Nightmare Fuel: Gravity Falls

Should I be one, or the other? How about both?

"Heheh, good luck sleeping tonight!"
Soos, "Into the Bunker"

A common assumption is that Disney's Gravity Falls is strictly a kid's series. After your first viewing, you'll start to doubt that.

  • The creepy whispering in the intro, along with those unsettling chords and flickering subliminal imagery, and the dying/fading on the last note, from the intro will never cease to send a chill down your spine.
    • It's "Three Letters Back" in reverse — the cipher for the initial end-of-episode codes. It eventually switches to other messages when the cipher changes accordingly.
  • Bill Cipher. Introduced near the end of the first season, he's described as the most powerful and dangerous being in Gravity Falls, and while a very strong target of Love to Hate among the fandom, everything about him is unsettling at best and horrifying at worst. To elaborate:
    • He's a demon. No kid-friendly minced terms here, he's explicitly identified as a demon.
    • He's completely insane and impossible to predict. Besides talking, his very first on-screen action was randomly ripping the teeth out of a nearby deer, showing them to the person who summoned him just to give them a scare, and then putting the teeth back in and acting as if nothing happened.
    • However, despite this, he seems to have near-omnipotent intelligence. The casual way he talks to the characters makes it seem like he's constantly one step ahead of them; like he can predict every individual thought and motive that goes through their heads and always knows the exact words to say in order to play them like a fiddle. He may have very limited power over the physical realm, but every time you're near him, you get this underlying feeling of helplessness.
    • He has the power to enter your mind and read as many of your memories as he pleases. It's implied there's a way to defend yourself from him, but we have yet to learn it.
    • If he's able to persuade you (which, again, is very easy for him), he can take over your body. And he has no regard for your body's physical well being when he does so; quite the contrary, he goes out of his way to abuse it as much as possible.
    • He's always watching you. Always.

    Season 1 
  • Episode 1, "Tourist Trapped". A bunch of gnomes wanted to kidnap and marry Mabel, a little girl, which is unsettling as it is. That's not even considering the fact they can be old even by human standards.
    • They were rather feral when Dipper comes to rescue Mabel, one of them attempting to eat Dipper's face off.
      • And then there's the big gnome monster that they all form together...
  • Episode 2, "Legend of the Gobblewonker". McGucket has made these robots before, and has used them on populated areas just to get attention. As is hinted later, this is probably him being nice.
  • Episode 3, "Headhunters". Wax Sherlock Holmes tried to outright murder Stan with an axe.
  • Episode 4, "The Hand That Rocks The Mabel", when Lil Gideon shows his true colours. He's unstable, violent and seems to believe that Mabel is secretly in love with him. Heck, he tried to cut out Dipper's tongue and kill him just to get to Mabel. And keep in mind Gideon is three years younger than Dipper!
    • It doesn't help for the fact that Gideon has the voice of Flapjack and while he sounds a tad goofy, it also proves to be quite unsettling.
    • One has to wonder if he was born this deranged or if his contact with the forces in the Journal caused him to be this way.
  • Episode 5, "The Inconveniencing", has so many...
    • POSSESSED MABEL. It's creepy enough in concept, but actually seeing it...
    • The cooler monster. (Whatever happened to it, anyway?)
      • It was presumably just an illusion.
      • Alex Hirsch's response when asked about the monster if it'll ever be explained? "No."
    • When Dipper turns around and sees that his and the others' reflections have become skeletons.
    • The fates of the teenagers that the twins venture to the store with: Being trapped inside a television screen, a video game, a cereal box cover, and a hot dog that's being cooked.
    • And judging by the sound effect and reactions of the characters watching, the cereal box one was a Gory Discretion Shot.
      Cereal Box Bird: I'm bonkers for eating you alive!
    • More "Getting Crap Past the Radar" than nightmare fuel. But it's really really surprising the show was allowed (being Disney) to get away with using the word "Murder" and showing two corpse outlines. Darker and Edgier Disney indeed.
  • Episode 6, "Dipper vs. Manliness" we're introduced to the leader of the manotaurs! Only for him to be DEVOURED on screen by the real leader SECONDS later. While on its own the scene is bad enough, you must think of how Dipper must feel knowing these creatures REGULARLY eat their own as offerings. It's implied that this isn't the first time this has happened. Doubles as a Moment Of Awesome when he finally stands up to them however.
    • When the Leader pulls a spear out of his chest with screaming and blood and everything. Uhhh...
  • Episode 7, "Double Dipper", has two that particularity spring to mind. Firstly, the the copy of Dipper's (dismembered) arm bubbling and melting away, and secondly, Paper-Jam Dipper.
    • How about Dipper's dismembered copy arm in the first place? Think about it? A disembodied arm crawling towards you, not to mention the music that was playing in the background of that scene.
    • Paper-Jam Dipper welcomed his death. Apparently he was suffering from his deformities.
  • Episode 8, "Irrational Treasure". Not only do Blubbs and Durland suddenly become frighteningly competent (And yet somehow remain just as dense), the episode gives us the fear that the people we trust to protect us can turn on us the moment we least expect them to.
  • Episode 9, "The Time Traveler's Pig", has the Time Baby, a large headed, red eyed baby that seemingly controls all of time.
  • Episode 10, "Fight Fighters", lands Dipper in a shockingly realistic "fight with a bully" scenario, especially by Disney Channel standards.
  • Episode 11, "Little Dipper", has Gideon return to thwart the Pines family and the Shack. He really loses his grip the whole episode and shows very Yandere tendencies.
    • We also see his mom, who seems to be very neurotic and dead-set on just vacuuming all the time. Did Gideon drive her up the wall...?
      • He strikes some real Nightmare Faces, too.
      • The way Gideon screams at his parents, demands his father look him in the eye and grabs him by the face, etc., are all strongly reminiscent of a habitually abusive parent lashing out at a child rather than simply an outrageously bratty kid acting out.
    • Then there's when he decides to shrink Stan...
    Gideon: Heh heh heh...Hahahahah! WHAT AM I DOIN'!? I don't need ransom! I have this! I'll just shrink Stan and take the Shack by force! And if the rest of you get in my way... (Rips heads off Pines family figurines) SMASH!
    • And he's only 9! What will he be capable of when he's an adult?
  • Episode 12, "Summer-Ween", has a monster who tasks Dipper and Mabel with bringing him candy, or he'll eat them. He's scary enough at the start, but his transformed state is even scarier.
    • And to demonstrate he's not kidding, the Summerween Trickster grabbed a random kid and ATE HIM WHOLE! And this is the first five minutes of the episode!
    • The Summerween Trickster's actual face behind the mask.
    • How much the Trickster looks like Noh-Face without his costume.
    • Stan's attempts to scare the two Trick-or-Treaters are kind of scary, even if the kids don't think so. His first attempt is to wear a mask that makes it look like his face is melting off his skull.
  • Episode 13, "Boss Mabel." That poor, poor couple Dipper caused to go insane by looking into the Gremloblin's eyes. They're last seen carried away on stretchers in catatonic states, with their eyes wide in frozen terror. Yes, Disney openly admitted to Mind Rape on this show.
  • Episode 15, "The Deep End", features a lifeguard who is so dedicated to his job that it's almost creepy.
    • The dead, mummified looking merman seen in episode 1 becomes extremely unsettling now that the twins have learned merfolk are real, intelligent beings.
      • Most likely it's intended to be a reference to the Fiji Mermaids, a common carnival attraction about a century ago. Mind you, they were nightmare fuel in their own right, and usually consisted of a mummified ape sown together with a fish. Of course, the one shown in this episode IS human sized...
    • The kid in the pool filter when you think about it for too long.
  • Episode 16, "Carpet Diem." Soos is switched with Waddles, and while he's being hunted by Old Man McGucket, Waddles is off screen. Whatever he was doing, it resulted in a marriage proposal with a woman being so unbalanced that a mute, bumbling man with no indication of sapience can go from total stranger to marriage material in the space of a few hours — and when he does start behaving like a human being, she's no longer interested.
  • Episode 17, "Boyz Crazy." The sole fact that the producer of Sev'ral Timez has genetically engineered the band and KEEPS THEM LOCKED IN AN OVERSIZED HAMSTER CAGE is kind of frightening.
    • The clones kept in test tubes. There was an adult, an older kid, a younger kid, a baby... and a fetus.
    • Robbie brainwashing Wendy with his song. The backmasked message itself it pretty damn creepy, too:
      Low Voice: You are now under my control. Your mind is mine.
    • Plenty of scare chords related to that above message.
    • The manager of Sev'ral Timez. What a bastard. It's clear he's abusive to the people he creates.
    • The shit-eating grin Robbie has on his face before he brainwashes Wendy with his song. He knows damn well that what he's doing is despicable and disgusting.
    • Sev'ral Timez is released as babes in the woods. Candy says casually, "They won't last a week."
  • Episode 18, "The Land Before Swine". When the Mystery Shack gang first comes across the pterodactyl's nest, several skeletons are seen nearby.
    • As the gang runs from the pterosaur, they pass a T. rex stuck in amber that wriggles its arms, suggesting that it might free itself someday.
      • Not to mention earlier they see a trapped dromaeosaurid wiggling its free finger.
    • Also, Old Man McGucket getting swallowed alive by the baby pterodactyl, and implied to have eaten his way out of it at the end.
    • There's also the general fear of having a beloved pet being snatched away by a predator.
  • From Episode 19, "Dreamscapers", we have:
    • Gideon winning.
    • The fact that Gideon wants the Shack so badly that he summoned a demon to do it. Not a "spirit" or a "monster" but an actual demon. There's also the fact that the page about the demon in Dipper's book is bloodstained.
      • The way Gideon summons Bill is with backmasked words. But if you reverse it, he's actually saying "Backwards message". Still doesn't make the actual scene any less creepy, though.
      • The fact that the unknown author of the journals specifically noted not to EVER summon Bill. Out of all the horrible things that haunt GF, this being scared the author the most. Its entirely possible Bill is the "Him" the author speaks about in the first episode that is watching him.
      • Not the mention the fact that the page of the Journal 2 describing him says that he's appeared in the author's dreams every night for weeks, and the page before his entry in Journal 3 says "Can't sleep can't sleep can't sleep" leading to some interesting implications.
    • Mabel losing her's really not pretty.
    • Gideon's glowing eyes and freaky incantation while summoning Bill.
    • Bill knows lots of things... LOOOOOOOTS OF THINGS
    • Remember how Gideon was once angry enough to try to cut out Dipper's tongue with lamb shears? Bill tears out the teeth of a deer and hands them to Gideon, who shrieks in horror and drops them all.
      Bill: Deer teeth! For you, kid. Ahahahaha!
      Gideon: Ah- ahhhh! You're insane!
      Bill: Sure I am, what's your point?
    • Dipper getting a hole blown through his body.
    • Bill when he gets angry.
    • Bill leaving was incredibly creepy as well, complete with flickering and flashing imagery, and a healthy serving of scary sounds.
      • While he was leaving, his last words were "I'LL BE WATCHING YOU..."
      • Hell, just the fact that Bill wasnt actually defeated, he decided to just leave, because he thought the Pines were amusing and worth keeping an eye on.
    • The Stinger is the icing on the creepy cake. It's a view of a forest scene with "To Be Continued" written at the bottom, with an eerie remix of the theme song playing in the background.
    • Before the episode even aired, Bill was a source of unnerving content. On Disney's website for Gravity Falls, the game "Rumble's Revenge" yields twelve special cryptograms. When transcribed, they read:
    "i bet you're wondering who I aM."
    "i don't give up answers easilY.."
    "i kNow things. Fascinating things..."
    "your reality is a game to me. And I like gAmes...."
    "mischief is my Middle name, but not my first....."
    "thEre are six hints I will give you......"
    "1. there is a secret socIety in Gravity Falls......."
    "2. the Handyman knowS more than he thinks........"
    "3. gideon has Been searching for something........."
    "4. what goes up Is sure to come down.........."
    "5. dipper is pLaying with fire..........."
    "6. i will be returning to Gravity FalLs............"
  • Episode 20, "Gideon Rises":
    • The opening sequence.
    • Gideon screaming at Waddles to get back in the corner, coupled with his terrified expression.
    • The giant robot Gideon definitely falls under Uncanny Valley.
    • Gideon still retains his Yandere tendencies, and uses the aforementioned Gideon robot to grab Mabel and demand she be his queen.

     Dipper's Guide to the Unexplained 
  • In "Lefty", Dipper spies upon a man who never turns right and literally does everything left. Then Dipper later gets him to turn around and He's not human, but a robot controlled by tiny little creatures. The huge reveal was really creepy and completely unexpected.
    Creature 1: The time has come, brother!
    Creature 2: I can't! I have a family!
    Creature 1: You signed the oath! (both swallow poison and die)
  • The "Tooth" short. Or more specifically, the thing the tooth came from...
    "You have disturbed my slumber. Enter my mouth, children! ENTER YOUR DESTINY!"
    • If you look closely when The Head chases after the kids, you can see some SKELETONS hanging off the bottom of it. How many people died from this thing!?!
    • Bear-O is a piece of work too.
  • The Hide Behind at the end of the short.
  • Watching all of the shorts and then putting the pieces at the end of them together nets this wonderful image.
    • Not to mention when you decrypt the Red Code along the edge, it spells I WAS SO BLIND, HE LIED TO ME, THE DARKNESS IS NEAR.
  • The Hide-Behind has a rather creepy design. Fortunately, he/she/it doesn't do anything particularly harmful, and doesn't seem to want to hurt anybody.

  • If you think about it for more than about a second, Gideon's status in prison shown in the first Gravity Falls Public Access short becomes this. He's clearly got a huge amount of influence, and the people he's lording over are clearly pretty unstable, and coordinating a mass breakout is hardly beyond his means...
    • That aside, the fact that a child who might be no older than 10 would be put in a maximum security prison with people who have probably done some horrifying things to end up there seems like a big concern.
  • Octavia the 8-legged cow from "Mabel's Scrapbook". She looks harmless enough...until she zaps a passing eagle with her Laser Eyes and eats it with her Overly Long Tongue.
    Stan: Run.
  • We get more Yandere antics from our favourite Creepy Child in Creepy Letters from Li'l Gideon. He sounds rather unhinged when he mentions counting the bricks in his cell, and says he hopes he'll see Mabel "real soon".
    • There's a sequel out now;
      Gideon: I'll be getting out of here before you know it. Can't wait to together with the ol' book club: you, me and Bill Cipher! Let's see how YOU like being your soul.

    Season 2 
  • Episode 1, "Scary-oke", has a zombie invasion, with poor Soos being infected and becoming a zombie.
    • Zombie Soos is made somewhat less terrifying by still being as goofy as he ever was.
    • The glove Stan puts on in the bunker has six fingers
    • The blacklight reveals that there was blood on the journal's cover.
  • Episode 2, "Into The Bunker" has the Shape Shifter, which does exactly what its name implies. It tricks Dipper into thinking he's met the author of the journals, before revealing its terrifying, somewhat eldritch true form and trying to kill Dipper and take the journal. Dipper even discusses the fact that if it got loose, it could turn into anyone and you would never know it.
    • What's even worse is that it displays a lot more of a malicious personality than a lot of other supernatural creatures. Unlike the numerous monsters that fall under True Neutral, to the Summerween Trickster and Pa and Ma who have a Freudian Excuse, to even Bill who's motives and end goal are highly questionable, the Shape Shifter is a horrifying monster who taunts Dipper about what may happen to him if he goes too deep, transforming into a horrified Dipper before he is frozen in a chamber. Soos even lampshades it with a "Good luck sleeping tonight!"
    Shape shifter: (In Mabel's form) Should I be one, (takes Dipper's form) or the other? How about both? (transforms into an BodyHorror mixture of the two)
    • The build up to the Shape Shifter reveal was surprisingly creepy, even for this show! Dipper and Wendy, separated from Soos and Mabel, run into the "author of the journals". Everything's going fine, Dipper is happy they managed to find him and everything seems to be going okay. Then Wendy realizes that the man they're talking to is the Mascot on the can of beans down in the bunker. Realizing how bad this is, Dipper tries to head out. And then the Shape Shifter takes quite a notes from another certain shape shifting alien....
    • One of the worst parts about the Shapeshifter? He makes the exact same sound effect as the Zurg-a-Tronic Megaray, the source of many kids from the 90s nightmares.
    • The overall similarities to The Thing also add a lot of Fridge Horror. Wendy's bleeding after the initial fight with the monster...
    • Whatever that monster in the shadows was. It appears to be a spider, but we never actually see it in full form. It's also mentioned to have regenerative properties... This is assuming, of course that the monster wasn't Experiment 210 and the "author's" battle with it wasn't some sort of ruse to gain Dipper and Wendy's trust, such as shapeshifting part of itself into the "author" and ripping out the monster's tongue.
    • The Shapeshifter's last words.
    You think you're so clever, don't you Dipper? But you have no idea what you're up against. You will never find the author, and if you keep digging, you'll meet a fate worse then you can imagine, and this will be the last form you'll ever take! (As the shapeshifter is frozen it takes the form of a screaming and terrified Dipper.)
  • Episode 3: "The Golf War" was essentially a really funny, light hearted episode, but it did have two moments; when the Lilliputtians tie up Pacifica because they think Mabel would like them best if she had the chance to murder her instead (prompting another group to threaten to murder her golf tutor in retaliation), and when they all decide to work together so they can cut Mabel open. Kind of a surprise.
  • Episode 4: "Sock Opera". True to his word, Bill Cipher has been watching the twins, and makes a return in this episode while being even creepier.
    • Bipper is, granted, pretty hilarious ("BOY THESE ARMS SURE ARE DURABLE!") but he still manages to be legitimately terrifying at the same time. Bill enjoys causing Dipper's body pain way too much and his expressions when threatening Mabel are cruel in ways Dipper's face should never get.
    • Bipper wears this... GRIN on his face, half Cheshire Cat Grin, half Slasher Smile, and it's exceptionally creepy to look at.
      • The animators made Bipper's face more frightening than Dipper's could ever be by giving Bipper, in close-up at least, actual individual teeth and gums, which rotate with the angle of the head and everything, as opposed to the usual nondescript white bar you usually see in characters' mouths. It makes him look more than a little disconcerting.
    • And somehow he gets even worse in the shot where we are introduced to him dressed as a reverend. The incredible contrast, coupled with the dark clothes, his unnatural eyes and (now truly a) Slasher Smile makes him look extremely sinister.
      • The character designers really went for the jugular with that one. Word of God is that Bipper's mannerisms and reverend costume were based on two sources, Reverend Henry Kane of the Poltergeist film series and Reverend Harry Powell from Night of the Hunter. That's right, an eldritch cult leader and a serial killer who threatens children.
    • Also, the reveal that Bill can straight up possess people if he can con them into a deal with him (which is exceptionally easy for him to do), even if they have a still living spirit in them. Dreamscaperers showed that he is able to enter minds and mess around, but this is a whole other level of evil and power. If Dipper hadn't been able to possess the sock puppet and warn Mabel about what Bill had done, he could have potentially been left in the Planescape for the rest of eternity.
      • Worse yet, while most of the time when people make deals with demons, the demons have to keep their end of the bargain, even in a roundabout way, if they want what the human promises them. Bill completely destroys the laptop and still gets away with taking Dipper's body.
      • Worse still is that Bill did keep his end of the bargain. If you notice, Bill explicitly worded their entire conversation as if they were negotiating a deal. But they weren't, Dipper just assumed so. The deal was "I want any puppet." "Just one puppet?...Fine!" And then he removed Dipper's soul so his body could become Bill's puppet. He just casually outsmarted one of the most intelligent and paranoid characters ever seen on this show, and he made it look easy. Bill is extremely intelligent, crazy, sadistic, and he seems to be working towards whatever he's doing casually. Just what the hell kind of lengths would Bill go to if he ever became serious about doing something?
    • "How can you do that... if you don't exist?"
    • Perhaps one of the more unnerving things about Bipper is that, until Dipper finds a way to tell Mabel what's going on, nobody who knows Dipper finds ANYTHING strange about the way he looks, talks, or behaves. It's almost as if Bill's Reality Warper abilities convinced them all that was normal.
      • Interesting theory, but jossed: Alex Hirsch stated that the only reason they didn't show people reacting to "Dipper's" odd behavior was due to time restrictions.
    • The possession scene itself gets up here too. It's quickly Played for Laughs as Bill gets used to a physical body, but the music that starts playing combined with Dipper's screaming combined with Bipper slowly climbing to his feet as all the lighting goes red is pretty terrifying.
    • The animators seem dead-set on upping the amount of body-horror the show has. Bill conjures an eternally screaming head for no reason other than to frighten Dipper. Then he snaps his fingers and the head unravels, stripping away hair and skin, then flesh and eyes, and finally pulling the skull out of frame. The head is of course screaming the entire time.
      • Looking closely, the head's tongue ties itself in a knot as it unravels.
    • Bill's appearance when Dipper wishes for some clue or hint for the password. The full moon rolls over and is revealed to be Bill's eye.
    • "I've been keeping an-" *Bill briefly turns massive, red, and Satanically deep-voiced* "EYE ON YOU since then..."
    • Even the episode's code, once translated, makes an incredibly creepy poem:
    • Makes you wonder what Bill's planning...
  • Episode 5: "Soos and the Real Girl": The animatronics at the Suck E. Cheese's knockoff restaurant were pretty creepy to look at even before they were taken over. It doesn't help that one of them looks disturbingly like Mabel's puppet Bear-O.
    • On a similar note, some of the things that they have built into them don't really make a whole lot of sense, like the clawed hands on the Barrel Rat Robots. Considering that they looked like they were all endoskeleton they obviously weren't meant to be seen, making one wonder why they were even put on to begin with.
      • I doubt the female animatronic that Giffany possessed actually had a device that could upload people's brains. It's probably supposed to show the kind of power Giffany has at her disposal.
      • Although it's a complete coincidence (as the episode was finished long before the game came out), the animatronics have reminded many people of the indie horror game Five Nights at Freddy's.
    • In that episode, we're treated to an old coin-operated machine in the Mystery Shack that malfunctions and spews oil from its face while screaming, which terrifies a poor unfortunate little boy to tears.
    • The episode itself centers around Soos coming across a Yandere dating sim that ends up possessing the aforementioned animatronics to get to Soos and "delete" Dipper, Mabel and Melody.
      • Speaking of that Yandere dating sim, how about the split-second Nightmare Face Giffany pulled after Soos paused her and pulled out her disc to take it back to the game store? If there was any doubt about whether she was being a temperamental Tsundere stereotype (as one may expect of a Japanese dating sim), or going full blown psychotic Yandere on him, that look probably sealed the deal. Here it is for all its horrifying glory. It even resembles a face Gasai Yuno from Mirai Nikki pulls.
      • Soos playing the game on an unplugged computer isn't scary. Soos playing the game on an unplugged Desktop computer is scary.
      • It's also implied that Giffany killed her creators.
      • Implied nothing, they show that she electrocuted anyone who tried to destroy her.
      • Giffany herself has an unsettling and shaky pixelated art style that clashes with everyone else on the show, especially when she starts showing off her Contagious A.I. powers and combined with her Accent On The Wrong Syllable voice. Worse, apart from her brief screaming fit when she realized Soos was putting her up for a while, she never loses that cheerful, polite tone.
    • Her death is nothing to sneeze at. Basically, she utters a really horrifying scream and the robot she was possessing melts. Geez.
    • Anyone that has been in an abusive relationship will tell you that Giffany's speech to Soos - that real women will only judge and insult him and that staying with her is the only way to prevent being alone - hits a little too close to home to what their abusers have said to them to get them to stay.
    • Game companies needed to produce many, many copies of a game to recoup the expenses in creating a game in the days before direct download. How many other players are dead, trapped in the game, or forever under Giffany's digital thumb? And what happened to the three people who owned the game before Soos?
      • We're told that they returned the game to the store, which implies that they freaked out before Giffany had the chance to get into the serious assault phase. So it's possible that Romance Academy 7 failed miserably as far as sales went, and Soos is the only one unlucky enough to have Giffany around long enough for her to build up to "YOU WILL NEVER LEAVE ME". Still a disturbing prospect, though.
    • This episode is frightening because unlike Rumble McSkirmish, Giffany thinks. She's not locked into a set of rules like Rumble is. She's a living, thinking entity capable of complex planning and emotional manipulation. Move past her screaming match when Soos says he's leaving her to the end of the episode; she goes right back to being her charming self, gleefully describing to Soos how no real woman would ever be with him, but how she's always predictable no matter what. You can tell by the look on Soos' face that Giffany knew exactly where to hit, and that, even for a brief second, Soos really considered giving his mind to Giffany.
    • As if to prove a point how different Giffany and Rumble are, she rather casually vaporizes him in passing when her programming moves through his game.
    • Watch the dumpsters when Stan is being attacked by the badger robot. One has Robbie's "explosion" painted on it, but the second has a much more sinister symbol.
    • The woman Soos accidentally knocked over in the mall was pretty creepy as well.
    You can't undo who you are.
  • Episode 6: "Little Gift Shop of Horrors" has an unnamed person being greeted into the Mystery Shack late at night. After Stan tells three different stories about some of the items he's selling, the person decides not to buy anything. Then Stan gives them a "potion" that knocks them out and we get to see them wake up in the shack the day after, trapped inside a case and apparently glued to the stand, being shown off as an exhibit called "The Cheapskate". Kids show, right?
    • The above is made worse by Stan's continued creepy smile as the person's vision blurs and they fall over
      "You shoulda bought something while you had the chance..."
    • Arguably even creepier is what happens afterward: Mabel and Dipper see the person in there, and do not seem to care at all. Sometimes there's a thin line between Rule of Funny and Rule of Scary.
    • Though if the cryptogram at the end is to be trusted, this episode is non canon.
    • One of the items Stan talks about is this some... blob creature... with an unnatural appearance and high amount of eyes and other orifices.
    • The swarm of disembodied hands.
    • You thought the stop-motion monsters were creepy? Well, say hello to TO MABEL'S CREATION! THAT THING SHOULD NOT EXIST!!!
      • For those who don't know, Mabel conquers her fear of claymation and eventually changes the clay cyclops into something she likes. The end result is she ends up making the the Shimmery Twinkleheart, who is somehow even more terrifying rendered in claymation than in regular animation.
    • The entire use of claymation is in-universe Nightmare Fuel for Mabel.
  • Episode 7: "Society of the Blind Eye" features a secret society that has been erasing the memories of people in Gravity Falls, making them blissfully unaware and ignorant to the horrors and mysteries of the town.
    • To take it a bit further, it seems that various people of Gravity Falls suffer a bit of brain damage because of it.
    • Lazy Susan is seen on a payphone trying to call for help, when she's suddenly abducted by two members of the society, then they tie her down and erase her memory.
    • The scene where the main characters get to watch McGucket's memories is really unnerving, as it shows his descent into insanity, leading up for him to be the crazy old coot that we know him as now.
    • The credits scene shows Grunkle Stan, and he's working on his mysterious machine. A portal is open, sucking some things in, even a pipe which manages to hit Stan's hand (and we even get to see blood as he patches it up). Then there's some cryptic possible Foreshadowing as he says that no matter how dangerous this is or how long it takes, he will pull something off and no one will get in his way... right as the camera focuses in on a picture of Dipper and Mabel.
    • The first video journal of McGucket's show that something he worked on becomes more and more unstable as time passes. And at the very end, Stan comments that the portal is "growing stronger every day." The video diaries also reveal that McGucket worked on the portal with the author of the journals. This is a disturbing example of how erasing your memory many times due to denial can lead to complete and utter insanity.
  • Episode 8: "Blendin's Game" is probably the tamest episode of the season so far, but it still wasn't above showing the loser of a gladiator tournament screaming in agony as his body is disintegrated.
    • During the time travel segment, the Gleefuls can be seen walking by in the past, looking like a perfectly normal family... but there's also an advertisement that shows Bud having a 'just had a baby' sale. But someone drew on the advertisement, referring to Gideon as a 'demon' while drawing horns on him.
    • Beyond painful Foreshadowing, it just raises the question... What the hell happened? How did everything go so wrong...?
    • Blendin was going to Ret Gone Dipper and Mabel out of existence if he won.
  • Episode 9: "The Love God" could be considered a comic relief episode. However, it does place this show in rather stark perspective to realize that an episode that begins with an angst-ridden teenage boy moaning at the bottom of an open grave could be considered comic relief. Or that said comic relief includes a pair of cheerful undertakers who place plates of cookies on top of occupied glass caskets.
    • There's also Robbie's parents giggling as they exclaim that they hope nobody died in the balloon crash. Sure you do, your dread of the extra business is written all over your faces.
    • That open grave scene? It features the Mystery Shack kids encouraging Thompson to look inside by chanting "Gaze upon death! Gaze upon death!"
    • It's subtle, but the model of the town Mabel makes while trying to find a date for Robbie has a slightly unsettling resemblance to the one seen in Li'l Gideon's bedroom in "The Hand that Rocks the Mabel".
    • That horrible, HORRIBLE balloon created by Stan. It's deliberately over the top and darkly hilarious, but it just looks... wrong.
    • Robbie has a picture of Dipper on a dartboard. This isn't too weird, we've seen Bud Gleeful with a picture of Stan on a dartboard, the same with Pacifica Northwest and Mabel's picture. But Robbie's dartboard is filled with knives, and there's writing next to it reading DIE DIPPER DIE. It's quite unsettling, especially when you consider their age difference...
  • Episode 10: "Northwest Mansion Mystery" has the lumberjack ghost. Just the lumberjack ghost.
    • To herald his arrival to Dipper and Pacifica he had the stuffed animals head bleeding out of their mouths and eyes as they talked ominously.
    • After escaping from the mirror, he starts turning people into wood! And as if that weren't over the top enough, the final act of his rampage was to set the house on fire with all of the people turned wooden statues in it!
    • While everyone turning into wood by the Lumberjack Ghost was horrifying enough, we get a rather disturbing Call Back. When Dipper was turned into wood, his position and scream mirrors exactly how the Shapeshifter froze after transforming into him from Into The Bunker. What's even worse is that might not even be "his fate".
    • The very thing that Dipper screamed while he was becoming a wooden statue.
    Dipper: No, no, no, no, no! No! Someone help! SOMEONE HEEEELLLP...!
    • The fact that the Northwest parents and their butler were gonna let the ghost rampage and burn everyone else. Also, while it's more of dark comedy due to the delivery of the line, the fact that Preston was seriously planning on eating the butler once food ran out is still disturbing and just further shows what a depraved man he is.
    • There's some disaster that's coming in 21 hours, and a terrifying tapestry hints that Bill may be behind it!
      • Said tapestry seemingly depicting people worshiping Bill while being consumed alive by flames!
    • The ghost's backstory, good God. Did anyone actually expect we'd see that axe go flying at his head?
    • This one falls more under Fridge Horror, but throughout the episode, we see Preston controlling Pacifica (or at least, attempting to) by ringing a hand bell. What the hell did the Northwests do to their daughter to be able to keep her in line with a bell?! It probably has something to do with the fact that she found a gallery depicting the Northwests being a family of scum in "the worst chain in the world", and it's implied she was punished for it, but how is the question.
      • Pacifica only just discovered the gallery in this episode, but it's still heavily implied that her parents are abusive towards her, hence why they have her trained like one of Pavlov's dogs with a bell. Their Establishing Character Moment was yelling at her because she picked out a dress in a shade of green they didn't like. If she was that afraid to track mud on a certain carpet, then you can only imagine how deeply they've scarred her...and imagine how old she was when their abuse began. And as added Fridge Horror, consider what the Northwests were willing to let happen to avoid letting the townsfolk into their party: imagine what they're going to do to Pacifica for opening the gate.
      • They're not going to have time to punish her, the world's gonna end in 21 hours!
      • And the mural at the end heavily implying that the Northwests are either devout followers of Bill Cipher, or they're heavily involved with him in some form.
    • The Page Cryptogram at the end reads STANISNOTWHATHESEEMS STANISNOTWHATHESEEMS STANISNOTWHATHESEEMS! Now what is the name of the next episode? Not What He Seems. Oh, Crap!

I'll be watching you...
