she lets on; underneath, she's almost constantly stressed out.
    • Robbie acts like an apathetic Jerk Ass to virtually everybody, but secretly he's very awkward, lonely, and insecure.
    • Pacifica appears to be a quintessential Rich Bitch, but she's also a Lonely Rich Kid who doesn't appear to be loved by anyone, not even her own parents.
    • Even our own Dipper is a mild case; in "Society of the Blind Eye" he revealed that he's playing up the cooler and smarter parts of his personality on purpose in order to hide crippling pre-pubescent insecurity.
  • Benevolent Boss: Mabel starts out as one when she takes over for Stan in "Boss Mabel". It doesn't last.
  • Berserk Button: Do NOT call Dipper a wimp, or a baby, or not a man, or kid. Point is, he hates being a wimpy 12 year old and hates it even more if you comment on it.
  • The Bet: Stan and Mabel make a bet on who could make more money: Mabel while running the Mystery Shack, or Stan while on vacation.
  • Better as Friends: After Dipper's confession to Wendy, she confesses to having suspected it and while very flattered, she pretty much says this.
  • Better Than a Bare Bulb
  • Beware the Honest Ones: Stan in "Bottomless Pit".
  • Beware the Nice Ones: Dipper and Mabel.
  • Beware the Silly Ones:
    • Old Man McGucket has proven himself capable of quite a bit of destruction.
    • Mabel, despite being a total Cloud Cuckoo Lander, has been shown to be perfectly competent both in physical combat and helping solve mysteries with her brother.
    • Bill Cipher. Don't let his laid-back sense of humor and strange design fool you; he's every bit as dangerous as his reputation would suggest.
    • Soos, such as in "Soos and the Real Girl" and "Not What He Seems."
  • Beyond the Impossible /Alien Geometries: Several scenes in the episode "Fight Fighters", as well as the entire minisode "Lefty", could not take place in a 3D universe, and suggest that Gravity Falls's universe is 2D.
  • Big Bad: "Li'l" Gideon Gleeful, at least for Season 1.
    • In Season 2, Bill Cipher is shaping up to be one, given his big role in Sock Opera and the tapestry in the Northwest Mansion implies that he's planning on bringing upon the apocalypse.
  • Bigger Bad: Bill Cipher is and always has been the greatest threat of all.
  • Big Brother Instinct: Dipper constantly, constantly watches out for his sister's well being and safety. He doesn't smother her or anything, but whenever the two of them encounter danger, her safety is always his number one priority. This tumblr post really sums it up best.
    • And even in less dire moments, like when she needs emotional or moral support, he's always there to lend her a hand and will stop at nothing until she feels better. For example, in "The Land Before Swine", when Dipper finds out that the pterodactyl took Waddles, he is dead-set on helping his sister get her beloved pet back.
    • Mabel also has had several instances of Big Sister Instinct. In fact, her brother being threatened or hurt is one of the few things that manage to bring out her more serious side. For the record, Mabel is older by five minutes.
    • Soos also seems to have a bit of this for the twins, despite not being an actual relative.
  • The Big Damn Kiss: Between Mabel and Mermando.
  • Big Eater: Whenever Soos isn't helping the twins or working on the Mystery Shack, he tends to stuff his face.
  • Big Fun: Soos is a big, funny Man Child whose great friends with the kids.
  • Big "NO!": There are three in a row in "Carpet Diem": on from Mabel, one from Dipper, and one from Soos.
  • Big Screwed-Up Family:
    • While not exactly "big", Gideon's relationship with his parents is very, very, very messed up.
    • The Northwest family, going back to Nathaniel has been a decades-long line of classist swindlers. Preston Northwest controls his own daughter through Pavlov-style conditioning, and encourages her to act like a brat. Pacifica, however, appears to be growing out of this.
  • Big Stupid Doodoo Head: Mabel calls the gnomes butt-faces. In fact, if Mabel insults someone, it'll usually be this trope.
  • Bilingual Bonus: The spell Dipper does in "Dreamscaperers" is part actual Latin and part Canis Latinicus joke, and it can be roughly translated to: "See everything, Master the Mind! Magnesium to man! Masterpiece! May you have your body! Inceptus Nolan Overratus! Master the Mind, Master The Mind, Master The Miiiiiiiind!"
    • The spell Gideon uses (also in Latin) to release Bill Cipher, however, makes much more sense in English: "Triangle, I invoke you! I come to the defensive barrier of the mind! I will see the barrier destroyed!"
  • Birds of a Feather: Soos and Melody, who seem to be officially dating by the end of "Soos and the Real Girl.
    • Robbie and Tambry, both gloomy and apathetic Emo Teens start dating in "The Love God".
  • Bitch in Sheep's Clothing: Li'l Gideon.
  • Bittersweet Ending: Few episodes have these like "The Time Traveler's Pig," "Boyz Crazy," and "Into the Bunker." Interesting trend is that the main focus or the B-plot is on Wendy and Dipper's relationship.
  • Black Comedy: Oh, you'd be surprised. The number of times death is referenced for comedy in this show is quite astounding for a bright and cuddly-looking Disney show, sometimes boosting it up to murder and suicide when it wants to. Once season two came around, it became almost a guarantee that it will happen at least once an episode.
  • Black Comedy Burst: Despite how consistently dark the show's comedy is, one moment definitely stands out among the rest: in the "Lefty" short from "Dipper's Guide to the Unexplained", the twins investigate a man who seems to only ever show his left side. And the end, it's revealed that this is because he's actually a robot with his right half completely gone, and he's being operated by a bunch of small amoeba-like creatures. Upon realizing that their cover has been blown, they all immediately commit mass suicide on camera by shoving green pills down their throats. One of them even protests by saying that he has a family, causing one of his comrads to tell him "You signed the oath!" and then shove the pill in for him. All of this was most likely Played for Laughs.
  • Black Gal on White Guy Drama: Played with in "The Love God". Robbie and Tambry end up together, and the drama coming from Wendy's friends stems not from racial or social issues, but from long-seated emotions towards everyone else. At the end, the group is back together, and the interracial aspects aren't even brought up.
  • Bland-Name Product: "Pitt" brand soda, possibly a parody of the real-life brand "Mr. Pibb". It's been sighted on a machine inside the haunted convenience store, and Dipper and Tyrone drink it at the end of "Double Dipper".
    • Or, more likely, "Cott". Cott's is also almost immediately associated with orange-flavored pop, and what's the logo seen on a Pitt vending machine?
      • It's a peach. Pitt Cola is shown in almost every episode, and the Gravity Falls site say it's a peach flavored cola with an actual pit inside the can.
      • Fun fact: The soda is very probably named after the show director Joe Pitt, whose name you can find in the credits.
  • "Blind Idiot" Translation: In-universe, all the dialogue of Rumble McSkirmish and the "Fight Fighters" game. This is also played for laughs in "Soos and the Real Girl." The videogame Soos plays to learn how to interact with real women is the English translation of a game that was originally released in Japanese. It contains lines like:"Anthyding can Hadplen."
  • Blondes Are Evil: Pacifica Northwest. Subverted in season 2, where we find out she was being trained to act like this by her parents.
  • Blood-Stained Letter: The page in a mystical journal on how to summon the demon Bill Cipher is covered in blood, with the words "Do not summon at all costs" written directly in blood.
  • Blue and Orange Morality: Rumble McSkirmish spends most of his time running around town and destroying everything in sight with his bare hands. It sounds sick until you remember that he's a character in a fighting game come to life.
    • Bill Cipher is showing signs of this, though it's still hard to say.
  • Blush Sticker: Mabel and her friend Candy have permanent circles of pink on their cheeks.
  • Body Horror: Some surprisingly intense examples of this, particularly in season 2.
  • Bookcase Passage: Shown in "Tourist Trapped". Stan has a passage hidden behind his vending machine. Where does it lead to? An underground research facility, where Stan has been holding Book #1 for years and has been waiting for Book #2 (retrieved after Gideon was arrested) and Book #3 (took it from Dipper when Dipper showed it to him). He needed them to summon something. What is it? No one knows... until season 2 premieres.
  • Book Ends: The ending of "Tourist Trapped" (the pilot) shows Stan entering his secret vending machine passage, and the ending of "Gideon Rises" (the season one finale) shows Stan entering his secret vending machine passage... revealing that he's been hunting the books for a while, and needs them to summon an ultimate power.
    • Both episodes also climax with the twins being pursued by a villain piloting a larger version of themselves.
  • Bottomless Pits: Featured, of course, in "Bottomless Pit".
  • Bowdlerise: In "Into The Bunker", when Dipper and Wendy were caught in a "closet", Dipper and Wendy bumped into each other at one point after Wendy pulled a handle. However, in the original storyboard work, Dipper was going to stay with his face in her chest for a while, then pushing her away in desperate attempt to get out, embarrassed, fearing she would be mad at him. And of course, this being Disney Channel and an Y7-rated show, it was scrapped.
  • Bowties Are Cool: In addition to the bowtie in Stan's regular ensemble, Quentin Trembley wears one, and Dipper and Wendy both don them in "Double Dipper".
    • Bill Cipher wears a bowtie, and it is very cool. It can turn into a tv screen!
  • Boy Band: Sev'ral Timez, an affectionate lampoon of 90's boy bands.
  • Brain in a Jar: The Mystery Shack has two, dressed in wigs. Apparently, one's a man and one's a woman.
  • Brainless Beauty: The beautiful but absolutely clueless members of Sev'ral Timez.
  • Brains and Brawn: It's subtly portrayed, but Dipper is more inclined to planning and reading while Mabel is more of a girl of action.
    • This trope also applies to anytime Dipper and Soos team up.
  • Brawn Hilda: Grenda. She even has a completely undisguised male voice actor.
  • Breather Episode: "The Land Before Swine", considering the episode that immediately follows.
    • "The Golf War", which comes after the plot-heavy episodes "Scaryoke" and "Into the Bunker" and precedes "Sock Opera".
    • "The Love God", as it comes after "Blendin's Game" and before "Northwest Mystery Noir", both WhamEpisodes.
  • Brick Joke: In Episode 2, there's a Cutaway Gag of Grunkle Stan and the kids forging money, and he remarks that their Benjamin Franklin looks like a woman. Several episodes later the twins find a repository of America's embarrassing secrets that includes a folder about which Mabel remarks: "Oh man, Benjamin Franklin secretly was a woman!"
    • It's also possible this was a reference to actual American history. In 1722, Benjamin Franklin, age 16, wrote several letters to the newspaper his brother James worked for under the fake alias of middle aged woman Silence Dogood. This was because James would never publish any of his works. The More You Know.
    • In "Double Dipper", Soos is the DJ for the party and needs a lightning sound effect for a punchline to one of his one-liners but can't find it on the soundboard. During the credits, we see him go over the entire soundboard and find the lightning on the very last key to which he cheerfully exclaims: "Found it!".
    • Episode 11; "Little Dipper" has Mabel rant about an "invisible wizard" in their closet as a theory on how Dipper is suddenly a millimeter taller than her. Come episode 16; "Carpet Diem" and Grenda steps out of the same closet after an obviously intense sleep over, her face covered in kiss marks, stating "I don't know what I was kissing in there, but I have no regrets!"
  • Brilliant but Lazy: Wendy has proven to be very competent in physical combat, but she only shows it if she absolutely needs to.
  • Broken Tears: Mabel, of all people, has a moment of this in "Not What He Seems". It's relatively brief, but seeing the most cheerful character on the show have a breakdown like that is a pretty good sign that things have taken a turn for the worst.
  • Brother-Sister Team: Obviously.
  • Buffy Speak: Mabel can slip into this, using phrases such as "hotty melty things" or "some kind of magicky thing."
  • Bunny-Ears Lawyer: Quentin Trembley definitely qualifies as a "Bunny-Ears (or, No Pants, rather) President."
    • Also Soos who, despite being quite peculiar and immature, is more than capable of fixing most mechanical problems and creating some genuinely impressive stuff.
  • Butt Monkey: Dipper.
    • Thompson, most definitely. It later comes to his advantage when, in a Crowning Moment of Awesome, he gets his entire friend group to stop hating each other simply by making himself the object of ridicule. They laugh so much at his 'Butt-Monkeying' that they patch up their petty arguments.
    Thompson: All according to plan.
    • Blendin Blandin, though things do eventually turn out better for him.
  • But Thou Must: Mabel pulls one on some guy with a note.
    Do you like me?
    Yes
    Definitley
    Absolutely
  • The Cake Is a Lie: Grunkle Stan attracts visitors to the re-opening of his wax museum by promising them free pizza. He then claims that this was a typo.
  • The Caligula: Quentin Trembley.
  • Caligula's Horse: Quentin Trembly appointed a group of babies into the supreme court.
  • Call Back: Crossed with Freeze-Frame Bonus, the four symbol code that Grunkle Stan types at the end of "Gideon Rises" was first seen in the first episode here
    • In essence, Blendin Blandin's flashback appearances in "The Time Traveler's Pig" function as callbacks as he does appear in every scene depicted in the end credits.
    • Mabel makes Grunkle Stan sing the "Stan Wrong Song" in "Boss Mabel." In the "Mabel's Guide to Fashion" short, we hear him sing it again, but this time willingly for some reason.
  • Calling Your Attacks: "SUPER POWER NINJA TURBO NEO ULTRA HYPER MEGA MULTI ALPHA META EXTRA UBER PREFIX COMBO!!"
    Rumble: BOWL OF PUNCH!!
    • And in a flashback of Stan's
      LEFT HOOK! *Wham!*
  • Camp Straight: Gideon's speech and mannerisms are very similar to that of a Southern Belle stereotype, not to mention he's very conscious about his looks and is often drawn with visible eyelashes. However, considering his obsession with Mabel, he's pretty clearly straight.
  • Canis Latinicus: Downplayed in "Dreamscaperers." The spell Gideon uses is actual Latin, and most of Dipper's spell is, too. However, "Inceptus Nolan Overratus!" from the latter is a case of this. (As well as a Take That at Inception.)
  • Cannot Talk to Women: Soos is hilariously inept at flirting.
  • The Chains of Commanding: "Heavy is the head that wears the fez."
  • Chair Reveal: Gideon does one in "The Hand That Rocks the Mabel".
    • Also, Mabel does one in "Boss Mabel".
  • Captain Ersatz: "Gummy Chairs" "Sand Pops" and "Mr Adequate Bar." are candies that both Mabel and Dipper are disappointed to get during summerween so they throw them out only to ultimately discover that It hated being thrown out so much that it became sentient and seeks revenge every summerween. Does it rot their teeth so they can't eat candy anymore? No. Does it force them to eat candy till the end of time? No. instead It wants to eat them alive.. Talk about Disproportionate Retribution.
  • Cerebus Syndrome: While still primarily a comedy, the show did get noticeably darker in its second season, possibly due to its Channel Hop. Even the humor became significantly more reliant on Black Comedy than it was before.
  • Cerebus Retcon: Society Of The Blind Eye implies heavily that the Cloud Cuckoo Lander tendencies of most citizens of Gravity Falls are a result of brain damage from the mind eraser gun used by the Society of the Blind Eye to make them forget the supernatural. Ouch.
    • In the same episode, it's revealed that Old Man McGucket is both the inventor of the mind eraser gun, and drove himself to insanity by using it repeatedly to forget some horrible thing he learned working with The Author.
    • The known Society members' various quirks, from Bud's cheerful obliviousness of his dysfunctional son to Toby Determined's unrequited love for Shandra Jimenez to even the carnival barker's paranoid fear of witches, suddenly become much darker in hindsight when it's learned they've all been trying to erase these sources of pain from their lives.
    • Northwest Mansion Noir/Mystery heavily implies Pacifica's parents (previously shown to be somewhat aloof and distant) to be outright emotionally abusive, including training Pacifica to respond to a bell, and that the whole Northwest family is a line of Card-Carrying Villains.
  • Cheerful Child: Mabel. Given the nature of the series, this can verge on Pollyanna status at times.
  • Chekhov's Gag: In "Into the Bunker", the Shapeshifter takes the form of a terrified Dipper as he freezes, claiming it will be his last pose before dying. When Dipper is turned into wood in "Northwest Mansion Noir", guess what pose he's doing?
  • Chekhov's Gun: The leafblower Mabel used for kissing practice is later used to fight the gnomes.
    • The grappling hook that Mabel got in the very first episode saves the twins from falling to their doom in the season one finale.
    • Stan claims that nobody ever made any money using the word "please" in "Boss Mabel". When he has a chance later to win three hundred thousand dollars on Cash Wheel, he chooses instead to go for double the money by trying (and failing) to answer one last question: "What is a six-letter word you use to ask for something politely?"note 
    • A literal gun example: In "Time Traveler's Pig", Stan rigs his dunk tank to resist any attempts to dunk him to which Soos replies it would take "some kind of futuristic laser Arm Cannon." Guess the time police hands out those as standard issue!
  • Chekhov's Gunman: Of course, Bill Cipher. He was frequently shown in the credits up until his official debut in "Dreamscaperers".
    • Early on in the episode "Soos and the Real Girl", when they visit a mall to look for a date for Soos, you can see Melody (the girl Soos later dates) working at a meat stand.
  • Chekhov's Skill: Dipper saves the day by leaping a good distance off a cliff's ledge in Gideon Rises. Pretty cool, but it's especially satisfying to rewatch Dipper vs Manliness and see him practicing and progressing his leaping across cliffs skill during the training montage.
  • Chekhov's Hobby: Dipper's "Lamby Dance" skill.
    • Mabel's mini-golf skills are introduced in the Season 1 episode "Carpet Diem" and then come back as a plot point in the Season 2 episode "Golf War".
  • Cheshire Cat Grin: When Dipper is possessed by Bill, he almost never stops pulling one of these. Behold.
  • Chest Burster: Stan has Waddles perform one in an attempt to scare two kids in "Summerween." Later, Soos also does one, out of the Summerween Trickster.
  • Child Eater: The Summerween Trickster.
  • Christmas In July: Halloween in June
  • City of Adventure
  • City of Weirdos: Deconstructed, as it's revealed in "Society of the Blind Eye" that everybody is being given systematic Laser-Guided Amnesia.
  • Classical Anti-Hero: Most of the main characters are awkward in some way or form, but Dipper in particular really fits the bill.
  • Classic Cheat Code: Ultimate Power! in "Fight Fighters".
  • Cliffhanger: The "Dreamscaperers", "Gideon Rises", and "Not What He Seems".
  • Cloning Blues: The concept and many of its subtropes are largely averted, lampshaded, invoked and subverted during "Double Dipper".
    • Rather than feeling resentful to the original for putting himself above them or trying to take over, the army of Dipper clones are in sync with the original - to the point where they have the same ideas and thoughts at the same time and tend to get along. They have no problem with helping Dipper fulfill his plan even though they won't be benefiting from it, since they're also Dipper and thus agree with the plan in the way he thought of it. It works out fine until Dipper has an epiphany they didn't and decides he doesn't want to follow the plan any more.
    • They are aware that they are expendable and don't seem to mind - #2 is even reassuringly points out before the plot happens that if they do go nuts Dipper can just get rid of them easy using water - and they treat being disintegrated as more of an inconvenience than anything.
    • They avert Kill and Replace, even when they briefly revolt against Dipper. At no point do they even think of replacing the original Dipper for more than a few minutes, and make sure he's comfortable while they do so.
    • In "Boyz Crazy", it turns out all the singers in Sev'Ral Timez are clone lab rats.
  • Cloudcuckoolander: Quentin Trembley. Full stop. Mabel, Old Man McGucket, Soos and possibly Stan count as well.
    • Actually, most people from Gravity Falls count as cloudcuckoolanders.
  • Cloud Cuckoolanders Minder: Dipper to Mabel, most of the time.
  • Clueless Deputy: Deputy Durland.
  • Collector of the Strange: Grunkle Stan sure heaped together a whole hodgepodge of oddities when he created the Mystery Shack.
  • Comical Overreacting: A somewhat common joke on the show. For example, when Mabel and her friends find out a concert they want to go to is sold out:
    Grenda: This night is ruined!
    (Candy falls flat on her face)
    Candy: I welcome you, death.
  • Coming-of-Age Story: Several of Dipper's experiences in Gravity Falls include learning about himself, defending a first crush, and boldly standing up for what is right; all elements of this trope.
  • Con Artist: Grunkle Stan.
  • Confusing Multiple Negatives: The song "Don't Start Un-Believing" the lyrics of which include "don't start un-believing / never don't not feel your feelings."
  • Conspicuous CG: All the vehicles are rendered in CG, and so is the water in certain shots from the second episode.
    • The giant Gideon robot is rendered in CGI in some shots, though with shading touches that don't really make it a problem. Otherwise, he's drawn traditionally.
  • Conspicuously Light Patch: The bowling shoes in this shot.
  • Conspiracy Theorist: Dipper. Considering where he lives, it's quite understandable.
  • Continuity Cavalcade:
    • "Scaryoke", since it's the Season 2 premier, has a noticeably high number of references to previous episodes.
    • In "Into The Bunker", The Shapeshifter takes forms of previous antagonists of Season 1.
    • In "Sock Opera", Bill Cipher tries to persuade Dipper into making a deal with him that will effect Mabel's efforts, stating "What has she ever done to return the favor?" whilst showing flashbacks of his sacrifices in Season 1.
    • Both of the Time Travel Episodes, "The Time Traveler's Pig" and "Blendin's Game".
    • In "The Love God", the titular character entices Mabel with a love illusion potion, which shows all of Mabel's ex-crushes from previous episodes, like Mermando ("The Deep End") and Gabe ("Sock Opera").
  • Continuity Nod: Besides the Myth Arc hints, there's the time when Dipper asks Mabel if they've got any pictures of the gnomes they saw the first episode and Dipper apologizing to Toby Determined for accusing him of murder in "Headhunters".
    • The "S" on the Mystery Shack sign was knocked off in "Headhunters". It has since yet to be fixed and appears broken in every following episode.
    • Mabel shows her scrapbook in "Dipper vs Manliness". You can see that it has a picture of the beheaded wax Stan from "Headhunters".
    • In the episode "The Time Traveler's Pig", the pilot of the wagon on the Oregon Trail exclaims "By Trembley!"
      • In "The Time Traveler's Pig", the show has a moment for all the previous episodes.
    • In "Carpet Diem", Waddles can be seen wearing the top hat Quentin Trembly gave to Mabel.
    • In "Boyz Crazy", Dipper sees Mabel dancing happily and comments about if she ate Smile-Dip again.
    • In "Irrational Treasure", Mabel comments that she doubts Deputy Durland can read. In "Bottomless Pit" Durland asks Stan to teach him to read.
    • In the online game "Mystery Shack Mystery", one of the codes is EVER SEEN STAN'S TATTOO? Indeed, he has one, but only a small portion of it is ever seen. In "Dreamscaperers", when Bill remembers Stan Pines, a full picture of his tattoo is shown.
      • One of the Dipper's Guide to the Unexplained shorts focuses on the kids trying to see his tattoo, and we even get another continuity nod in the short when we see Dipper's forehead and birthmark again for the first time since Double Dipper.
    • The "Fixin' It with Soos" shorts show that Soos is still living in the now cleaned-up extra room that Dipper and Mabel found in "Carpet Diem".
    • In "Sock Opera", upon seeing Gabe, Mabel comments that she was just getting over Mermando, her previous crush and the one she shared her First Kiss with in "The Deep End". Dipper, unimpressed, responds with saying that he didn't care for him (obviously still embarrassed over the Reverse CPR incident).
      • Also in that episode, Bill Cipher appears and they have a tense (on Dipper's part) conversation about the last time they met, with Dipper referring to Bill trying "to destroy his uncle's mind" in "Dreamscaperers". Bill also comments "You missed me. Admit it, you missed me!"
      • Later on, Bill shows flashbacks of previous episodes in season 1 when he tries to persuade Dipper into making a deal with him. Doubles as a Continuity Cavalcade.
      • Also, the laptop that Soos found at the end of "Into the Bunker" has a major plot point in this episode.
    • In "Into The Bunker", Dipper remarks that zombie movies are a lot less scary when you've fought actual zombies, a reference to the previous episode.
      • Wendy says towards the end that if Dipper ever stopped being her friend, she would "throw herself into the Bottomless Pit", referring to the Season 1 episode "Bottomless Pit".
    • In "Soos and the Real Girl" Dipper says that bringing a videogame character to life can bring nothing but trouble, citing his own experience with Rumble McSkirmish. Rumble himself has a cameo in the same episode.
      • In the same episode, when Soos is flirting with a girl who's eating meat, he mentions to her that he was "once a pig".
    • In "Society of The Blind Eye", Mabel's previous crushes are mentioned several times (like Mermando from "The Deep End" and Gabe from "Sock Opera"), as she wants to erase the memories of all her romantic failures during the course of the summer.
      • Also, since they took down the titular society, whose purpose was to erase the memories of the normal residents to make them unaware of the town's paranormal phenomenon, the people have been prone to notice the supernatural more often, like Dipper fending off a vampire bat being the headline in "Northwest Mansion Noir".]]
    • In "Blendin's Game", Blendin Blandin returns to have revenge on Dipper and Mabel for what they did to him in "Time Traveler's Pig".
    • Look closely at Grunkle Stan's hand in "Blendin's Game" and "The Love God". He's still wearing the bandage seen in the credits from "Society of the Blind Eye".
    • At the end of "Northwest Mansion Noir", McGucket is shown to have become a bit more down to Earth since having his memories back in "Society of the Blind Eye". He also mentions "having fixed the laptop", which was found in "Into the Bunker" and destroyed by Bill (in Dipper's body) in "Sock Opera".
      • Pacifica feels bad for her ancestors' crimes, and that includes the Gravity Falls "founder" (discovered by Dipper and Mabel to be a fraud in "Irrational Treasure") who is frequently shown through paintings in this episode.
      • When Pacifica asks Dipper for help, he is sceptical at first because she has been "trying to humiliate him and Mabel before", ("Double Dipper", "Irrational Treasure" and "The Golf War")
  • Continuity Porn: The show is known for having extremely strong continuity. Almost every plot thread that's thrown into the air has to come down eventually.
    • "The Time Traveler's Pig" anybody?
    • And then in "Dreamscaperers", when clips of Stan from various episodes are all on display in his mind.
  • Conveniently Timed Distraction: In "Not What He Seems", when Stan needs to escape from the agents in the police station, a gravity anomaly occurs which Stan takes advantage of to help him escape.
  • Cool Boat: Soos' "S.S. Cool Dude." Averted with the Stan-O-War.
    Soos: Dude, you could totally use my boat for your hunt! It's got a steering wheel, chairs; normal boat stuff.
  • Cool Old Guy: Grunkle Stan.
  • Cosmic Horror Story: Things seem to be leaning in this direction, what with Bill Cipher finally on the scene. His motivations, plans, and the true extent of his powers are still vague or entirely left unsaid, but there's no doubt at all that he's by far the most powerful being in Gravity Falls, if not the entire world or universe.
  • Crappy Carnival: In "The Time Traveler's Pig." Stan spared every expense.
  • Crazy Cat Lady: Lazy Susan.
  • Crazy Jealous Guy: Lil' Gideon to Mabel
  • Crazy-Prepared: Dipper brings 17 disposable cameras for a monster hunt in episode 2. This is because he's Genre Savvy enough to realize that cameras keep getting destroyed or lost during monster hunts.
  • Creator Cameo: Alex Hirsch provides the voice for Grunkle Stan, Soos, Old Man McGucket, Bill Cipher, Jeff the Gnome, Quentin Trembley, and Paper Jam Dipper.
    • He also appears briefly on the television in "Bottomless Pit!"
    • Hirsch (or at least the bottom half of his face) appears on one of the photographs during the title sequence.
  • Credits Gag: There's a different cryptogram in the ending credits of each episode. To decode the cryptograms, each letter must be replaced with the letter that comes three spaces before it. The first episode's cryptogram reads "ZHOFRPH WR JUDYLWB IDOOV." Once decoded, it reads "WELCOME TO GRAVITY FALLS."
    • Once decoded, Episode 2's cryptogram reads "NEXT WEEK: RETURN TO BUTT ISLAND".
    • Episode 3: "HE'S STILL IN THE VENTS".
    • Episode 4: "CARLA, WHY WONT YOU CALL ME?".
    • Episode 5: "ONWARDS AOSHIMA!"
    • Episode 6: "MR. CAESARIAN WILL BE OUT NEXT WEEK. MR. ATBASH WILL SUBSTITUTE."
      • Caesarian and Atbash are both ciphers, Caesarian being the three-letters-back code, while Atbash is the Z=A-Y=B-etc. code. So, there's a technical break in the mix.
    • Once decoded using the Atbash code, Episode 7's crytopgram reads PAPER JAM DIPPER SAYS: 'AUUGHWXQHGADSADUH'". The cryptograms in later episodes are also solved using Atbash.
    • Episode 8: "E. PLURIBUS TREMBLEY".
    • Episode 9: NOT H.G. WELLS APPROVED!
    • Episode 10: SORRY, DIPPER, BUT YOUR WENDY IS IN ANOTHER CASTLE.
    • Episode 11: THE INVISIBLE WIZARD IS WATCHING.
    • Episode 12: BROUGHT TO YOU BY HOMEWORK: THE CANDY.
    • Episode 13: HEAVY IS THE HEAD THAT WEARS THE FEZ.
    • Episode 14 supplied a number substitution coded message (gematria), with dashes between letters and regular punctuation left as usual. The translated message reads: NEXT UP: "FOOTBOT TWO: GRUNKLE'S GREVENGE"
    • Episode 15: VIVAN LOS PATOS DE LA PISCINA note 
    • Episode 16: BUT WHO STOLE THE CAPERS?
    • Episode 17: HAPPY NOW, ARIEL? note 
    • Episode 18: IT WORKS FOR PIIIIIIIIIIIIIIIIIGS!
    • Episode 19: TO BE CONTINUED...
    • Episode 20: Episode 20 actually has two of these, one of which is in the footage above the credits and is needed to decode the normal one. first is an A1Z26 cipher that translates REVERSE THE CIPHERS, which is a hint for when we see the second, which is another A1Z26 cipher, but it's reversed like an Atbash. as in Z=1, A=26. so, once you translate it knowing this, you get a Caesarian cIpher that can be translated with the usual 3 letters back to spell out SEARCH FOR THE BLINDEYE
    • Season 2 appears to have the standard credit ciphers (this time Vigenere cipher with the key hidden in each episode) as well as additional ciphers in Freeze-Frame Bonuses AFTER the credits.
    • Episode 1: In credits: WELCOME BACK (the key is "Widdle" in Gideon's Cell). After credits: THE MAN DOWNSTAIRS IS VERY CLEVER, CAN HE HIDE HIS PLANS FOREVER?

    • Episode 4: In credits: WE'VE ALL HAD SOME FUN TONIGHT, BUT LET'S NOT FORGET WHO THE REAL 'PUPPET MASTERS' ARE: REPTOIDS WHO HAVE INFILTRATED OUR GOVERNMENT (the key is "Cipher" on the attic's ceiling, seen after Bill hijacks Dipper's body). After credits: NO PUPPET STRINGS CAN HOLD ME DOWN / PATIENTLY I WATCH THIS TOWN / ABNORMAL SOON WILL BE THE NORM / ENJOY THE CALM BEFORE THE STORM
    • Episode 5: In credits: ANTHYDING CAN HADPLEN (the key is "Bearo"). After credits: WINNING HEARTS BY DAYLIGHT! / POSSESSING ROBOTS BY MOONLIGHT! / HER EMOTIONAL BAGGAGE IS A REAL FRIGHT! / SHE HAS THE ONE NAME GIFFANY!
    • Episode 6: In credits: CHECK OUT DR. WADDLES’ LATEST BOOK: "A BRIEF HISTORY OF OINK OINK OINK OINK OINK" (the key is "Noncanon", as seen on the side of the top railing in Harry Claymore's house. After credits: ALL ANIMATION IS BLACK MAGIC

    • Episode 11: In credits THE ORIGINAL MYSTERY TWINS and after the credits: THIRTY YEARS AND NOW HE'S BACK. THE MYSTERY IN THE MYSTERY SHACK. Talk about Wham Line.
  • Creepy Child: Li'l Gideon, definitely.
  • Crossover Punchline: This video [1] teases a minor crossover with Rick and Morty.
  • Curb-Stomp Battle: Between Dipper and Rumble McSkirmish.
  • Cursed with Awesome: The fact that a dating simulation is alive in "Soos and The Real Girl", aside the fact that she's a crazy Yandere of course, could sound quite interesting and exciting for players who are lonely. Not only would she be a cute anime girl you would be able to talk to like a normal person, but there would be possible Video Game Perversity Potential as well...
  • Cut a Slice, Take the Rest: How Mabel eats Smile Dip.
  • Cutaway Gag: Occasionally appears in some episodes. Some usually foreshadow the events of the episode.
  • Cute and Psycho: Li'l Gideon.
  • Cute Bruiser: Mabel.
  • Dangerously Genre Savvy: Bill Cipher. Not only was this guy able to trick Dipper, the smartest, most Genre Savvy character on the show, into making a Deal with the Devil, but he was able to do it without even trying that hard. No force or bold-faced lies were required, all he did was use his words.
  • Darker and Edgier: Than pretty much every other current Disney Channel show, frequently using the terms "killed" and "died", and Gideon trying to cut out Dipper's tongue in Episode 4 is likely something you won't be seeing on most of them anytime soon.
    • One episode even had live wax statues trying to chop off Grunkle Stan's head (not to worry, though: they only succeeded in decapitating his wax figure instead).
    • In "Fight Fighters" Grunkle Stan reveals that he owns ten guns, specifically to shoot anyone who tried to sneak a ladder into his house.
    • Not to mention that in the episode "Gideon Rises", Dipper is shown with a nose bleed from the giant Gideon-Bot chase scene. This is the first occurance of seeing someone visibly bleed in the show, and blood itself is pretty rare for a Disney show.
    • In "Dreamscaperers", it's shown that Book 3's entry on Bill Cipher is covered in blood. How did this show make it onto Disney, anyway?
    • Season 2 appears to be shaping up as this. The first episode centers around what Dipper believes is a zombie that was eventually revealed as a clan of gnomes on top of each other. "Scary-oke" features Dipper summoning REAL zombies.
    • Into the Bunker. Experiment 210 shapeshifts into various Eldritch Abominations; in one particular instance it taunts the twins by shifting into Mabel, then Dipper, then shapeshifts into them both as a nightmareish monstrosity.
      • Later, the Experiment disguises itself as Wendy, and Dipper buries an axe into 210!Wendy's abdomen, with no Gory Discretion Shot.
    • In Sock Opera, when Bill possesses Dipper's body, he finds causing himself pain hilarious. It's mostly Played for Laughs, but the sight of Bipper repeatedly slamming a drawer on his own hand and impaling it with two forks in the process all while wearing a manic grin is...disturbing.
    • Not What He Seems features a more mundane threat than most earlier episodes, but one that is arguably more horrifying for that reason. When Dipper and Mabel first discover that the man they've been living with throughout the summer has been lying about his identity, coupled with not too subtle hints that he killed the real Stan, their horror and that of the audience is dramatically greater than when they face any of the supernatural threats that they regularly have to deal with. The anger, sadness, and betrayal that the main characters feel is palpable throughout the rest of the episode, and even though it's ultimately revealed that Stan really is their great uncle (just not the one that they thought) and that he loves both them and his brother (the other Stan) greatly, the premise alone is enough to make this episode the darkest in the series.
  • Dartboard of Hate: The Gleeful house contains one with a picture of Stan.
    • In "Gideon Rises", after Stan reveals that Gideon has been monotoring everyone via camera, there's a blink-and-you'll-miss-it moment in which one of the screens shows Pacifica shooting darts onto a picture of Mabel.
    • Robbie has one of Dipper.
  • Deadpan Snarker: Grunkle Stan. Dipper has his moments as well.
  • Dead Person Impersonation: The real Stan Pines has been dead for thirty years. We know little else besides this, however, due to the episode ending on a Cliff Hanger.
  • Deal with the Devil: In "Sock Opera", Dipper begrudgingly makes a deal with Bill Cipher since he knows the password to the laptop (which is about to erase data in a short amount of time because of many failed password entries), in exchange that Bill will have a puppet. The thing is, he wanted Dipper as his puppet.
  • Deliberately Monochrome: Played with in Episode 8. Dipper holds up a postcard of the town square, then lowers it to a sepia-toned town square. He was really just looking through some very dirty glass that was being carried across the street.
  • Demonic Possession: So far, this has happened twice. First with Mabel, who gets possessed by a pair of ghosts in "The Inconveniencing". Then taken more literally in "Sock Opera", where Dipper is tricked into allowing Bill Cipher to possess him. The second example also crosses over with Grand Theft Me, as Dipper's soul is forcibly ripped out of his body in the process.
  • Department of Redundancy Department: The "Rock That Looks Like a Face" Rock: The Rock That Looks Like A Face.
    • Also, "Fight Fighters".
  • Depending on the Writer: There seems to be come disagreement among the writers on Soos's relationship with Stan: he either looks up to him as a father figure, or he has some kind of awkward, half-formed crush on him.
  • Detectives Follow Footprints: How Dipper and Mabel found the axe in "Headhunters."
  • Disappeared Dad: Soos's father walked out on him when he was a kid.
  • Disproportionate Retribution: Played for Laughs with Old Man McGucket's giant robots, but a much darker example occurs when Gideon's response to Dipper breaking up with him in Mabel's stead is to use his telekinetic powers to try to cut out his tongue.
  • Distinguishing Mark: The Big Dipper-shaped birthmark on Dipper's forehead.
  • Ditzy Genius: Soos is actually quite smart, with competent knowledge of machinery and construction, and many nuggets of wisdom to give to the other characters. You would never guess this based on how he acts.
  • Does This Remind You of Anything?: In a way that is darker than usual for this trope. "Society of the Blind Eye" features a society that protects people from the supernatural phenomena of Gravity Falls or other horrible experiences by erasing their memories, which could be easily interpreted as an analogy on how people use drugs like ecstasy to make them "feel better". Not to mention that the memory wipes are heavily implied to cause brain damage.
  • Dogged Nice Guy: Gideon is a deconstruction of this trope. He is devoted to Mabel but she just wants to be friends, and in-universe everyone seems to think that his attempts to win her over are charming...but the truth is, Gideon is an Ax-Crazy, Entitled Bastard who uses emotional manipulation to trap Mabel into a relationship. He performs over-the-top acts of kindness, manipulates her into going into more dates with him by asking her very publicly in front of large crowds of Gravity Falls citizens who think it's just so adorable that Gideon might finally get a girlfriend, and completely ignores her wish to not be in a relationship with him. Eventually, Dipper tries to break the news that Mabel is not interested in Gideon to him, and Gideon responds to this by attempting to murder Dipper because he believes that Dipper got in between him and Mabel. Thankfully, Mabel sees this and intervenes, and she rejects him, not only romantically, but as a friend now, too.
    Mabel: (after rejecting Gideon again) But we can still be makeover buddies, right? Wouldn't you like that?
    Gideon: Really?
    Mabel: (rips amulet away from Gideon) No, not really! You are like attacking my brother, what the heck!
  • The Dog Was the Mastermind: "Society of the Blind Eye" reveals that background characters Toby Determined, Bud Gleeful, farmer Sprott, the burly man who guards the Skull Fracture, the man married to a woodpecker and a random woman are members of a secret society that make the inhabitants forget of the paranormal activities they encountered. Subverted with the leader who has never been seen before.
  • Don't Explain the Joke: In "The Legend of the Gobblewonker," when trying to recruit fishing buddies, Stan interrupts a man about to propose to his girlfriend with this joke: "My ex-wife still misses me, but her aim is getting better!" After repeating the punchline, he explains, "It's funny because marriage is terrible."
  • Doting Parent: Bud Gleeful.
  • Double Standard: Abuse, Female on Male: Averted in "Soos and the Real Girl", where Giffany's attempts to control, manipulate, and eventually abduct Soos are depicted as horrible and disturbing.
  • Double Take: The phrase "Wait, what?" shows up quite often on the show.
  • Downer Ending: "Dreamscaperers"
  • Dream Walker: Bill Cipher
  • Drunk on Milk: Subverted in "Gideon Rises", where Stan briefly tries to get drunk on very expired apple cider. Apple cider ferments with age, the audience just isn't directly told this.
    • Played straight when Grenda drinks expired milk, saying that "I can see rainbows!" Then she passes out.
  • Drives Like Crazy: Grunkle Stan
    Stan: "Road safety laws, prepare to be ignored!"
  • Dysfunction Junction: As of Season 2, the whole cast is starting to become this. And in a Disney show of all places!
    • Dipper is a shy, insecure, pre-pubescent kid who's nervous about his body and attempts to mask it by being The Smart Guy in the group. May also be a borderline Nightmare Fetishist with his fascination with the paranormal.
    • Mabel is, well, Mabel, and she most likely has a form of ADHD. Also, in one episode, when she lost Waddles, she became incredibly and agonizingly depressed to the point she seemed to have lost the will to live!
    • Stan is practically a kleptomaniac who enjoys being hated, not to mention his cloudy past and his murky history with the weird in Gravity Falls.
    • Wendy acts cool, but in "Society of the Blind Eye" she stated that she is always really anxious and nervous all the time.
    • Soos had never even met his father, and after several years of having his father-come-home-birthday-present not happen, he grew to dislike celebrating his birthday.
    • Even Pacifica falls under this this, having grown up and being conditioned like a dog to always obey her parents at the sound of a bell, and she is terrified of ever disobeying them. And these are just the main characters..
  • Dude, Not Funny!: In an In-Universe example from "Society of the Blind Eye", Soos enrages Mabel and Wendy when he makes a joke about Lazy Susan's mascara.
  • Early-Bird Cameo: Lazy Susan appears in the diner for a moment in the pilot, and isn't formally introduced until five episodes later.
    • A picture of Robbie can be seen posted on the bulletin board among the other suspects in "Headhunters".
    • Li'l Gideon is featured in a magazine advertisement two episodes before Dipper and Mabel actually meet him.
    • Mr. Poolcheck appears in the Skull Fracture bar an episode before he is introduced in "The Deep End".
    • The band Sev'ral Timez' movie appears in "Carpet Diem".
    • Bill Cipher appears on an arcade game's screen in the cold open of "Fight Fighters." His body is colored green rather than its normal yellow, but image is clearly Bill.
  • Early Installment Weirdness: The first episode was narrated by Dipper and ended with him writing in the journal, kind of like an episode of Doug. After that, the narrations seem to have been dropped.
  • Earth-Shattering Kaboom: Stan's portal device is revealed to have the capacity to do this in "Not What He Seems". It doesn't, but it comes awfully close.
  • Earworm: It's mentioned in-universe that the songs of Sev'ral Timez are quite catchy. A rap song that Soos enjoys is also stated to be a serious earworm, and Wendy comes close to using a memory-erasing device to get rid of it.
  • Easter Egg: The messages in the credits at the end of every episode. To decode them, you have to send each letter "three letters back", as explained when the intro is played backwards. JHW WKH SLFWXUH?
    • Episode 7 onwards uses the Atbash cipher. YV HFIV GL PVVK FKWZGVW.
    • Speaking of backwards messages, in "Dreamscaperers", Gideon's chant to summon Bill Cipher might sound like gibberish, but when played backwards, it reveals a secret: Gideon is saying "Backwards Message" backwards.
    • Smaller secret messages appear during the show. For example: the binary code that appears diring Giffany's flashback in "Soos and the Real Girl" translates to "SPACEJAMTWO".
  • Eaten Alive: In "The Land Before Swine", Old Man McGucket is eaten by a pterodactyl.
    • Both Soos and Gorney are eaten alive in "Summerween".
    Gorney: I've been twaumatized!
  • Elaborate Underground Base: Stan has one under the Shack.
    • The Author of the Journals has what looks to be an even bigger one under the tree where Dipper first found 3.
  • Eldritch Abomination: The Time Baby, especially if you've read the document explaining what it is.
    • Bill Cipher.
    • Experiment 210
  • Eleventy Zillion: Mabel, while high on Smile Dip, responds to Dipper's question of how many packs she's had with "Bleventeen".
  • Embarrassing Middle Name: Robbie's middle name is revealed in "The Love God".
    Mrs. Valentino: Robbie Stacey Valentino! There's a little girl here to see you!
  • Emo Teen: Robbie.
  • End of the World as We Know It: Very narrowly averted in "Not What He Seems". And we don't yet know if we've seen end of it either.
  • Enemy Mine: In "Northwest Mansion Mystery" Pacifica asks Dipper for help when a Lumberjack Ghost wants her and her family dead. Dipper of course, is suspicious, because he knows how terrible Pacifica has been towards him and Mabel. Despite his protests, and with Mabel's urging, Dipper agreed and decided to see the job through, hoping to get Pacifica off his back. Dipper's suspicion was eventually vindicated, since the entire plot was a ploy by the Northwests to cover up their own treachery, just so they can continue to deny commonfolk access to their annual party. Disgusted by this revelation, it end his truce with Pacifica. However, Dipper later finds out that it wasn't Pacifica, but rather, her father who used and tricked him. Upon seeing how regretful and horrified Pacifica is at her family's lying, backstabbing ways, he decides to give her a second chance.
  • Enfant Terrible: Lil' Gideon
    • The Time Baby, probably.
  • Even Evil Has Standards: Gideon Gleeful, the nine-year-old whose hobbies include abusing his parents, summoning demons, and murder via oral mutilation, was legitimately disturbed by the actions of Bill Cipher. Not because he was morally opposed to them, but because he just found them that sporadic and outlandish.
  • Everybody Laughs Ending: In "Summerween." See Evil Laugh below.
  • Everyone Calls Him Barkeep: The credits only refer to Tyler as "Cute Biker".
  • Everyone Has Standards: Several characters on the show have had moments of this.
    • Mabel is a hyperactive goofball who seems to takes every opportunity to do whatever strange thing comes into her head. But in "Sock Opera", when she found out her crush of the week was so obsessed with puppets he sometimes makes out with them, even she considers it just a step too weird.
    • Robbie is a complete Jerk Ass who houses a serious dislike for Dipper for having a crush on Wendy, his at the time girlfriend. But, when presented with an unresistant opportunity to give Dipper a beating, he can't bring himself to go through with it.
    • This exchange in "Soos and the Real Girl":
    Stan (Referring to dating): Soos, a little advice. You need to get rich. Or lie about being rich. Outside of that, I don't like your chances.
    Wendy: Pssh, don't listen to Stan, dude. You're a sweet guy with a steady job and a pickup truck.
    Stan: Would you date him?
    Wendy: Oh, would I, uh... heh, look at that.
    (She hides her face in a magazine called "Avoid Eye Contact Monthly").
  • Everything's Better with Dinosaurs: In "The Land Before Swine"
  • Everything's Better with Llamas: Mabel's llama-hair sweater.
  • Evil Is Hammy: Bill Cipher, so, so much. His voice is loud and unnatural, his lines are strange and sporadic, and his voice pattern is just as unpredictable as he is. One minute he could be talking to you normally, the next he's Suddenly Shouting in a demonically deep tone.
    • Gideon isn't exactly a subtle fellow either.
  • Evil Is Petty/Poke the Poodle: Gideon returns in "Irrational Treasure". Not to carry out an evil revenge scheme on the Pines, but to taunt Stan while the latter was in stocks.
    • Gideon fights with Stan over a pool chair in "The Deep End".
  • Evil Laugh: Stan, Dipper, Mabel, Wendy, Soos, Grenda and Candy indulge in one in Episode 12 after Stan's Warped Aesop.
    • Bill Cipher is very prone to this.
  • Evil Old Folks: Ma and Pa, the ghost owners of the Dusk-2-Dawn convenience store.
  • Expy: The Summerween Trickster closely resembles Noh-Face from Spirited Away.
    • The Shapeshifter in "Into the Bunker" directly resembles the monster from The Thing (1982).
    • The character of Bud Gleeful (a relentlessly cheerful, portly car dealership owner in a T-shirt and shorts) was directly inspired by "The Family Man", the star of a bizarre series of local Florida commercials Hirsch once saw while on vacation.
    • Gideon Gleeful's appearance is almost a dead ringer for 1950s child preacher Larry Larimore.
  • The Exit Is That Way: Simultaneously lampshaded and Averted in "The Hand That Rocks The Mabel":
    (Grunkle Stan exits, slamming door behind him)
    Soos: Dude, wouldn't it be funny if that was a closet, and he had to come back out again and walk out the real door? (opens door and looks out) Nope, real door.
  • Exactly What It Says on the Tin and Bribing Your Way to Victory: the "Insert Token!" machine at the arcade.
  • Extreme Omnivore: Implied when we see one of Mabel's drinks contain a strange cyclops Troll Doll and several dice, all in a green fluid.
    • She also once ate a whole tube of toothpaste because "it was so sparkly".
    • Old Man McGucket is even more so, having eaten such things as books and a live pterodactyl.
  • Eye Colour Change: Mabel's eyes turn green when she's had too much Smile Dip. Additionally, looking into the Gremloblin's eyes causes the eyes of two tourists to match the creature's bright yellow ones.

    F - O 
  • Face Doodling: Stan writing the word "goober" on Dipper's forehead in "Stan's Tattoo".
    • Mabel scribbles "BUTTS" on Blind Ivan's phrenology-map skull tattoo with a permanent marker, much to his consternation.
      Blind Ivan: That's not funny!
      Dipper: (Laughing) It's pretty funny.
      Soos: It's, like, objectively funny.
    • Also used to humorous effect in the episode "Carpet Diem", when Mabel wakes up after her sleepover with "Party Gurl" written on her face in red marker.
  • Face of an Angel, Mind of a Demon: Lil' Gideon.
  • Family-Unfriendly Violence: Oh, Lord have mercy...
    • "The Hand that Rocks The Mabel": Gideon comes very close to cutting Dipper's tongue out with shears.
    • "Summerween": We see a kid get eaten alive, just as a way to show that the villain means business. He lives, and its eventually written off as a joke, but still.
    • "Gideon Rises": Dipper and Gideon get into a fistfight, with several blows shown in full, painful detail. It's not the worst, but physical violence is pretty rare on TV Y7 shows, especially between children.
    • "Scaryoke": The zombies that are accidentally summoned are pretty nasty, and they're shown being mutilated with no holds barred. Probably the only reason it got through was because they don't bleed very much.
    • "Into the Bunker": We see Wendy being axed through the stomach. Sure, it turns out to be a shapeshifting impostor that bleeds green, but it's still an apparently-human character being gored by another human character with no Gory Discretion Shot.
  • Fan Disservice: Old Man McGucket lotioning himself.
    • Every single time Stan takes off his clothes. Which is often.
    • Soos has taken off his shirt on multiple occasions. It's about as unappealing as you think.
    • Sherrif Blubs and Deputy Durland taking off their uniforms to play in a broken fire hydrant in "Dipper vs. Manliness"
    • The gnome that Mabel and Dipper stumble upon bathing himself in squirrels in "Gideon Rising" is pretty disturbing to the main characters.
  • Fantasy Americana
  • Fat and Skinny: Sheriff Blubs and Deputy Durland.
    • As well as Grenda and Candy.
  • Faux Affably Evil: It's hard to deny Bill Cipher's charm, and that's exactly how he wants you to feel.
  • Ferris Wheel Date Moment: Wendy and Robbie have a brief one in "The Time Traveler's Pig."
  • Feuding Families: The Lilliputtians, with a different clan themed for each hole at the mini-golf course.
  • Fiery Redhead: Manly Dan. Averted with his daughter Wendy.
    • However, by Season 2, this is subverted with Wendy once her Character Development kicks in (as exemplified in episodes "Society of the Blind Eye" and "The Love God").
  • Filk Song: Many. Wendy x Dipper isn't a bad place to start.
  • First Kiss: Mabel badly wanted one, and was thrilled when she finally received her first kiss from Mermando.
  • Fluffy the Terrible: Dipper's body is possessed by the completely evil and sociopathic demon Bill Cipher. Of course, Mabel calls him "Bipper".
  • Foil: The twins counter one another's personalities perfectly.
  • Foolish Sibling, Responsible Sibling: Take a wild guess.
  • Foot Popping: Mabel does it when she kisses Mermando.
  • The Foreign Subtitle: Along with the Japanese name seen above, this show has also been given the subtitle Un Verano de Misterios note  in most Spanish-speaking countries. Brazil used a Portuguese-translated version of the title.
  • Foreshadowing:
    • Bill has been in every opening since the first episode, he's in a blipvert at the end of of the opening.
    • In "Tourist Trapped", when Dipper is trying to warn Mabel about Norman, he accidentally opens up to the gnome page of the journal instead of the intended zombie page. Turns out his first guess was more accurate.
    • At the end of "Tourist Trapped", Stan uses a vending machine to access a secret room. That surely won't come into play later.
      • As of season one's finale, it's revealed that behind that vending machine is a secret passage to a laboratory containing something that could only be activated when all three books were gathered.
    • Robbie got an Early-Bird Cameo in "Headhunters" as one of the murder suspects.
    • During Lil' Gideon's song in "The Hand that Rocks the Mabel", he gets everyone to stand up after holding his amulet. Turns out, his amulet gives him Psychic Powers. Dipper was forced to stand up against his will, making Dipper question what just happened.
      • The Number 2 book.
    • There's also a newspaper in one of the earlier episodes which has an ad for a "child psychic".
    • In Irrational Treasure, the top secret document mentions a giant, evil, time-traveling baby from another dimension being frozen in a glacier in Antarctica. Fast forward to "The Time Traveler's Pig", where we see said giant evil baby apparently ruling over the future.
    • If you watch all the shorts and put the images together, you get this. This hints at the Blind Eye society, who become very important in season 2.
    • The awkward, insecure Robbie's personality was shown in its fullest in "The Love God", but it was subtly hinted at an entire season earlier in "The Time Traveler's Pig" if you pay close attention to his actions.
    • In the the "Voice Over" segment from "Bottomless Pit", when Dipper first reveals his new voice to Mabel, she flips out and thinks he switched bodies with somebody. Guess what happened two episodes later?
    • None of this even comes close to the amount of foreshadowing that went into the Stan Twin Theory. Guess what the big reveal was at the end of Not What He Seems?
      • In "The Inconveniencing" if the backwards-talking dog's speech is played in reverse it sounds like it's saying "Must distrust Grunkle."
    • The top of the Mystery Shack Totem Pole depicts not the Thunderbird, but Kolus, the Thunderbird's similar younger brother. The real Thunderbird is seen in the basement right in the room that Stan's brother returns into.
  • Four-Fingered Hands: Most of the characters in the show have four fingers, but some characters, like Stan and Soos, have five fingers on each hand.
    • Making it even stranger is how the cover of Dipper's book features a six-fingered hand. The Shapeshifter in "Into the Bunker" confirms this is a reflection of the author's polydactyly, as can be seen firsthand (or firsthands when he shows up at the end of "Not What He Seems."
  • Four-Temperament Ensemble: Dipper is melancholic, Mabel is sanguine, Grunkle Stan is choleric, and Soos and Wendy are both phlegmatic.
  • "Freaky Friday" Flip: In "Carpet Diem", this happens between Dipper and Mabel, and then later between Soos and Waddles. Hilarity Ensues.
  • Freeze-Frame Bonus:
    • You get a shot of Bigfoot in the opening credits. Blink and you'll miss it.
    • Dipper's book has a lot of these, in the forms of foreshadowing, creepy info about the local monsters, and the occasional joke.
      "Knock! Knock! Who's there? THE FORCES OF EVIL!"

    • Blendin Blandin, the time traveler from Episode 9, can briefly be seen in the first three episodes, fixing the paradoxes the twins caused.

DOVR: JR RXWVLGH DQG PDNH IULHQGV" (PUBERTY IS THE GREATEST MYSTERY OF ALL. ALSO: GO OUTSIDE AND MAKE FRIENDS).
    • When Bill Cipher says "I know lots of things. Loooots of thiiiings." his triangle flashes countless images, and if you pause them you can see, in that order: John F. Kennedy (Implying something), Blurry UFOs, Mayan scriptures, one of the Mysterious 3 book that Dipper owns, the moon landing, one of the pages of the 3 book, a skull with a cigarette, Stonehenge, The Pyramids, Stan going for his secret vending machine door, The Sasquatch seen in the opening, another page of the book, Crop Circles, the secret room where the twins found Quentin Trembley, a statue of Nathaniel Northwest, part of the stamp on the postcard from the intro, various clocks, what seems to be a abandoned warehouse, a maximum security prison, then it repeats the blurry UFOs and the blank scriptures.
      • From the same episode, pay very close attention to the picture on Bill's face when Gideon mentions Stan.
    • When Dipper phases through the floor in Sock Opera you can see a box with an antenna and the government agency's symbol on it. Later agents Powers and Trigger can be seen in seated in the audience at Mabel's show hiding behind newspapers.
    • During the second "Mabel's Guide to Life" short "Mabel's Guide to Stickers," Mabel holds up a book of myths. In the Aztec portion of the book there is an Aztec retelling of the Air Bud franchise.
  • Fresh Clue: In "Into the Bunker", Dipper, Soos, Mabel, and Wendy go into the bunker of the author of the journal owned by Dipper. Soos notes that a can of beans in there was recently opened, so the author might still be alive in there.
  • Freudian Excuse: Pacifica's parents have been literally treating her like a dog, resulting in her Jerkass Façade.
  • Fun Bag Air Bag: In the storyboard work of "Into The Bunker" Dipper was originally supposed to fall straight into Wendy's chest when in the closet. It was scrapped for obvious reasons.
    • That said, in the actual episode, Dipper is momentarily slammed face-first into Wendy's chest by decontamination spray.
  • Fun Personified: Mabel. Everything about her just screams fun and games.
  • Funny Foreigner: Candy Chiu, Mabel's Asian and Nerdy friend. She can speak English just fine, but her accent is very thick.

  • Genki Girl: Mabel.
  • Genre Savvy: Once per Episode.
  • Genius Ditz: Mabel isn't exactly a ditz, per say, she's just extremely unfocused and not nearly as rational as her brother. She's got a lot of helpful talents, though, most notably in the realm of arts.
  • Ghostly Goals: Ma and Pa seek revenge on teenagers.
  • Giant Novelty Check: Featured in the cold open of "Little Dipper."
  • Gilligan Cut: "It's not like I lie awake at night thinking about her!" Cut to Dipper lying awake at night, thinking about Wendy.
  • Girly Bruiser: While not afraid to get her hands dirty, Mabel is definitely on the girly side of the spectrum, especially when teamed up with Wendy. However, not only can she fight alongside her brother with a surprising amount of competence for a Cloud Cuckoo Lander, but it's not even that difficult to provoke her into violence.
  • Glass-Shattering Sound: Parodied. In one episode, Pacifica sings so high she shatters a plastic cup.

  • A God Am I: Mabel declares herself to be the god of destruction after finding some illegal fireworks.

  • Gonky Femme: Grenda is fat and very masculine looking compared to her friends, Mabel and Candy, but rarely if ever acts tomboy, and personality-wise, don't differ to the aforementioned girly girls she has a friends.
  • Good Vs Good: In "Not What He Seems", Stan only committed illegal acts to rescue his brother from another dimension. The federal agents, while incorrect about Stan's true intentions, were rightfully chasing a guy who committed serious crimes. Dipper and Mabel nearly ruined Stan's plot to save his brother so that they could stop a machine that could have destroyed the world.
  • Gory Discretion Shot: Averted! In "Into the Bunker," we see Dipper full-on bury the axe in the shapeshifter. In Wendy form.
  • Goshdang It To Heck: Most cussing that appears gets this treatment. Though at least for Mabel, it's arguably in-character.
    Mabel: (After losing a minigolf game): Darn! Poop, heck, darn!
  • Government Conspiracy: In "Irrational Treasure."
  • Grand Theft Me: In "Sock Opera" Bill possesses Dipper's body in order to destroy the laptop and then the journal, the latter plan backfiring.
  • Grappling-Hook Pistol: Mabel has one.
  • G-Rated Drug: Smile Dip, especially after eating "bleven-teen" packages of it in "The Inconveniencing".
  • Great Big Book of Everything: Dipper finds a book in "Tourist Trapped" with a six-fingered hand and a "3" on the cover; it gives clues to all the strange happenings in Gravity Falls. The book ends abruptly in the middle and the author is unknown. Li'l Gideon has a similar book with a "2" on it.
    • And, contrary to the skeptical front he puts on, Stan has secretly had the first in his possession all along, and has been searching for the other two for some time. When combined, the three power a massive portal device of as-yet-unknown function in the Mystery Shack basement.
  • The Great Politics Mess-Up: Considering that Rumble McSkirmish is from an 80's video game, he believes the Soviet Union is still around.
  • Grimmification: Many of the stories are taken from American folklore, tall tales and conspiracy theories, but darkened up.
  • Grotesque Cute: The baby pterodactyl in "The Land before Swine" is adorable. It's also just the right size to swallow people alive.
  • Guilty Pleasures: Dipper enjoys listening to girly pop sensation BABBA.
  • Gulliver Tie Down: Mabel courtesy of the gnomes.
    • Later happens to Pacifica Northwest in "The Golf War," courtesy of the aptly named Lilliputtians.

  • Heel Realization: Minor one for Dipper, when due to Time Travel he meets Wendy at five years old and she thinks he's cute.
    Dipper: Thank you. I mean... you're super young, so this is weird.
    Mabel: Heheh, now you know how she feels, creep.
    Dipper: Heh heh, yeah, I-uh. Huh. Wow. Wooow...
  • Her Code Name Was Mary Sue: Stan, in his story "Grunkle Stan Wins the Football Bowl."
    • Mabel, in her sock puppet play "Glove Story: A Sock Opera".
  • Heroes Want Redheads: Dipper's crush on Wendy. Doubles as a case of Little Boy Seeks Big Girl.
  • Heroic BSOD: Mabel goes into a brief but pretty major one (for her, at least) in "The Hand that Rocks the Mabel" when she finds out she has to marry Gideon, sending her into "Sweater Town".
    • She goes into an even worse one in "The Time Traveler's Pig", where losing Waddles to Pacifica sends her into a BSOD lasting over a month.
    • A more significant BSOD involving Dipper occurs during "Dreamscaperers", where after searching through Stan's memories to discover what Stan really thinks of him, he mishears a conversation that occurs between Stan and Soos and is led to believe that Stan really hates him.
  • Homemade Sweater From Hell: Averted with Mabel's sweaters. She knits them herself and enjoys wearing them regularly.
  • Honest John's Dealership: The Mystery Shack's gift shop.
    • Gleeful Auto Sales.
  • Hope Spot: At the end of "Dreamscaperers." They stopped Bill and protected the combination to Stan's safe, and just when it seems eveything turned out fine, Gideon shows up with a wrecking ball.
  • Horrible Judge of Character: The whole town of Gravity Falls is this, considering they have a habit of looking up to the wrong kind of people:
    • The townspeople fawned over Gideon, an Ax-Crazy little brat who attacked Dipper using lamb shears, summoned a demon so he could steal Stan's deed to the Mystery Shack, and chased after the twins using a giant robot. They finally learn the truth when Stan exposes Gideon's illegal surveillance cameras.
    • They also look up to the Northwest family, the founders of Gravity Falls, in spite of their snobbish, classist attitude. And as it turns out, the Northwests were not the founders and have been cheating and scamming the townsfolk for a century and a half.
  • How We Got Here: How the first episode started.
  • Hypocritical Heartwarming: In "Scary-oke".

    • Mabel is hardly ever seen without one of her homemade turtleneck sweaters.
    • Ditto for Dipper's cap.
    • Grunkle Stan's fez and black tuxedo.
    • Soos's question-mark staff shirt.
    • Wendy's green plaid shirt and lumberjack hat.
  • Idiot Ball: A literal example with the world's most distracting object. Even Stan himself fails to notice the danger outside the shack while looking into it.
  • Idiotic Partner Confession: Happens in the 20th episode, where Dipper begs Wendy not to leave and tells her they need her and Soos almost lets slip that he has a crush on her.
    Soos: Yeah, especially Dipper because of his giant crush on...
    Soos: You...
    Soos: —calyptus trees! Ha! The kid loves eucalyptus trees! *to himself* Saved it!
  • I Don't Want to Ruin Our Friendship: This is the main reason Dipper can't bring himself to confess his feelings for Wendy. When the beans are finally spilled, she doesn't return his feelings, but their friendship isn't in any way changed.
    • Also the reason Mabel didn't want to reject Gideon at first.
  • I Just Want to Be Special: Dipper has expressed this desire on more than one occasion.
  • I Know Mortal Kombat: Averted; although Dipper is skilled at the game Fight Fighters, he's no match in a real brawl against an older, larger opponent like Robbie, and certainly not against Rumble McSkirmish himself.
    • Soos is convinced that years of watching zombie movies have given him the skills necessary to survive in a real-life attack. Seconds after he stops talking, he's bitten by the zombie behind him that he wasn't paying attention to.
  • I'm a Humanitarian: Old Man McGucket was more than okay with eating Soos in his human body.
  • In Love with Love: One of Mabel's main goals while at Gravity Falls is to have an "Epic summer romance". She therefore flirts with every non-relative guy she meets that's even remotely close to her age.
  • Insult Backfire: Happens in "Dreamscaperers":
  • Interspecies Romance: Between Mabel and the gnomes.
    • And between Mabel and Mermando.
    • It's legal to marry woodpeckers in Gravity Falls. Several people have taken advantage of this.
    • In "The Love God", Mabel convinces the titular character to make a snake and a badger stop fighting and fall in love. This is followed by Mabel's declaration that "they're going to make a snadger".
  • In Touch with His Feminine Side: Dipper. The episode "Dipper vs. Manliness" was partially about him learning to accept this about himself.
    Dipper: So maybe I don't have muscles, or hair in certain places, and.. sure, when a girly pop song comes on the radio, sometimes, I leave it on! 'Cause dang it, top 40 hits are in the top 40 for a reason! They're catchy!
  • Intoxication Ensues: An example with a G-Rated Drug occurs in "The Inconveniencing". Mabel discovers a rack of Smile Dip, a candy banned in the U.S., for sale in an abandoned convenience store. After consuming several packets, apparently unaware that it's a mind-altering substance, she slips into a bizarre hallucinatory delirium that ends with her riding some sort of multi-headed hand dolphin and yelling "The future is in the past. Onwards Aoshima!" while the hand dolphin proceeds to sprout more heads out of its hands and fire rainbow lasers out of every mouth while making car alarm noises.
  • I Have Your Wife: Gideon attempts this after kidnapping Mabel and Dipper. It doesn't work.
  • I Want to Be a Real Man: Dipper in "Dipper vs. Manliness."
  • I'll Never Tell You What I'm Telling You: Soos pulls one when Gideon demands to know where Stan is. To his credit, he at least realizes how stupid it was immediately after doing so.
  • Imagine Spot: In "The Legend of the Gobblewonker", when Dipper asks Mabel what she'd do with $500, she imagines blowing it all on a giant human-sized hamster ball.
    • In the same episode, Dipper has one detailing an interview he would have if he caught the Gobblewonker.
      • Which would then be crashed by Mabel in said hamster ball.
    • Two from Dipper in "Double Dipper": the first was of him dancing with Wendy; the second, of Wendy dancing with Robbie and then punching Dipper in the gut.
  • Impossibly Tacky Clothes: Mabel's sweaters are sometimes this.
  • Improbable Weapon User: Mabel, who gets props for using a leaf blower to blow away a thousand gnomes.
  • Improvised Weapon: When they encounter a monster, the twins typically just use whatever they have on hand. Weapons so far include a shovel, living gnomes, the aforementioned leaf blower, a fire iron, electric candles, lamb shears, a flashlight, props from a costume store, a mirror, and water balloons.
  • Incredible Shrinking Man: In "Little Dipper"
  • Inferiority Superiority Complex: Played With and Downplayed with Dipper, as it doesn't really fool anyone.
    • In "Society of the Blind Eye", Dipper flat out admits that he's playing up his role as the Smart Guy in order to hide his low self-esteem.
  • Inherently Funny Words: Mabel has Rumble McSkirmish say some.
    Rumble: EFFERVESCENT! APPLE FRITTER! RIBOFLAVIN!
  • Insane Troll Logic:
    Stan: You know, studies show that keeping a ladder in a house is more dangerous than a loaded gun. That's why I own ten guns. In case some maniac tries to sneak in here with a ladder!
  • Inside a Computer System: Soos tries to do this by climbing into an arcade machine. The key word being "tries."
  • In-Series Nickname: Soos has a habit of calling Mabel "Ham-bone" and calls the twins "Mystery Twins".
  • Instrumental Theme Tune: It's a nice theme, and somewhat dark to boot.
  • Intergenerational Friendship: The twins and Soos.
  • Invisible Parents: So far Dipper and Mabel's parents.
  • Jaywalking Will Ruin Your Life: In "Mabel's Scrapbook: Heist Movie", Mabel takes a candy bar with her when she and the Pines family go the movies, and because of the "No Outside Food or Drink" rule, [Butt Monkey Thompson]] the overzealous manager has them banned from the theater.
  • Jerk Ass: The Northwest family in its entirety. They lie, cheat, steal and generally abuse their wealth for all it's worth. And just to drive it home, they actually commemorate their assholeish activities with paintings. One such painting shows a Northwest ancestor making some sort of deal with Native Americans, with his fingers crossed behind his back. The only known exception is Pacifica.
  • Jerkass Façade: Pacifica Northwest, of all people.
  • Jerkass Has a Point: Bill Cipher is the first and only person to point out Mabel's selfish behavior whenever she has a new crush (i.e, every week), leading with her allowing him to almost get Dipper's journal.
  • Jerk with a Heart of Gold: Stan, especially after his Character Development finally kicked in. He's a cranky, lazy, stingy old man with a criminal record and a highly questionable moral code, but he still undoubtedly cares about Dipper and Mabel.
  • Journey to the Center of the Mind: The plot of "Dreamscaperers." Dipper, Mabel, and Soos go into Grunkle Stan's mind to prevent Gideon from stealing the safe code from Stan's brain.
  • Just Following Orders: The police didn't really want to haul Dipper and Mabel off to Washington, but they had their orders.
  • Just You And Me And My Guards: Dipper and Robbie decide to settle their differences with a fight. Dipper, being a noodle-armed weakling, enlists the help of martial arts video game character Rumble McSkirmish to scare off Robbie. Unfortunately, Rumble doesn't know the difference between "scare off" and "mercilessly pummel".
  • Kamehame Hadoken: Rumble McSkirmish uses this as a main attack.
  • Karma Houdini: Almost happens to Pacifica Northwest in "Irrational Treasure". The twins found evidence of who actually founded Gravity Falls, but Mabel's willing to let it go. Dipper, however, isn't going to let this happen, and so, at the last second, right before she leaves, he gives her the evidence, which doesn't exactly please her.
    Pacifica: What!? Mom!
    Dipper: Man, revenge is underrated. That felt awesome!
  • Kick the Dog: Once Gideon has control of the Mystery Shack, he treats Waddles very cruelly.
  • Kid-anova: Mabel can't seem to go a week without getting a new crush. Only problem is, most of them end up being dangerous magical creatures in disguise.
  • Kid Detective/Kid Hero: Dipper and Mabel.
  • Kiss Me, I'm Virtual: Giffany in "Soos and the New Girl". Considering the setting of the show, she turns out to be more than she's advertised.
  • Kiss of Life: At the climax of "The Deep End", Dipper has to give Mermando, a merman, "reverse CPR" by spitting several mouthfulls of water into his mouth.
  • The Killer Was Left-Handed: In "Headhunters."
  • Kindhearted Simpleton: Soos, though he's smarter than he looks, is nothing if not kindhearted.
    • Sev'ral Timez, Mabel's "Pet Boy Band" in the episode "Boy Crazy". Considering the fact that they spent their entire life in a hamster cage, their baffling idiocy is pretty understandable, but they're still very sweet and respectful.
  • Latin Lover: Mermando.
  • Large Ham: Mabel can get pretty over-the-top when she wants to.
    • Blendin Blandin gives Lemongrab a run for his money in terms of how much high-pitched ham he can inject into his lines. Fitting, seeing as how they have the same voice actor.
    • Grunkle Stan, what with him being a showman and all. Off the clock, he's a little more subtle, but he still has his moments.
    • Rumble McSkirmish shouts almost every single line he has. He's a fighting game character, he can't help it.
    • All the Lilliputtians in "The Golf Wars", all in their own special way.
    • Mermando sometimes plays up the whole Latin Lover thing a bit too much.
    • Bill Cipher. See Evil Is Hammy.
  • Larynx Dissonance: Grenda.
  • Laughing Mad: Gideon tends to do this, especially in "Little Dipper."
    • Bill Cipher has a maniacal cackle that he frequently breaks out in.
  • Leaning on the Fourth Wall:
    • In "The Legend of the Gobblewonker", Soos is afraid he might be a side character and thus be killed off by the monster first. Obviously, Soos is a side character.
    • At the end of the Cold Open for "Little Dipper", the Pines decide to go watch TV. As they walk offscreen, Mabel cheerfully says "my favorite part is the theme song." Cue the opening and Instrumental Theme Tune.
    • "Little Gift Shop Of Horrors" gives us the following scene that plays while the viewers can only see the characters and shadows of the fight on the wall in the back.
    Stan: Stop Motion is pure evil.
    Soos: And probably really expensive.
    Harry: Incredibly expensive.
    Soos: This is an impressive fight though. Glad I'm facing towards it.
    • In the episode "Boss Mabel", the host of "Cash Wheel" demands the camera man to cut to commercial at the exact moment of the actual show's commercial break.
  • Let's Get Dangerous: Much like how Dipper is often Not So Above It All when things are calm, Mabel has proven that she can be competent both physically and mentally when things get serious.
  • Libation for the Dead: Dipper pours some of his soda on the roof when Tyrone commits unintentional suicide in "Double Dipper".
  • Light Feminine and Dark Feminine: Mabel is the light feminine to Pacifica's dark feminine.
  • Limited Wardrobe: Averted with Mabel's sweaters. Played straight with the other characters.
  • Little Boy Seeks Big Girl: Dipper has a crush on Wendy, a teenager twice his size.
  • Little Miss Badass: Mabel.
  • Living Statue: In "Headhunters".
  • Loin Cloth: In "Dipper vs Manliness" Dipper wears one, together with lots of (fake) tattoos, when the Manotaurs send him to confront the Multi-Bear.
    • In the "Clay Day" segment of "Little Gift Shop of Horrors", one of the stop-motion monsters is called the "Loinclothiclese".
  • Long-Haired Pretty Boy: Mermando. Gabe qualifies as well, as his hair is long enough to make a ponytail.
  • Long-Lost Relative: Stan's twin brother, AKA, the Author. He's been trapped in that portal device in the basement for thirty years until finally being released in "Not What He Seems".
  • Long Title: "Soos' Really Great Pinball Story: Is That A Good Title? Do They Have to Be Like Puns or Whatever?"
  • Lost The TV Remote: Stan's subplot in "The Inconveniencing."
  • Lost World: In "The Land Before Swine", Dipper and the others discover a cavern with live dinosaurs encased in amber.
  • Love at First Sight: Mabel was immediately enamored with Mermando. The same thing occurs with Gabe only that fades when at the end of the episode he passionately kisses the puppets on his hand while opening its mouth to boot.
  • Love Hurts: Dipper's Precocious Crush on Wendy ultimately ends in heartbreak. He's just too young at this point for anything romantic to work out between them, though they still remain friends.
  • Love Makes You Crazy: Lil' Gideon... although he was probably messed up even before he met Mabel.
  • Love Triangle: Dipper and Robbie both vie for Wendy's attention, with both succeeding and failing at different times.
  • Lying Finger Cross: In the episode "Fight Fighters", Mabel makes a promise to Grunkle Stan and puts on a sweater with a hand doing the "Scout's honor" gesture on the front. When she turns her back to the fourth wall we see the back of her sweater has a hand with its fingers crossed.
    • Both Stan and Dipper do it when promising to at last be more honest with each other, even though they don't quite trust each other anyway.
  • The Mad Hatter: Bill Cipher
    Bill: Sure I am, what's your point?
  • The Magazine Rule: The characters have some interesting magazine subscriptions, such as Wendy's Indie Fuzz and Lake Ranger McGucket's Stoic Monthly.
    • Dipper finds a chest full of magazines in Stan's room featuring nothing but pictures of women in full dress and one-piece wetsuits, which he finds disgusting but also somewhat confusing.
  • The Makeover: The girls try to give one to Dipper while having a sleepover. Also, Mabel gives "Flash Makeovers" to various characters in the "Mabel's Guide to Beauty" short.
  • Mama Bear: Soos' grandmother, in regards to his deadbeat dad.
  • Man Child: Soos. He's even described this way in Disney Channel's official promotions.
    • In "Soos and the Real Girl", he gets a girlfriend who goes about life similarly.
  • Marry Them All: In "The Love God", Mabel is shown a vision of all of her ex-boyfriends as a distraction. Dipper is frustrated to see that it's working, and that she's attempting to marry all of them.
  • Mars Needs Women: G-Rated version with Mabel and the gnomes.
  • Masked Luchador: Soos dresses as one for Summerween.
  • Masquerade: Invoked by the Blind Eye Society, who wipe the minds of anyone who sees anything supernatural, including themselves from time to time. Their memories of the society are erased by the Mystery Shack crew. While this means the Masquerade is no longer actively held, the Society's usage of the memory wiper has caused brain damage among most of the townsfolk.
  • Meaningful Echo: When the police ask The Cute Biker what to do with Gideon in "Gideon Rises" he simply says "Get 'im" with tears in his eyes.
  • Meaningful Name:
    • In "Double Dipper", we learn that Dipper's name is a take on "The Big Dipper", which he has as a birth mark on his forehead. We also learn that it's just his nickname (his real name is yet to be revealed).
    • In "Not What He Seems" Gravity Falls, already a Punny Name, also becomes this due to the Gravity Screw from Stan's portal.
  • Medium Blending: The "Clay Day" segment from "Little Gift Shop of Horrors" works in a lot of Stop Motion claymation, along with a picture of intentionally horrible CGI.
    • The credits of "Sock Opera" features live-action puppetry.
  • Meet Cute: Soos and Melanie in "Soos and the Real Girl." He even meets her during her shift at a restaurant called "Meat Cute!"
  • Memory Wiping Crew: The Blind Eye Society.
  • Message in a Bottle: This is how Mermando keeps in touch with Mabel.
  • Messy Pig: Waddles was seen rolling in the mud once, but he's usually very clean, just like real pigs.
    Soos: A mud puddle... do I dare live out the cliche? (pauses, then dives right in)
  • Mighty Lumberjack: Manly Dan.
  • Mind-Control Music: Used by Robbie in "Boyz Crazy".
  • Mind Rape: Looking into a Gremloblin's eyes will reveal your worst nightmare.
    • Bill Cipher's nightmare ray, which he unleashes on the protagonists after they anger him in "Dreamscaperers" has a similar effect.
  • Mind Screw: In "Not What He Seems", the twins discover a stash of newspapers in Stan's room telling them that Stan was actually killed in a car accident thirty years prior to the start of the series, and the Stan that the twins are living with is actually a grifter who assumed his identity. Except he couldn't be; even if you're a professional conman like Stan, you simply can not assume the identity of somebody legally recognized as dead and live out their life without people questioning you. And furthermore, we've seen him while alone in his secret lab, where it's clear that he does legitimately care about the twins like they're his own family. And if he really is an impostor and not the twins' great uncle, how does this tie in with later reveal that his twin brother is the author? Did they swap identities somehow? Does it have something to do with that portal device? Is the "Stan Pines" the newspaper was referring to even the right Stan, assuming the fan interpretation that his brother's name is Stanley is correct? Guess we'll just have to keep our brains from falling out until the next episode...
  • Misery Builds Character: Which is why Stan is so hard on Dipper.
  • Misplaced Wildlife: Averted for the most part. Other than the alligators briefly seen in "Dipper vs. Manliness", every real-world animal shown in Gravity Falls is native to Oregon.
    • A wolf is seen gnawing on Dipper's leg in "Carpet Diem", though it could have just been a coyote. note 
    • All the bears on the show have been grizzlies, despite only black bears living in Oregon today.
    • Cleverly subverted in "The Time Traveler's Pig": when the twins briefly travel back in time to the pioneer days, they get chased by a stampeding herd of bison. Bison are not currently found in Oregon, but they were back in the 19th century before hunters killed most of them off.
    • "Land Before Swine" showed amber-preserved Spinosaurus (possibly, only its tail and part of its sail was seen). Spinosaurus lived in Africa.
  • Missing Mom: Wendy's mother is "sadly, no longer with her".
  • "Mister Sandman" Sequence: Although not a time-travel example, in the first few moments of the episode "Irrational Treasure," the Pines family is bombarded with covered wagons, butter churns, livestock, old-timey speech mannerisms, and banjo music, because it's Pioneer Day (to Stan's horror). There is also an excessive number of woodpeckers, but that's a historical marker unique to Gravity Falls.
    • When Dipper and Mabel flash through various eras in "The Time Traveler's Pig," one such escapade includes heading to "Ye Old Oregon Trail," as announced by the driver of a covered wagon over a treacherous cavern's edge; he also mentions to his wife "Fertilia" that she must have popped out two more children when he wasn't looking.
    • Played with in "Boyz Crazy," when Grunkle Stan reminisces about his youth — cut to "The Juke Joint," complete with neon lighting, jukeboxes, corny signs, and cherry-on-top milkshakes, plus a young "bad-boy" Stan dressed to resemble James Dean. It's not a 1950's diner, though (Stan isn't old enough for that), but rather a 1970's diner themed to resemble the 1950's. As further proof, Stan's girlfriend wears 1970's-style hot pants, and later falls for a hippie guitarist.
  • Misunderstood Loner with a Heart of Gold: The Multi-Bear in "Dipper vs. Manliness".
  • Moment Killer: Grunkle Stan unwittingly interrupts a man who is about to propose to his girlfriend, and proceeds to tell a joke about how awful marriage is.
  • Motion Capture Mecha: The method Gideon uses to control his giant robot in the first season finale. Wearing an actual motion capture suit, no less. Proves to be its downfall when Dipper punches Gideon with his own hand, making the robot do the same.
  • Muggles: Most of the residents of Gravity Falls seem either unaware of the supernatural occurances, or they're Genre Savvy enough to know when to strike. When others are Dangerously Genre Savvy to the paranormal, like Gideon, they're often antagonists.
    • In the episode "Society of the Blind Eye", we find out that this isn't a coincidence or typical cartoon-townfolk obliviousness; everybody in town is being systematically given Laser-Guided Amnesia by the titular secret society.
  • Mundanger: Sort of, in Not What He Seems. While there is a giant portal that could very well cause The End of the World as We Know It in Stan's basement motivating the plot, it's not technically the biggest threat. The biggest threat would be the FBI agents adhering to proper protocol at times like this, getting children out of a bad situation and arresting a known criminal... which, given the portal and its possible consequences, comes across as Be as Unhelpful as Possible.
  • Mushroom Samba: In Episode 5, Mabel goes through one after eating a banned candy product.
  • My Friends... and Zoidberg: In "Double Dipper", Gruncle Stan addresses the staff for the party as "Party People...and Dipper".
  • Myth Arc: Three seasons have been fully planned out, including a cliffhanger in the first season's finale.
  • Naked People Are Funny: Stan in both "Summerween" and "Boss Mabel." Unfortunately.
  • The Needless: Bill Cipher, at least conceivably. He's shown to have no understanding of the concept of needing sleep and, unless he's inhabiting a body, can't experience tactile sensations.
  • Nerves of Steel: During "The Inconveniencing", Wendy is the only character who doesn't panic once (she's scared, but she can still think straight). Shown off again in "Into The Bunker", where she remains relatively cool headed the entire time she is under the attack of The Shapeshifter, even taking the time to bind up one of her injuries.
  • Nervous Wreck: Blendin Blandin.
  • Never Learned to Read: Deputy Durland.
  • Never Say "Die": Averted.
    • And kicked to the curb with Episode 5.
  • New-Age Retro Hippie: One once came between Stan and Carla.
  • Nice Guy/Girl: With the exception of Stan, who's much more of a Jerk with a Heart of Gold, every major character on the show is a very nice person. Flawed, but nice. See the character page for more specifics.
    • You kind of have to be if you want to stay sane in a town crawling with supernatural evil. That said, not every supernatural creature is horrible:
      • The Multibear is pretty darn amiable for a bear with several dozen heads. It's enough to convince Dipper to give up his task of killing him.
      • Mermando, while a bit strange, is a genuinely kind young merman. He's by far the most pleasant of Mabel's crushes, and even got the honor of giving her her first kiss.
      • Sev'ral Timez, despite being... dim, are all very kind to Mabel and her friends once they rescue them.
  • Nice Hat: Grunkle Stan really likes his fez. Dipper also gets his hat by the end of the first episode.
    • Then there's Bill Cipher's top hat.
    • Dipper's pine tree cap, which he got in the first episode after his old one was eaten by a gnome.
    • Wendy's bomber hat.
  • Nice Job Fixing It, Villain: Bill Cipher at the end of "Sock Opera". With one hand on the Journal and Mabel at his mercy, he decides to mock the idea of making a sacrifice for one's sibling, giving Mabel a reason and a chance to attack him.
  • Nightmare Fuel: In-universe, Mabel's "Bear-O" puppet from "The Tooth", which is capable of bringing other children to tears within seconds. Even Dipper finds it unsettling.
    Dipper: No, creepy. Bear-O's creepy, everyone hates Bear-O.
    • Invoked again with the disturbing broken-down "nugget maker" Ol' Goldie, which now does nothing more than rattle violently, emit a piercing scream, and leak oil out of its mouth. Wendy nervously suggests getting rid of it, as it reminds everyone of "the inevitability of death". Even Stan is terrified when it bites down suddenly on his arm.
    • Mabel is shown to have an intense fear of stop-motion and Claymation creatures. Eventually, after learning that it's all created with dark magic, she cheerfully considers this phobia justified, ironically getting over it somewhat.
  • No Communities Were Harmed: The fictional town of Gravity Falls, Oregon was probably inspired by many local landmarks/tourist traps from both Humboldt County, California and southern Oregon. According to the map in the first episode, however, Gravity Falls should be located somewhere in the Cascades.
  • No Fair Cheating: The Tumbleweed Terror pinball game really does not want you to tilt it.
  • No-Holds-Barred Beatdown: Dipper and Gideon in "Gideon Rises". Dipper wins.
  • Non-Standard Character Design: A few examples.
    • Rumble McSkirmish from the episode "Fight Fighters" is a video game character brought to life, and as such is rendered as 16-bit pixel art reminiscent of Street Fighter.
    • There's also Xyler and Kraz who look like they're straight from an 80s cartoon than the original designs from the show.
    • The Boy Band Sev'ral Timez are also the only characters in the series so far with visible blue irises in their eyes instead of just pupils.
    • Giffany has a very Animesque design, since she's meant to invoke the image of a character from a Japanese Dating Sim game.
  • Noodle Incident:
    Bud: It's imported from Co-lom-bia.
    Stan: Wow, I went to jail there once!
    • Also, George Washington had to have some motivation for spanking Quentin Trembly with a paddle for three hours.
    • This exchange between Soos in Waddles' body and a hungry Old Man McGucket:
    Soos-In-Waddles: DON'T EAT ME! I'M A MAN TRAPPED IN A PIG'S BODY!
    Old Man McGucket: That's what they all say...
    • When the Mystery Shack crew discuss past encounters with Gideon:
    • Possibly one implied in "Bottomless Pit":
    Mabel: [playing 'Spin-the-Pig'] Hey, Grunkle Stan, ever kissed a pig before?
    Stan: I'm not gonna answer that question.
    • In "Carpet Diem", Soos and Waddles switch bodies. During this time, something happened that caused Waddles-as-Soos to romance and then propose to a random woman that Soos had never met before. He was understandably very confused when the switch was reversed.
    • Stan mentions another in "Blendin's Game". Apparently, he petitioned the US Government to have July 13th removed from Calendars as a favor to Soos. This somehow led to him being declared a flight risk, and Stan is now no longer allowed on airplanes.
    • According to Mabel, something happened between her and a vampire that she only ever mentions in one off-hand comment. Dipper notes that he doesn't remember that, and she informs him that she doesn't tell him everything. Whether this happened or whether she's just making things up based on her Twilight-inspired obsession, though, is hard to know.
  • Noodle Implements: The cure for zombification.
    Dipper (reading from journal): It's gonna take a lot of formaldehyde.
    Mabel: Ooh, and cinnamon.
  • No Peripheral Vision: Rumble has no "looking up" animation.
    • Inverted with the pterodactyl baby, which has nothing but peripheral vision. This is exploited for the group to escape from it.
  • No Snack For You: Happens briefly in "Blendin's Game". Soos teaches them how to get around the problem, leading to a Stable Time Loop when Mabel goes back in time to teach him the same trick.
  • Not So Above It All: Dipper may be the Straight Man to Mabel, but there have been many, many times where he joins in on her silliness with a smile on his face.
  • invokedNo Yay: This is how Grunkle Stan reacts to him and Soos having an akward moment in "Golf War".
    Soos: (Lying next to him, shirtless) There sure are a lot of stars out tonight...
    Stan: Welp, this is getting weird. (Gets up and leaves)
  • No, You:
    Mabel: Grunkle Stan, why you ackin' so cray-cray?
    Stan: You're the one who's ackin' cray-cray!
  • The Nose Knows: Mabel can tell when Robbie's coming by the smell of his anger and hormones.
  • No Smoking: In "Headhunters" the wax model of Groucho Marx isn't holding his signature cigar. Lampshaded by Groucho as he's killed.
  • Nothing Is Scarier: Played for Laughs in "Dipper vs. Manliness", as we never find out exactly what is in the Pain Hole that makes it so painful.
  • Nothing Is the Same Anymore: The ending of "Dreamscaperers". Subtler examples are prevalent, since the linear continuity of the series means that changes that aren't resolved visibly are likely to remain permanent, and sometimes have significant effects in later episodes (including the lampshaded example of Mabel winning Waddles, who becomes a major supporting character).
    • "Not What He Seems". Stan is now wanted by the highest branch of the US Government, his work on his portal device finally concludes and partially destroys the entire town, the twins and Soos finally discover the secret basement, Stan's mysterious past is starting to leak through the cracks, it's revealed that the real Stanford Pines died in a car accident thirty years previously and somebody has been taking his place this entire time, and we finally know what was waiting on the other side of Stan's portal - his twin brother, The Author.
  • Not-So-Harmless Villain: Gideon.
  • Not-So-Phony Psychic: Gideon.
  • Not What It Looks Like: When Mabel in Dipper's body spies on Dipper (in Mabel's body), Candy and Grenda reading romantic novels through a key hole, Stan comes by and thinks Mabel is "at that creepy age when he spies on girls" and decides to give her The Talk.
  • Obstructive Vigilantism: In "Bottomless Pit", Dipper and Mabel both eventually feel that lying to the police is "for the greater good."
  • Occult Detective: Both of the twins, but Dipper especially.
  • Odd Friendship: The twins and Soos.
  • Off Model: Mabel here.
    • In the first episode, Dipper suffers from 2 cases of this - in a row! In the first one, Dipper has 3 arms instead of 2, and in the second one, he has 4 arms!
  • Older Hero vs. Younger Villain: Stan, a man old enough to be a great uncle vs Gideon, a psychopathic child.
  • Old-Fashioned Rowboat Date: Gideon takes Mabel on one.
  • Ominous Owl: Owls appear to be a reoccurring motif, as an owl or the image of one usually appears at least Once an Episode. A Freeze-Frame Bonus in the "Stan's Tattoo" short gives us some text that reads "All secret societies worship a hyper-intelligent barn owl named Duane 'The Enforcer' Roosevelt. Most meetings consist of saying the secret oath, dressing in robes, hooting, gluing owl feathers to their skin, and devouring gophers whole in honor of their beloved barn owl overload. But not all secret societies worship barn owls, some of them worship western screeching owls. Also: Other owl-related jokes. In addition: Owls, owls, owls, owls, owls. And remember, when you don’t know where else to turn just ask yourself: 'What would Duane Do?' Which is: Use your creepy heart-shaped face to see your prey, swoop down from a tree, eat an adult male vole, then cough up his bones into a disgusting ball that kids will later open in a high school biology class."
  • One-Gender Race: The gnomes.
  • One of the Boys: Wendy, to the point where she refers to everybody as "buddy" or "dude", even Mabel. Given her upbringing, it only makes sense.
    Dipper: (Reacting to Mabel's annoying obsession with a band) Ugh, girls.
    Wendy: I know, right?
  • One of the Kids: Soos.
  • Only Known by Their Nickname: Dipper, after the Big Dipper-shaped birthmark on his forehead.
  • Only Sane Man: Downplayed, but Dipper's companions rarely taken him as seriously as they ought to.
  • One Scene, Two Monologues: The conversation between Wendy and Mabel in "The Hand That Rocks the Mabel."
  • OOC Is Serious Business: In "The Society of the Blind Eye", when Mabel is feeling bummed out about her failed summer romances, Wendy first catches on by noticing that she walked by a cat and didn't pet it.
    • A more subtle, Played for Drama example is in "Boyz Crazy": Wendy has always been One of the Boys, and earlier in the same episode, she even leveled with Dipper and casually admitted that girls can be annoying. So, when Dipper reveals that her boyfriend Robbie has been trying to brainwash her, and Dipper immediately tries taking advantage of their breakup, her reaction makes it perfectly clear that he really screwed up:
    Dipper: Um, hey! Uh, now that your night is free, me and Grunkle Stan are thinking, maybe bowling, or something?
    Wendy: (tearing up) Are you serious?! Right now? Ugh! What is wrong with guys?! You only think about yourselves!
    • Mabel is perpetually optimistic and nearly always happy, but she's dynamic enough that she still gets upset at things like most people would. Seeing her actually cry, however, is reserved only for the most critical of circumstances, like, say, the entire universe being seconds away from destruction.
    • If Stan ever takes off his Fez, somebody is about to receive a beatdown.
  • The Other Rainforest: Gravity Falls is in the middle of Oregon. According to the map in the first episode, it would be somewhere in the Cascades.
    • The map from the first episode also includes a few actual Oregonian towns and locations, including Medford, Corvallis (mispelled as "Corvalis"), La Grand, and Mt. Hood
  • Our Cryptids Are More Mysterious: Some cryptids appear alongside more traditional fantasy creatures.
  • Our Demons Are Different: Bill Cipher, to the point where there's some ambiguity as to whether he actually is a demon. Granted, he was brought to Gravity Falls via a Summoning Ritual and displays most of the powers you'd expect (Deal with the Devil, Demonic Possession, Playing with Fire, etc.), but his appearance, personality, and general demeanor aren't really comparable to... well, anything.
  • Our Ghosts Are Different: They seem to be virtually omnipotent within the place they haunt.
  • Our Gnomes Are Weirder: They seem to be a One-Gender Race who need to find a human girl to be their queen. Also, they vomit rainbows and can join together to make a giant monster.
    • Jeff is also seen taking a bath of running squirrels, though it's unclear whether it's an actual gnome thing or just Jeff himself who is into that sort of thing.
  • Our Goblins Are Different/Griping About Gremlins: The Gremloblin, which is half-and-half.
  • Our Mermaids Are Different: They apparently go through puberty quite early and have seventeen hearts ("Horrifying but true!") They're actually pretty standard otherwise.
  • Our Monsters Are Weird: The Mulitbear and the creature in the convenience store freezer.
  • Our Slogan Is Terrible: Greasy's Diner, "We have food".
    • Stan Vac, "It sucks more than anything".
  • Our Time Machine Is Different: It looks like a tape measure.
  • Our Zombies Are Different: They're fairly standard, if a bit frightening, except for two things: one, they appear to be summoned out of some kind of Hell-portal instead of just coming out of the ground, and two, being bitten by one doesn't affect your personality in the slightest, it just makes you crave human flesh.
  • Out of Order: A bizarre case where the production order is off but the airing order matches the writing order. note 
  • Outright Lie: Grunkle Stan tells the police that he needs a seeing-eye bear, producing a phony note from "Dr. Medicine" written on the spot. They buy it.
  • Overly Long Gag: The credits gag from the pilot, the entirety being a gnome vomiting rainbows on an endless loop.
    • Also, the credits from "Double Dipper," with Soos pressing every sound effect on the keyboard.
    • And then in "Bottomless Pit," the entire credits gag is Stan falling with an annoyed expression on his face.
    • Rumble's combo on Dipper.
    Narrator: SUPER POWER NINJA TURBO NEO ULTRA HYPER MEGA MULTI ALPHA META EXTRA UBER PREFIX... COMBO!!!

    P - Z 
  • Papa Wolf: Despite not actually being their papa, Stan does not take it well when his great niece and nephew are threatened.
  • Parental Bonus: Loads. So much so that it's considered one of the most Parental Bonus-ridden shows Disney has aired in a long, long time. See Getting Crap Past the Radar and Shout-Out for more details.
  • Parental Substitute: Stan became one of these for Soos after his dad skipped town on him.
  • Perpetual Smiler: Mabel. Whenever she stops smiling, it means that the shit has really hit the fan.
  • Pet the Dog: Grunkle Stan gets a moment like this after feeling guilty for insulting Dipper and Mabel and lets each of them take anything they want from the Mystery Shack. In true Grunkle Stan fashion, he tells them to do it before he changes his mind. He also saves Waddles because he wants Mabel to talk to him again and in "Dreamscaperers" when we find out why he's so tough on Dipper.
  • Phoneaholic Teenager: Tambry
  • Pinball: Featured in "Soos' Really Great Pinball Story".
  • Pink Girl, Blue Boy: Dipper wears a blue and white hat and a blue vest; Mabel isn't as consistent but frequently wears pink/purple/red clothes.
  • Pint-Sized Kid: Every kid in the series, major and minor. It makes Dipper's Precocious Crush on Wendy seem more unnatural than it actually is.
  • Plucky Girl: Mabel.
  • Pointless Bandaid: Old Man McGucket has one on his beard.
  • Pokémon Speak: Shmebulock the gnome.
  • Polar Opposite Twins: Smart and conventional Dipper and energetic optimist Mabel. This image best shows their dynamic.
  • Police Are Useless: Constantly. They actually make the Springfield police look competent.
  • Police Code for Everything: An officer about to fit a cantaloupe in his mouth is a "23-16", and a citizen delving into the true story of the town's origin is a "Code Sepia".
  • The Pollyanna: Mabel often verges on this, but the first true example is during the episode "Not What He Seems". Throughout the entire episode, he simply will not accept the possibility that Stan is hiding villainous intent from them, despite the evidence continuing to pile up more and more as the story goes on. She very nearly breaks during the climax, but in the end, it's her optimism and faith that saves them all.
  • Pool Scene: "The Deep End" is a whole pool episode.
  • Poor Communication Kills: A lot of the drama during "Not What He Seems" could have been avoided if Stan simply explained what the portal is supposed to do.
  • The Power of Love: Or, the Power of Mabel.
  • Pre Ass Kicking One Liner: Mabel has one in "Sock Opera":
    Bill Cipher!Dipper: Who would ever sacrifice everything they've worked for just for their dumb sibling?
    Mabel: Dipper would.
    • Soos has one in "Soos and The Real Girl" Just as he's about to throw the CD which keeps Giffany alive into a burning oven.
    Soos: Game over, Giffany!
    • Stan gets his turn in "Not What He Seems" after he is taken in by the government.
    Agent Powers: Sorry, but you've got a flight to catch.
    Stan: Oh yeah? So do you. *Cue gravitational anomaly*
  • Precocious Crush: Either Subverted or Downplayed with Dipper's crush on Wendy. He's 12 and she's 15, making them only three years apart from each other. Though for the time being, those three or so years are still too much.
  • Properly Paranoid: The old coot was right to be worried about the wax figures.
    • The FBI is correct in believing that Stan has built a doomsday device. However, Stan doesn't want to use it to destroy the world, but to save his brother.
  • Psychic Powers: Li'l Gideon. Until Mabel destroyed his amulet.
  • Ptero Soarer: The "pterodactyl" from "Land Before Swine", which looks like an unholy mixture of all stereotypes, down to the scaly skin, being called a "dinosaur", having eagle-like hindlimbs, leathery wings, having a Pteranodon crest alongside rather mismatched teeth, making chicken-like nests and having zero to no body fat. Strangely enough, though, it walks quadrupedally, like a real pterosaur.
  • Pun-Based Title:
  • Punch Catch: Dipper catches Gideon's fist during their fight in "Gideon Rises". He then twists his hand around and punches Gideon with his own fist.
  • Punny Name:
    • Gravity Falls itself.
      • Lampshaded; it was discovered and named after its true founder rode over a cliff.
    • The Gravity Falls gossip reporter is named "Toby Determined".
    • The waitress's name is "Lazy Susan". On the surface, she's called this because she has a lazy eye and is named "Susan", but it can also refer to a table surface that spins.
    • Pacifica Northwest.
    • Rumble McSkirmish.
    • Any and all of the Manotaurs, except for Beardy.
    • Mermando is, of course, a merman.
    • Bill Cipher (he's on the dollar ''bill'', geddit?)
      • It's also possible that his name is a play on the Beale Ciphers.
    • Gideon Gleeful
  • Questionable Consent: One point of contention with the episode "The Love God" is over whether or not Mabel using a love potion to make Robbie and Tambry start dating was ethical. See Headscratchers for more details.
  • Raptor Attack: The raptor from "Land Before Swine". Like the Ptero Soarer from the same episode it is guilty of possessing all pop-culture stereotypes: oversized, lack of feathers, pronated hands, and reptilian eyes. It also has two-fingered hands, a feature that doesn't correspond to any known deinonychosaur.
  • Rapunzel Hair: Mabel, Wendy and Pacifica all sport hair that reaches below their waist.
  • Rated M for Manly: The manotaurs are a race of Always Male half-man half-bulls devoted to this trope. Goes into Testosterone Poisoning territory.
  • Real After All: At the end of "Legend of the Gobblewonker," Dipper's camera falls overboard and we get a shot of the real Gobblewonker.
  • Reality Warper: In "Dreamscaperers", Dipper discovers that he can do anything he can imagine while inside a dream.
  • Reality Ensues: As it turns out, Wendy knew Dipper liked her all along because she could hear him muttering things about it under his breath. While he was right next to her.
    • When Gideon takes over the Shack, Stan's awesome battle plan is... to send the twins back home because he can't take care of them anymore. "Summer's over," as he puts it.
    • Also, after Stan beats a horde of zombies back to death and bursts into the barricaded attic, his first words are "Auugh- everything hurts."
    • When Stan gets arrested in "Not What He Seems", where are the twins taken? Child services. No wacky relative, no vague "you're gonna stay with us", their destination is explicitly identified as "child services".
  • Really Gets Around: G-Rated example, but Wendy definitely has a hefty list of ex-boyfriends, considering she's only 15.
  • Recurring Extra: The cute biker.
    • The goat and the woodpecker.
      • Everyone who lives in Gravity Falls, like Lazy Susan, Wendy's friends, Toby Determined, and Manly Dan, to name a few.
  • Redhead In Green: Wendy.
  • Red Herring: Both Manly Dan and Toby Determined in "Headhunters." Also, The Laptop in "Into the Bunker" and "Sock Opera".
    • There were so many hints dropped that Old Man McGucket is the author of the journals that a good number of fans accepted it as canon. He's not, he just worked with him.
    • "Northwest Mansion Mystery" heavily implied Bill Cipher was behind an impending calamity. At the end of the countdown, he's nowhere to be seen.
  • The Reveal: In "Not What He Seems", we finally find out who the author of the journals is; it's Stan's brother.
  • Ridiculously Cute Critter: Mabel's beloved pet pig, Waddles.
  • Rich Bitch: Pacifica Northwest. Turns out the "bitch" part is just an act.
  • Right for the Wrong Reasons: Dipper thinks that Mabel's new boyfriend isn't normal and he's a zombie. He was right that Norman isn't normal, but he's actually a bunch of gnomes.
  • Ring Around the Collar: Mabel always wears some colorful turtleneck sweater, whose oversized collar obscures most of her neck. Dipper's vest has its collar turned up, which serves a similar effect, even though more of his neck is visible.
  • Rivals Team Up: Mabel and Pacifica team up against the Lilliputtians in "The Golf War".
  • Room Full of Crazy: Downplayed when McGucket's memories are finally exposed. The room he's seen standing for most of them gradually gets more and more demolished as his Sanity Slippage progresses, with the words "HELP ME" eventually showing up in (hopefully) red paint. It's the only one shown, but it's very big and we don't get to see very much of the room, implying this trope.
  • Rubik's Cube International Genius Symbol: The "What-The-Heck-A-Hedron" is essentially a very hi-tech Rubik's Cube, from the makers of "Stresseract" and "Annoyangle". it eventually gets solved by a hyperintelligent Waddles.
  • Running Gag: There are a couple of potential running gags, like Grunkle Stan being unable to find his pants and Manly Dan beating something up while the Cute Biker cheers him on.
    • We have:
      • Dipper dropping ice that he gets for Wendy.
      • Dipper's hat catching fire.
      • Woodpeckers.
      • The Dipper and Mabel look-alike kids.
      • Effigies of Grunkle Stan getting destroyed, usually through burning.
      • Someone describing what they are doing in a sing-song voice.
    Soos: Doo doo doo, walking to my car~ (2x05)
    Stan: Putting a rainbow wig... On a big white gorilla~ (2x09)
  • Rushed Inverted Reading:
    Stan: Whatcha readin there slick?
    Dipper: (hides the journal and grabs a magazine) Oh, I was just catching up on-"Gold Chains for Old Men Magazine?"
    Stan: That's a good issue.
  • Sarcasm-Blind: Mabel and Soos have both displayed shades of this trope.
  • Sassy Black Woman: Not a literal case of this trope, but after Grunkle Stan drinks the voice altering potion he ends up sounding like one.
  • Satellite Character: The cute biker started off as one to Manly Dan.
  • Savvy Guy, Energetic Girl: Dipper and Mabel, respectively.
  • Saying Sound Effects Out Loud: Mabel does this on a fairly regular basis, as do other characters.
    • "Tourist Trapped":
      Dipper and Mabel, during their "awkward sibling hug": Pat, pat.
    • "Dipper vs. Manliness":
      Stan: Tap, tap.
      (later) Lazy Susan: Wink!
  • Scenery Porn: It's especially evident in the opening theme, but Gravity Falls is beautiful.
  • Scooby-Doo Hoax: Played straight in Episode 2, with the Gobblewonker. Even this straight example is subverted in the final moments of the episode suggesting that there really is a creature, but it just hasn't been seen (yet?). Otherwise averted in most other episodes, with the monster or ghost proving to be very, very real.
  • Screw Politeness Im A Senior: Grunkle Stan, all the way.
  • Secret Circle of Secrets: The Blind Eye Society. They have the ability to erase people's memories, and they're the main reason everybody in town is so ignorant to all the unusual happenings going on.
  • Security Blanket: Sweater Town.
    • In "The Time Traveler's Pig", Robbie closes his hoodie over his face and continues moping around the fair that way in the timeline where Dipper successfully wins the stuffed panda/duck for Wendy
  • Selective Enforcement: Blubs and Durland will ignore a man snatching an old lady's purse right in front of them, but are quick to respond to reports of excessive giggling.
  • Self-Serving Memory: In "The Land Before Swine", when Stan tells Mabel how the pterodactyl managed to steal Waddles, the details were somewhat off.
  • Sense Freak: Bill becomes one in "Sock Opera", with a focus on pain because he finds it "hilarious!".
  • Sensitive Guy and Manly Man: Dipper is the sensitive guy to Grunkle Stan's manly man.
  • Serious Business: Mr. Poolcheck puts a lot of angry violent determination in making pool time safe. He, and a bar of angry men, also don't take kindly to prank calls.
  • Set Right What Once Went Wrong: In "The Time Traveler's Pig" Dipper tries to win a toy for Wendy at the fair, while at another stall Mabel delightedly wins Waddles the pig. Unfortunately Dipper only succeeds in hitting Wendy in the eye with a ball, causing her to go off with Robbie. After obtaining the time machine Dipper makes several attempts to return to the past and prevent the accident, only for it to keep happening in different ways. Eventually Dipper figures out how to make the ball miss Wendy and hit the target, but Mabel has to be there to help him, so she isn't there to win Waddles and Pacifica wins him instead. Seeing how unhappy this makes Mabel, Dipper realizes he has no choice but to go back and restore the original timeline.
  • Sheet of Glass: Parodied in "Legend of the Gobblewonker," when they fly through a pane of glass held between two boats on a lake.
  • The Sheriff: Sheriff Blubs.
  • Ship Sinking:
    • Wendy breaking up with Robbie in "Boys Crazy" is one. It sunk even more after "The Love God", in which Robbie became an Official Couple with Tambry.
    • In the episode "Into The Bunker," Dipper manages to somewhat to confess to Wendy, who knew it all along and while being flattered, lets him down easy to continue being friends. The sinking cements itself in "Blendin's Game" when Dipper realizes (from the other side of their age gap, due to time travel) just how awkward the whole thing might have been to Wendy.
    • Those who were fond of Mabel/Mermando felt their hearts sink when "Society of The Blind Eye" revealed that Mermando is forced into an arranged marriage with a manatee princess for political purposes. Memando himself is clearly unhappy about this based on the photo sent.
  • Ship Tease: Candy hanging on to Dipper after the Trickster's threat in "Summerween" was enough to send some shippers into fits of squeeing. There were already Candy/Dipper shippers before, but this was the first real interaction that was remotely shippy they could latch onto, with the subtle peek that Mabel would have tried this with them, might just get larger.
    • A lot between Dipper and Pacifica in "Northwest Mansion Mystery", especially the part when she hugged Dipper out of joy when they sealed the ghost within the mirror. Their reaction afterwards sells it.
  • Shirtless Scene: Dipper in "Dipper vs. Manliness."
    • Soos takes off his shirt rather often, and in "Stan's Tattoo", he tries to get Stan to do the same. Stan is disgusted.
  • Shout-Out: Has its own page.
  • Shovel Strike: Soos gives a shovel to Dipper in the first episode when Dipper races off to save Mabel from the gnomes. He also gives him a baseball bat in case he sees a pinata.
  • Show Within a Show: Many, including Duck-Tective, Tiger Fist, Why You Ackin So Cray-Cray?, Baby Fights, Cash Wheel, and World's Most Terrifying Skydiving.
  • Shown Their Work: The Scenery Porn of the opening scene, as well as many of the show's backgrounds, is very accurate to actual Oregonian landscape.
    • Similarly, almost every real-life animal seen living wild in Gravity Falls is actually native to Oregon, including the somewhat obscure purple finch. See Misplaced Wildlife for exceptions.
    • The goat that lives near the mystery shack has rectangular pupils, just like goats in real life.
    • In Northwest Mansion Noir/Mystery, the mudslide that killed the lumberjack was the result of the deforestation that ensued from him building the Northwest mansion . Deforestation can cause mudslides, because the lack of trees destabilizes the soil, so whenever it rains in a treeless era, the ground becomes saturated and slides.
    • For all the stereotypical paleontological inaccuracies present in "Land Before Swine", the episode did get quadrupedal pterosaurs right and portrayed Ceratosaurus with laterally-flat horns.
    • The beavers from "Legend of the Gobblewonker" have yellowish teeth like real beavers.
  • Shrink Ray: Dipper makes one out of magic crystals and a flashlight.
  • Sibling Seniority Squabble: According to Word Of God.
  • Signs of Disrepair: The Mystery Shack's sign regularly loses the second "S" to spell out "Mystery hack", including in the opening theme. Rather fitting considering Grunkle Stan's personality.
  • Single-Target Sexuality: Dipper seems to only have eyes for Wendy, though it's justified since his Limited Social Circle makes her the only girl he hangs out with for any length of time other than his sister.
    • Though, in the episode "Little Mystery Shop of Horrors", he first gets interested in trying to solve the What-The-Heck-Ahedron when he finds out that anyone who solves it apparently gets their picture taken and a kiss from a hot chick. Then again, that episode's canonical status is up to debate.
    • This is up to debate due to ambiguity, but it's a possibility that this trope has gotten averted what with the vague hints that Dipper may be starting to feel something towards Pacifica in "Northwest Mansion Noir".
  • Sitcom Arch-Nemesis: Robbie to Dipper, Pacifica to Mabel, Gideon to Stan. Though Gideon eventually becomes the Big Bad of the first season, and Pacifica and Mabel have settled their differences.
  • Skeleton Key: The President's Key can open any lock in America.
  • The Slacker: Wendy Corduroy.
  • Slapstick Knows No Gender: Just because Dipper is our resident Butt Monkey doesn't mean any of the other characters are safe.
  • Sliding Scale of Comedy and Horror: Interestingly enough, the show shows shades of the comedy dominant variety. While the show mostly treats itself like a straight-up comedy, the premise of each episode frequently deals with the supernatural, with some containing scenes so creepy that you have to check periodically that you're watching a Disney show.
  • Slumber Party: Mabel has one with Candy and Grenda in "Carpet Diem".
  • Smitten Teenage Girl: Mabel, with every Guy of the Week that comes along.
  • Smoke Out: Grunkle Stan's preferred exit method.
  • Socially-Awkward Hero: Dipper, especially in comparison to his sister.
  • Someday This Will Come in Handy: When Dipper finds the book in the first episode, he sees an amulet but ignores it and continues flipping through the book. Later on, in the fourth episode, it is revealed that the amulet grants the wearer mystical powers. Dipper hasn't realized this yet, however.
  • Something Only They Would Say: A physical variation. When Wendy is wrestling against a shapeshifter disguised as her in the climax of "Into the Bunker," Dipper asks for a sign. The shapeshifter winks, while Wendy mimes zipping her lip and throwing away the key, a special sign she and Dipper have had since "The Inconveniencing." Earlier in the episode, when Dipper and Wendy run into Soos and Mabel, Dipper initially worries that they might be the shapeshifter. Their goofy antics convince him they aren't.
  • Something That Begins with "Boring": Mabel tries to start a game of "I Spy" in a dark and empty bottomless pit.
  • Sour Outside, Sad Inside: Beneath his Jerk Ass persona, Robbie is actually very insecure and lonely. After he's hit rock-bottom, Mabel picks up on this and makes it a personal goal to try and cheer him up, which succeeds, leading him to Take A Level In Kindness.
  • Spaghetti Kiss: Apparently Old Man McGucket had one with a raccoon over a piece of meat they were fighting over.
  • Spit Take: Sheriff Blubs and Deputy Durland spitting hot coffee into each other's faces.
    Blubs: I'm so confident you're going to say no that I'm going to take a long, slow sip from my cup of coffee.
    • Stan does one and lampshades it in "Boyz Crazy."
      • And in "Fight Fighters" after Mabel sneaks up behind while he relaxes in his armchair.
  • Spoiler Opening: Paying attention to the part with the photos in the opening shows Gideon, the gnomes, Blendin Blandin, and the Summerween Trickster. Following this is a split-second image of Bill Cipher.
  • Spoof Aesop:
    • In "Summerween", Stan learns to focus on what is truly important in life: pure evil!
    • In "Love God", Stan learns that being loved is overrated and being feared is priceless.
  • Stable Time Loop: Happens in both of the Time Travel Episodes.
    • "Time Travelers Pig": Blendin Blandin is sent from the future to Set Right What Once Went Wrong by cleaning up temporal mess that was apparently started by the twins. He ends up running into them by accident, and after a series of events, the twins end up stealing his time machine. Their misuse of said time machine is what causes the mess that Blendin was supposed to clean up.
    • "Blendin's Game": At the beginning of the episode, Soos teaches the twins a trick on how to get free snacks out of a snack machine. After going back in time, Mabel ends up teaching the same trick to a 12-year-old Soos.
    • Also in play in both episodes regarding Stan's red screwdriver. Blendin stole it during "Time Traveler's Pig" in order to fix his time machine, and had kept it until "Blendin's Game," where he accidentally drops it in Soos' yard, which prompts him to go to the Mystery Shack and get hired by Stan in the first place.
  • Stage Whisper: Because he Can Not Spit It Out that he has a secret crush on Wendy, Dipper just tends to mutter about it to himself instead, while still at a distance that she could likely hear. Subverted, as Wendy eventually tells him she knew all along, partly because of how obvious he was about it.
  • Stalker with a Crush: Lil' Gideon, BIG TIME.
  • Stalking Is Funny If It Is Female After Male: Subverted with Giffany. There are points in the episode where her relentlessly stalking Soos is played for comedy, but it's not because she's a girl and he's a guy; it's because she's a computer program and he's a human. The stalking is otherwise depicted as very serious and disturbing.
  • Status Quo Is God:
    • In "Boss Mabel", Mabel makes a deal with Stan to be the Mystery Shack boss for 3 days and if she makes more money in that time, she becomes the boss for the summer. When Stan returns with no money, she declines after realizing how hard it is to be the boss.
    • In "Carpet Diem", Dipper and Mabel fight for the newly discovered room to get away from each other. Dipper convinces Stan to let him have the room, but both Mabel and Dipper miss rooming together, so they give the new room to Soos to replace his horrible break room.
      • Subverted by the fact that later shorts show that Soos does in fact keep the new room. It doesn't go away and get completely forgotten after its discovery.
    • Double subverted in the last two episodes of season 1, in "Dreamscaperers"Gideon successfully get the the deed to the Shack and the Pines are forced to live at Soos's grandma's. However in the next episodes, Dipper defeats Gideon and everybody can go back to the shack.
    • Averting the trope is a general theme of the series: Dipper getting his new hat in "Tourist Trapped" was meant to be a subtle indication that when things change, they actually change.
  • Stealth Insult: In Episode 4 of the first season, Dipper gets away with an epic one when he says this to Mabel about Gideon:
    Dipper: "I don't trust anyone whose hair is bigger than their head."
  • Stealth Pun: "Will you join us in holy matrignomey...matri-matriMONY, BLAH, can't talk today..."
    • The wax figures are cursed to come to life whenever the moon is waxing.
    • Dipper spends a good amount of time at Mabel's sock puppet Rock Opera as essentially a ghost. In other words, he's a literal Phantom of the Opera.
    • Sev'ral Timez's producer...actually produces them as clones.
  • Stock Ness Monster: The Gobblewonker.
  • Stock Punishment: Grunkle Stan gets subjected to it in "Irrational Treasure."
  • Stylistic Suck: The "Fixin' it with Soos" shorts. Soos claims to have edited them himself, and they're rife with badly animated clip art and lousy green screen effects. The "Gravity Falls Public Access TV" shorts also get it on it, showing a Mystery Shack TV ad with lousy editing and green screen footage.
    • Several of his computer graphics shots have a watermark of the free trial software he uses to make his segments.
  • Subliminal Seduction: Due to Robbie's song containing hidden backwards messages.
    • Possibly subverted, as it's not clear if it actually worked. Wendy says afterwards that she doesn't care about the messages and she mainly seems to be upset that his supposedly romantic gesture was just a sleazy attempt at manipulating her.
  • Suck E. Cheese's: Hoo-Has pizza place, complete with an animatronic rock and roll badger. Stan calls the place a nightmare, but is instantly seduced by the amount of money it can pull in.
  • Sudden Downer Ending: Dreamscaperers.
  • Sunglasses at Night: Sheriff Blubs wears sunglasses while on a nighttime raid in "Headhunters".
  • Survival Mantra: Mrs. Gleeful has one. "Just keep vacuumin', just keep vacuumin'..."
  • Suspiciously Specific Denial:
    • From "Fight Fighters":
    Grunkle Stan: There's a great uncles day?
    Mabel: Of course it's not a day I made up!
    • From "The Deep End":
    Mabel: There's certainly not a mermaid in there if that's what you're implying. Who said anything about a mermaid?
    • From "The Land Before Swine":
    Grunkle Stan: I'm not acting suspicious! You're acting suspicious! What's a pig?!
  • Take That:
    • Grenda and Candy wanting to read "Wolfman Bare Chest" on their sleepover, and Dipper (in Mabel's body), is disgusted.
    • The entirety of "Boyz Crazy" is a Take That towards 90's boy bands.
      • More specifically, it was a Take That against the highly manufactured nature of 90's boy bands, and less against the actual singers themselves.
    • One of the chants in "Dreamscaperers" is "Inceptus Nolanus Overratus," which roughly translates to "Inception [by] Nolan [is] Overrated."
    • In "Soos and the New Girl", there's a store in the mall clearly modeled after Hot Topic called "Edgy on Purpose".
    • The "Clay Day" short from "Little Gift Shop of Horrors" makes a jab at CGI animation for killing off Stop Motion animation, but also at people who claim that CGI is inferior to Stop Motion because it "has no heart".
    • Similar to "Boyz Crazy", the entirety of "The Love God" is a big joke against the hipster community, something which Oregon is infamous for.
    • At the start of "Northwest Mansion Noir/Mystery", Dipper is watching a show called Ghost Harassers on the Used To Be About History Channel. Other programs include Crawdads in Tiaras and Florida: The Show.
  • Taking Advantage of Generosity: Wendy very much takes advantage of Mabel's Benevolent Boss attitude in "Boss Mabel."
  • Tag Along Kid: Inverted by Soos, who often fills this role. He's an adult but enough of a man child to be more like a knuckleheaded tag along big brother.
  • Taxidermy Terror: The Lumberjack's Ghost in Northwest Mansion Mystery animates all the taxidermy in the house, making them bleed from the mouth, chant about "ancient sins", and attack the guests at the party.
  • The Only One I Trust: While Dipper has yet to truly be betrayed by anybody, the journal he finds warns him not to trust anyone in Gravity Falls. Dipper decides that there is one person he can always trust: Mabel.
    • In "Not What He Seems", she ends up betraying that trust by letting the portal beneath the Shack activate, choosing to place her faith in Stan's convictions over Dipper's caution.
  • The Talk: Stan decides to give one to Dipper in the episode "Carpet Diem". Unfortunately, it's Mabel in Dipper's body. Blink and you'll miss it, but the title of the book Stan uses is Why Am I So Sweaty: Your Body Explained in Horrifyingly Uncomfortable Detail.
    Mabel: Goodbye childhood...
  • There Was a Door: When Mabel drives away with Mermando in "The Deep End", she breaks an entirely new hole in the chain-link fence instead of going back out through the one right in front of her. This could be attributed to Rule of Cool or Rule of Funny, though.
  • Team Pet: Waddles the pig.
  • Team Rocket Wins: See The Bad Guy Wins above.
  • Tears of Joy: The Summerween Trickster cries tears of candy corn when Soos eats him.
  • The Teaser: Each episode begins with a cold open.
  • Technologically Blind Elders: Dipper and Stan think that Robbie is brainwashing Wendy with his music, so they take his CD and try to listen to it slowed down. Stan mistakes it for a vinyl record, and puts it into a record player. It doesn't work, and Stan is confused.
    • In the episode "Little Dipper", Gideon kidnaps Dipper and Mabel, and he calls Stan for ransom. Stan doesn't believe him.
      Gideon: "You don't believe me? I will text you a photo!
      Stan: "'Text me a photo'? Now you're not even speaking English. (hangs up)"
  • Teens Are Monsters: According to the late owners of the convenience store.
  • Tell Him I'm Not Speaking to Him: Mabel gives Stan the silent treatment in "The Land Before Swine".
  • Tempting Fate: In "The Time Traveler's Pig", Soos comments that the only thing that could possibly cause the rigged dunk tank to dunk Stan is a "futuristic laser arm-cannon."
    • Also, in "Headhunters", Mabel says she is "99% sure" she got rid of all the wax statues.
  • Testosterone Poisoning:
    • The manotaurs are testosterone waterboarding.
      Testostoroar: I have three Y chromosomes, six Adam's Apples, pecs on my abs, and fists for nipples!
    • His name is "Manly" Dan for a reason.
  • There Is Another: Gideon has the second volume of Dipper's book. And presumably there's a first... Stan has it
  • This Is My Chair: Stan and Gideon battle over a poolside chair in "The Deep End".
  • Those Two Guys: Lee and Nate in all their major appearances.
    • Sheriff Blubs and Deputy Durland, as well.
  • Tickle Torture: In the episode "Little Dipper", Mabel and Dipper defeat L'il Gideon by tickling him until he loses control, at which point Stan rolls him out of the shop.
  • Time Travel Episode: "The Time Traveler's Pig".
    • And its sequel, "Blendin's Game".
  • Time Travel Romance: Briefly, but upon travelling ten years into the past, Dipper ends up running into a five-year-old Wendy. She thinks he's cute, which gives him a taste of his own medicine.
  • Tomboy and Girly Girl: Wendy and Mabel respectively.
  • Tome of Eldritch Lore: Robbie uses a cursed CD case to hypnotize Wendy in "Boyz Crazy". You might even say it was a Necromisong.
  • Tongue Trauma: Dipper came close to this in "The Hand That Rocks The Mabel".
    • And then in "Carpet Diem", an owl apparently tried to eat Dipper's tongue while he was sleeping outside.
  • Took a Level in Badass: Dipper and Mabel in "Headhunters"; Dipper deserves an honorary mention in "Dipper Vs. Manliness".
    • Stan in "The Land Before Swine", when he attacks and rides a pterodactyl.
    • Wendy in "Into The Bunker", no doubt.
    • Soos in "Soos and the Real Girl".
  • Too Kinky to Torture: Bill Cipher is a non-corporial being, so he can't experience physical sensations. That is, until he tricks Dipper into letting him possess his body. He describes pain as "hilarious" and goes out of his way to abuse his new body as much as possible.
  • Too Much Information: In the "Trooth Ache" section of "Bottomless Pit", Stan ends up wearing a set of false teeth that make him incapable of lying, and, apparently, discretion.
  • Torso with a View: Happens to Dipper in "Dreamscaperers," though justified because he, Mabel, and Soos were inside Grunkle Stan's head trying to stop a mind-invading demon from stealing the combination to Stan's safe.
    • Also happens to Dipper 2 in "Double Dipper" after he drinks some soda. Again justified, because it's fairly obvious that the clones don't have normal human anatomy internally, since they die when they're touched by water, and since Paper Jam Dipper was somehow able to live while looking like a slinky.
  • Totally Radical: The members of Sev'ral Timez talk this way, as well as the boys from "Dream Boy High".
  • Tough Love: This is Grunkle Stan's mindset with how he treats Dipper.
  • Town with a Dark Secret: Almost said word for word by Dipper in "Tourist Trapped".
  • Trademark Favorite Food: The recurring extra in the "Free Pizza" shirt really likes... pizza.
  • Training Montage: Both Dipper and Grunkle Stan go through one in "Dipper vs. Manliness".
  • Troubling Unchildlike Behavior: Gideon's hobbies include attempted murder and demon summoning.
  • Truncated Theme Tune: Starting with Northwest Mansion Noir/Mystery, a shorter cut of the intro is used.
  • Truth in Television: From the landscape to the flora and fauna, rural Oregon is extremely well-represented in the show. Even the layout and occupants of the town, while exaggerated a bit, would fit right into that environment.
    • In "Little Dipper", Dipper feels insecure because Mabel is revealed to be growing faster than he is, despite them being the same age. This makes sense: as anybody with a similarly-aged sibling of the opposite sex can attest, there is an awkward phase growing up caused by the fact that girls hit puberty earlier than boys.
    • In "Northwest Mansion Mystery", the lumberjack ghost explains that he died because the loss of too many trees ended up causing a landslide. In Real Life, tree roots play a very important role in soil stability, and deforestation poses a high risk for landslides.
  • Twenty Minutes into the Past: The show is set in the summer of 2012, exactly when the series debuted. Later seasons become this trope though it seems to be intentional, given the supposed 2012 apocalypse.
  • Two Girls to a Team: The Mystery Shack is made up of three guys and two girls.
    • Not counting the twins, Wendy's gang of friends is made up of four guys and two girls, at least until Robbie broke up with her. Justified since Wendy is One of the Boys.
  • invokedUnfortunate Implications:
    Soos' Grandmother: I would like to see you settled before I ascend to heaven to live with the angels.
    Soos: And with Grandpa!
    Soos' Grandmother: ...No...he is not there.
  • Ultimate Evil: Bill Cipher, the most powerful monster ever encountered by the writer of the books.
  • Unexplained Recovery: Agent Powers and Agent Trigger surviving the zombies that dragged them into the woods in "Scary-Oke". Subverted in "Not What He Seems", when Powers explains he used Trigger as a human shield.
    • Again in "Not What He Seems", Trigger's escape from the crashed Humvee with his ear-microphone destroyed and a tree branch restraining him was off-screen.
  • The Un-Hug: Awkward sibling hug.note 
  • Unlimited Wardrobe: Mabel wears a different sweater in every episode, sometimes even multiple sweaters in the same episode.
  • Un-Person: Quentin Trembly.
  • The Unreveal: Soos finds a memory in which Stan enters the secret passage behind the snack machine, but closes the door before he can reveal what’s behind it, proclaiming it "boring."
    • In one of the "Dipper's Guide to the Unexplained" shorts, Dipper and Soos find an all-knowing mailbox entity. After testing it with a few questions, they are just about to ask "Who wrote the journals?" Sadly, Mabel comes in and puts in a video of her shoving gummy worms up her nose, and the mailbox, offended, vanishes explosively.
  • Unscientific Science: In "Carpet Diem", Dipper explains how Experiment 78 switches minds:
    Dippper: (reads the label) "Electron Carpet. Atoms can switch electrons. The carpet must create a charge so strong that it can switch MINDS!
  • Vacuum Mouth: The skull from the Tumbleweed Terror pinball game.
  • Vague Age: Gideon Gleeful. His white hair suggests he's Older Than He Looks, but he's extremely short and has a baby face. His age has yet to be revealed in the show, but supplementary material has confirmed that he's nine.
    • Soos was this until the episode "Blendin's Game", where it's finally confirmed that he's 22.
  • Vagueness Is Coming: Bill Cipher gives on of these to Soos and the twins near the end of "Dreamscaperers", telling them that "a day will come in the future where everything [they] care about will change".
    • They get the same treatment three episodes later, this time by Experiment 210.
  • Vampires Are Sex Gods: The G-Rated version. Brought up by Mabel several times.
  • Vanity License Plate: If you look closely, the plate on Grunkle Stan's car says "STNLY MBL".
    • Which is strange when you realize that Stan's name is Stanford, not Stanley.
  • Verbal Backspace: This happens multiple times in The Legend of the Gobblewonker when Dipper needs to reasses the number of back-up cameras he has when they get smashed.
  • Vignette Episode:
    • "Bottomless Pit"; the gang tells stories to pass the time while they're trapped in the titular pit.
    • "Little Shop of Horrors"; Stan tries to convince a stranger who arrives at the Mystery Shack after hours to buy stuff by telling tales about them.
  • Villain with Good Publicity: Everyone considers Gideon to be a cute lovable child. That is, until the Season 1 finale when Stan exposes the truth about Gideon, and ends Gideon up in prison.
    • Turns out the Northwest family is this as well.
  • Villainous Crush: Gideon has one toward Mabel.
  • Visual Pun: The Mystery Shack's sign has the second S in an odd position or completely taken off, spelling out MYSTERY HACK. Considering who owns the place...
    • Additionally, Candy dressing like a piece of candy in "Summerween".
  • Vocal Evolution: It took Alex Hirsch a few episodes to settle into his Grunkle Stan and Soos voices. They sound a little off and unusually high-pitched in the beginning.
  • Voices Are Mental: In "Carpet Diem", the voices switch along with the characters as they move from body to body.
    • Bipper has Bill Cipher's voice coming out of Dipper's mouth.
  • Voluntary Shapeshifting: Experiment 210, an Eldritch Abomination that the gang encounters while seeking out the Author.
  • Vomit Discretion Shot: While the gnome vomits on screen, it throws up rainbows. Taken to extremes when it fills up the entire closing credits of the first episode.
    • Later, in "Boss Mabel", we see a group of tourists from Stan's point of view. They all appear as walking, talking wallets, and one of them vomits coins.
    • In "Carpet Diem", Mabel, in Dipper's body, pukes into a toilet.
  • Weirdness Censor: This is probably one of many reasons that the residents of Gravity Falls still live there; they never believe when they actually see something supernatural, and when they do, they ignore it like it was nothing.
    • "Society of the Blind Eye" revels that the titular Society has been acting as one, erasing the memories of people who have seen anything supernatual.
    • Even after the events above, the citizens still try to rationalize the weirdness. For instance, the gravity anomaly is passed off as a mini Earth burp.
  • Weirdness Magnet: It's true that Dipper often goes off looking for the supernatural, but more often than not, the supernatural finds him first.
  • We Will Meet Again: Used three times so far: the leader of the gnomes, Gideon and Blendin Blandin all swear revenge after being defeated.
  • Wham Episode:
    • "Dreamscaperers" has Gideon, after the Pines foil two attempts at getting the deed for the Mystery Shack from Stan's safe, instead blows up the safe with dynamite and immediately brings in a demolition vehicle to start tearing down the Shack while the Pines and Soos look on in horror.
    • In "Gideon Rises," Stan reveals to the townspeople that Gideon was illegally spying on them. Gideon is sent to jail, leaving behind the second journal. Dipper and Mabel decide to tell Stan about the journals... unwittingly giving him all three journals. Because not only did Stan take Gideon's book, he's had the first one all along. The episode ends with Stan ready to open... something.
    • "Society of the Blind Eye" not only completely overturns a popular and supposedly supported fan theory, but ends with some dark (and bloody) potential foreshadowing.
    • "Northwest Mansion Noir/Mystery": The Northwest family as it turns out has been one long chain of cheats, Pacifica has been a victim of abuse and ends her rivalry with the Pines twins, and according to McGucket, the apocalypse is coming in less than a day.
    • "Not What He Seems": Stan's been stealing radioactive waste to power his world ending machine and gets arrested by the FBI. The twins discover that the real Stan Pines died in a car crash and that their grunkle is not what he seems, all leading up to a confrontation as gravity fluctuates when the portal rips open, revealing the author of the journals, Stan's brother.
  • Wham Line:
    • "After all these years... Finally, I have them all. Here we go."
    • "The author of the journals... my brother."
  • Wham Shot:
    • At the end of "Northwest Mansion Noir/Mystery", McGucket has fixed the laptop. There's a timer on it counting down to the apocalypse. It's less than 24 hours away. And then the camera pans to a banner the Northwests have in their house of a familiar triangle with an eye, over an image of what looks like people burning alive.
    • In Not What He Seems, Stan's portal finally opens and a man steps out, who he identifies as the author of the journals, his brother.
    • And before that, a newspaper clipping that reads Stan Pines Dead, though what this means for the characters is still unknown...
  • What Did I Do Last Night?: Mabel after waking up from her sleepover with Candy and Grenda.
  • What Happened to the Mouse?: So far, the two Dipper clones that rode away on Robbie's bike in "Double Dipper" have yet to return.
    • As has the wax head of Larry King from "Headhunters".
    • A minor example: in the fourth episode, Mabel saves a lobster that was going to be eaten at a restaurant then bring it to the shack's tank. In later episodes, the tank is empty.
  • What Have I Become?: In "Boss Mabel", Mabel reaches her breaking point with Soos and Wendy. She tells them off for their goofing off in a Stan-like manner, ending up with the fez on her head. She quotes this verbatim when she looks in the mirror.
  • When Life Gives You Lemons: Each member of the Pines family has a character-establishing quote based on this:
    Dipper: "When life gives you lemons, extract the juice and use it to draw a treasure map in invisible ink. That really works! Seriously!"
    Mabel: "When life gives you lemons, draw faces on those lemons and wrap them in a blanket. Ta-daaa! Now you have Lemon Babies."
    Grunkle Stan: "When life gives you lemons, call them 'yellow oranges' and sell them for double the price."
  • What Measure Is a Non-Human?: Played for laughs in "Summerween". Soos hits the Trickster and shatters him completely when he was about to kill the kids, and freaks out when he thought he accidentally hit a guy. After Soos eats the Trickster, the episode draws to a close with an Everybody Evil Laughs Ending as soon as it ends, Soos nonchalantly says "I ate a man alive tonight."
    • It should be noted that The Trickster was very happy that Soos liked eating him.
  • When You Coming Home, Dad?: Soos is really hung up about his deadbeat dad.
  • Where the Hell Is Springfield?: In Tourist Trapped, the map of Oregon shows Gravity Falls to be dead-center in Oregon, somewhere between Crook and Deshutes county. But in Skaryoke, a doppler map places it closer to Baker city, almost on the border with Idaho.
  • Which Me?: In "Double Dipper" a few times.
    Tyrone: Hey buddy, it's me, you.
  • Whole Episode Flashback: "Bottomless Pit!" is focused on the characters telling stories, at least one of which we discover actually happened. Also qualifies as a Vignette Episode, as listed above.
  • Who Names Their Kid "Dude"?: It's revealed in "Double Dipper" that Dipper is Only Known by Their Nickname, causing Wendy to remark "I thought your parents just hated you or something".
  • Widget Series: Definitely the most off-kilter series on the channel.
  • Wild Goose Chase: In "Not What He Seems", Stan pays a taxi driver to drive in the opposite direction he's running in order to misdirect the government agents trying to arrest him.
  • The Wild West: The theme of the Tumbleweed Terror pinball game.
  • Wild Wilderness
  • Wimp Fight: In "The Hand that Rocks the Mabel", Dipper and Gideon manage to get into one while falling off a cliff, a stark contrast to the one that they have during the season finale.
    • In "Double Dipper", this ends up happening between Dipper and all his clones. Dipper even lampshades this beforehand, saying "We're all exactly the same mentally and physically. If we start fighting, it'll just go on for infinity!"
  • A Wizard Did It: A number of plot holes are filled by the reminder that Quentin Trembley passed a lot of weird laws in his time in Gravity Falls office. It's why holding the physical deed to a building - holding it in your hand - means you own the building, and why the police are allowed to send a nine-year-old to adult prison.
  • Woobie, Destroyer of Worlds:
    • Giffany counts for some, given that she has abandonment issues and that no one in her debut episode treats her like a person: Soos breaks up with her because she can't attend his cousin's engagement party, Mabel and Dipper encourage Soos to date real girls and return Romance Academy to the store, and three other people have apparently returned her without even a Mercy Kill. That said, she is more "destroyer" than "woobie" in that she takes over Hoo Ha's Jamboree to stalk Soos, force him to upload his brain into the game, and break him by talking.
    • The lumberjack ghost in "Northwest Mansion Noir" has no qualms about hurting children in his quest for revenge on the Northwests, but he and the other lumberjacks who died were cheated out of a party supposedly held in their honor, and he suffered a Cruel and Unusual Death. Dipper even expresses some Sympathy for the Devil while exorcising the ghost to keep Mabel safe.
  • The World Is Not Ready: Based on the events of "Boss Mabel", it seems that the tourists aren't quite up to seeing real magical creatures just yet.
  • Worst News Judgement Ever: "Cheese Crust Pizza Declared 'Delicious'." In other news, "War or Something..."
  • Would Hurt a Child:
    • The cursed wax figures in Episode 3. They try to murder Dipper and Mabel without hesitation.
    • Also, in "Summerween", the Summerween Trickster. In fact, he makes it look like he KILLED a child until the end of the episode!
    • Rumble, the Fight Fighter, was genuinely trying to kill Robbie, endangered Stan and Mabel by toppling the water tower, and beat up Dipper with a nearly lethal combo attack just because Dipper had lied to him.
    • Every antagonistic creature/person in the series ever qualifies as this.
  • World of Badass: Every major character is some form of badass, be it often or only when the situation calls for it.
  • Wouldn't Hurt a Child: The convenience store ghosts in Episode 5. They would hurt teenagers though.
    • Robbie in "Fight Fighters". Even after Dipper nearly gets him killed, he's unwilling to go through with beating him up.
  • Wrong Genre Savvy: Mabel in "Sock Opera" towards the end:
    Mabel: Don't worry, I have seen enough movies to know this is the part where the audience thinks this was all part of the show and loves it. Cue applause!
    (audience boos and leaves)
  • X Meets Y:
  • Xtreme Kool Letterz: Sev'ral Timez.
  • Yandere: Gideon.
    • Newly, and on a higher level, Giffany.
    Giffany: Oh, I am crazy! Crazy for you, Soos!"
  • Yellow Eyes of Sneakiness: Bill Cipher has a slitted pupil, and his sclera turn yellow when he possesses a body.
  • You Are Number Six: How Dipper names his clones, with the exception of Tyrone (who refuses to be called "Number Two") and Paper Jam Dipper.
  • You Can't Fight Fate: In "The Time Traveler's Pig," no matter what he tried, Dipper would always inevitably hit Wendy in the face with a baseball. The one time he finally figured out how to avert this he needed Mabel to help so she wasn't there to win Waddles and Pacifica got him instead. For Mabel's sake Dipper had to go back and hit Wendy again.
  • You! Exclamation:
    • In "Double Dipper", after melting his photocopied clones to mush, Dipper believes they're all gone. Until he hears Tyrone exclaim "YOU!" from behind.
    • In "Boss Mabel", Mabel gives one of these to Grunkle Stan when she gets tired of the shabby treatment he gives his employees and his customers.
    • In "The Land Before Swine", Grunkle Stan gives one to Mabel's pet pig Waddles after the latter eats the former's corn-cob sculpture of a unicorn, driving away Stan's customers.
    • Bill Cipher tosses out a few in "Dreamscaperers."
    • Rumble McSkirmish gives Dipper a really over-dramatic one in "Fight Fighters".
  • You Gotta Have Blue Hair: Kraz.
  • You Killed My Father: Dr. Karate killed Rumble McSkirmish's father (again), making it his motivation for fighting. Rumble also assumes that this is the reason Dipper wants him to fight Robbie.
  • You Fail Paleontology Forever: "Land Before Swine". Not only is the "pterodactyl" completely ugly (see Ptero Soarer) for details, but all the dinosaurs are hard to look at. Plus Oregon is actually one of the few states that has had no dinosaurs discovered in it.
    • Note, however, that just because no fossils have been found yet doesn't necessarily mean dinosaurs didn't live there. The rest of the episode's problems still qualify though.
  • You Mean Xmas: Apparently, the citizens of Gravity Falls love Halloween so much they celebrate it twice and call the second time "Summerween". It's exactly the same except they carve watermelons instead of pumpkins.
  • Your Worst Nightmare: You get to see it if you look into a Gremloblin's eyes.
    • In "Dreamscaperers," Bill unleashes Mabel and Soos's personal nightmares on them after they stop him from getting the safe code.
  • Your Mom:
    Nate: Good job throwing the kid off the fence, genius!
    Lee: Your mom's a genius.
  • Youth Is Wasted on the Dumb: In "The Inconveniencing", the twins tag along with Wendy and a bunch of her friends while they break into an abandoned convenience store, and they aren't able to do a darn thing once it turns out to be haunted.
  • Zombie Apocalypse: Nearly happens in "Scaryoke", when Dipper accidentally raises an army of the undead while trying to prove the validity of the journal to the government agents.
  • Zombie Gait: Referenced when Wendy and Dipper watch a cheap zombie movie:
    Dipper: They're slow! Just power walk away from them!
