A common assumption is that Creator/{{Disney}}'s Gravity Falls is strictly a kid's series. [[SurpriseCreepy After your first viewing,]] [[WhatDoYouMeanItsForKids you'll start to doubt that]].

[[folder:General]]
* The [[BlackSpeech 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.
** [[spoiler: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.]]
* [[spoiler: ''STAN IS NOT WHAT HE SEEMS'']]
* [[spoiler: [[EldritchAbomination 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 LoveToHate among the fandom, everything about him is unsettling at best and horrifying at worst. To elaborate:
** He's a [[spoiler: demon]]. No kid-friendly minced terms here, he's explicitly identified as a [[spoiler:demon]].
** He's '''completely insane''' and '''impossible''' to predict. Besides talking, his very first on-screen action was [[spoiler: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 [[spoiler: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 [[spoiler: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 [[spoiler:[[DemonicPossession take over your body]]. And he has ''no'' regard for your body's physical well being when he does so; quite the contrary, he [[TooKinkyToTorture goes out of his way to abuse it as much as possible]]]].
** He's always watching you. [[ParanoiaFuel Always]].
[[/folder]]


[[folder:Season 1]]
* Episode 1, "Tourist Trapped". A bunch of [[FairFolk 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". [[spoiler:Wax Sherlock Holmes tried to outright ''murder'' Stan with an axe.]]
** [[spoiler:[[FridgeHorror Had Mabel not made a Wax Grunkle Stan, the real Grunkle Stan might have met his demise...]]]]
** [[spoiler: HE'S STILL IN THE VENTS.]]
* 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 [[spoiler: ''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 [[WesternAnimation/TheMarvelousMisadventuresOfFlapjack 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...
** [[spoiler:'''POSSESSED MABEL''']]. It's creepy enough in concept, but actually ''seeing'' it...
** [[http://images2.wikia.nocookie.net/__cb20120605193113/gravityfalls/images/5/5c/S1e5_cooler_monster.png The cooler monster.]] ([[BigLippedAlligatorMoment Whatever happened to it, anyway?]])
*** It ''was'' presumably [[spoiler: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 ''[[AndIMustScream that's being cooked]]''.
** And judging by the sound effect and reactions of the characters watching, the cereal box one was a GoryDiscretionShot.
--->'''Cereal Box Bird''': I'm bonkers for eating you alive!
** More "GettingCrapPastTheRadar" 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. DarkerAndEdgier Disney indeed.
* Episode 6, "Dipper vs. Manliness" we're introduced to the leader of the manotaurs! [[spoiler: 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 [[spoiler: REGULARLY eat their own as offerings.]] It's implied that this isn't the first time this has happened. Doubles as a SugarWiki/MomentOfAwesome when he finally stands up to them however.
** When the Leader ''pulls a spear out of his chest'' with screaming and blood and everything. ''[[{{Squick}} 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, [[BodyHorror 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.
** [[spoiler: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 [[spoiler:the Time Baby, a large headed, [[RedEyesTakeWarning red eyed]] baby that seemingly controls all of time.]]
* Episode 10, "Fight Fighters", [[AdultFear lands Dipper in a shockingly realistic "fight with a bully" scenario]], especially by Disney Channel standards.
** Rumble [=McSkirmish=] on a rampage in the real world has some of this too, in retrospect. He's basically acting exactly like you'd expect a character from a fighting game to act when loosed in the real world (i.e. attacking everything in sight.) [[FridgeHorror Who's to say how many people might have gotten accidentally killed or maimed during this?]]
* Episode 11, "Little Dipper", has [[spoiler: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 [[spoiler:his mom, who seems to be very neurotic and dead-set on just vacuuming all the time. [[FridgeHorror Did Gideon drive her up the wall...?]]]]
*** He strikes some real {{Nightmare Face}}s, 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.
-->'''Gideon's mother''': ''[[MadnessMantra Just keep vacuuming just keep vacuuming just keep vacuuming...]]''
** 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 [[spoiler: 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 [[spoiler:[[Anime/SpiritedAway 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 [[DeadlyGaze 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 MindRape on this show.
* Episode 15, "The Deep End", features a lifeguard who is [[SeriousBusiness so dedicated to his job]] that it's almost creepy.
** The [[http://gravityfalls.wikia.com/wiki/File:S1e1_dipper_with_signs.png 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.
** Some of the creepy expressions Waddles makes while in Soos' body.
** When Soos tells [=McGucket=] that he's a man trapped in a pig's body, [=McGucket=] replies: "That's what they all say..." in a very unnerving manner, suggesting he's [[FridgeHorror eaten other talking animals.]]
** [[ImAHumanitarian McGucket telling Soos he'll still eat him in his human body.]]
* Episode 17, "Boyz Crazy." The sole fact that [[spoiler: 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=] [[spoiler: 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:
** [[spoiler: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 cuteness...it's really not pretty.
** Gideon's glowing eyes and freaky incantation while summoning Bill.
** Bill knows [[http://youtu.be/TvWFY6mJpWA?t=1m lots of things]]... '''[[VoiceOfTheLegion LOOOOOOOTS OF THINGS]]'''
** Remember how Gideon was once angry enough to try to cut out Dipper's tongue with lamb shears? Bill [[TheToothHurts 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. [[LaughingMad 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:''' '' '''EAT NIGHTMARES!''' ''
** 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.
** TheStinger 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.
*** If you look, you can see Bill's eye on some of the trees.
**** You can see his eye ''[[http://greenwithenby.tumblr.com/post/54901151462/hes-always-watching everywhere]]''
**** Take a look at Dipper's cap. [[FridgeHorror It's from the first episode.]]
** 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 a'''M'''."
-->"i don't give up answers easil'''Y'''.."
-->"i k'''N'''ow things. Fascinating things..."
-->"your reality is a game to me. And I like g'''A'''mes...."
-->"mischief is my '''M'''iddle name, but not my first....."
-->"th'''E'''re are six hints I will give you......"
-->"1. there is a secret soc'''I'''ety in Gravity Falls......."
-->"2. the Handyman know'''S''' more than he thinks........"
-->"3. gideon has '''B'''een searching for something........."
-->"4. what goes up '''I'''s sure to come down.........."
-->"5. dipper is p'''L'''aying with fire..........."
-->"6. i will be returning to Gravity Fal'''L'''s............"
* Episode 20, "Gideon Rises":
** The opening sequence.
** Gideon screaming at Waddles to get back in the corner, coupled with his terrified expression.
** [[spoiler: The giant robot Gideon]] definitely falls under UncannyValley.
** Gideon ''still'' retains his {{Yandere}} tendencies, and uses [[spoiler:the aforementioned Gideon robot to grab Mabel and demand she be his queen.]]
[[/folder]]


[[folder: 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 [[spoiler:He's not human, but a robot controlled by tiny little creatures.]] The huge [[spoiler:[[TheReveal reveal]]]] was really creepy and completely unexpected.
** And then [[spoiler:''they all [[GettingCrapPastTheRadar commit suicide]].'']]
--> [[spoiler: '''Creature 1''': The time has come, brother!]]
--> [[spoiler: '''Creature 2''': I can't! I have a family!]]
--> [[spoiler: '''Creature 1''': You signed the oath! ''(both swallow poison and die)'']]
* [[http://www.youtube.com/watch?v=96FEhn_N76Y The "Tooth" short.]] Or more specifically, the thing the tooth came from...
** [[spoiler: [[http://31.media.tumblr.com/3f972ba34bcb298717109a97b45936a6/tumblr_muu97iRipq1svxbupo1_500.jpg Here it is, if you're curious.]]]]
** The thing the tooth came from speaks backwards, and [[SchmuckBait if you are curious enough to translate it]]...
--> [[spoiler:"''You have disturbed my slumber. '''Enter my mouth, children! ENTER YOUR DESTINY!'''''"]]
** If you look closely when [[spoiler: 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.
* [[http://www.youtube.com/watch?v=NXrmRW_v1s8 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 [[http://gravityfalls.wikia.com/wiki/File:Shorts_the_hidden_page.jpg this wonderful image]].
** Not to mention when you decrypt the Red Code along the edge, it spells [[spoiler: 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.
[[/folder]]

[[folder:Shorts]]
* If you think about it for more than about a second, [[spoiler: 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 [[AdultFear big concern]].
* Octavia the 8-legged cow from "Mabel's Scrapbook". She looks harmless enough...until she zaps a passing eagle with her LaserEyes and eats it with her OverlyLongTongue.
-->'''Stan:''' ''Run.''
* We get more {{Yandere}} antics from our favourite CreepyChild in [[https://www.youtube.com/watch?v=E_9gA4qyU1k 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".
** [[https://www.youtube.com/watch?v=HlHE77GYhzs There's a sequel out now;]]
--->'''Gideon:''' [[spoiler: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 tickled...in your soul]].
[[/folder]]

[[folder:Season 2]]
* Episode 1, "Scary-oke", has a zombie invasion, [[spoiler:with poor Soos being infected and becoming a zombie.]]
** [[spoiler: Zombie Soos is made somewhat less terrifying by still being as goofy as he ever was.]]
** [[spoiler: The glove Stan puts on in the bunker has ''six fingers'']]
** [[spoiler: The blacklight reveals that there was blood on the journal's cover.]]
* Episode 2, "Into The Bunker" has the [[spoiler: Shape Shifter, which does [[VoluntaryShapeshifting exactly what its name implies.]] It tricks Dipper into thinking he's met the author of the journals, before revealing its terrifying, somewhat [[EldritchAbomination eldritch true form]] and trying to kill Dipper and take the journal. Dipper even discusses the fact that [[ParanoiaFuel if it got loose, it could turn into anyone and you would never know it.]]]]
** [[spoiler: 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 TrueNeutral, to the Summerween Trickster and Pa and Ma who have a FreudianExcuse, 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? ''[[http://i5.photobucket.com/albums/y188/Hikari_saito/BodyHorror.png (transforms into an BodyHorror mixture of the two)]]''
** [[spoiler: 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 [[OhCrap 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 [[BodyHorror notes from]] [[TheThing1982 another certain shape shifting alien...]].]]
** One of the worst parts about the [[spoiler: Shapeshifter? He makes the exact same sound effect as the [[WesternAnimation/BuzzLightyearOfStarCommand Zurg-a-Tronic Megaray,]] the source of many kids from the 90s nightmares.]]
** The overall similarities to [[TheThing1982 The Thing]] also add a lot of FridgeHorror. [[spoiler:Wendy's ''bleeding'' after the initial fight with the monster...]]
** Whatever that [[spoiler: monster in the shadows was. It appears to be a spider, but [[UltimateEvil we never actually see it in full form.]] It's also mentioned to have regenerative properties...]] This is assuming, of course [[spoiler: 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.]]
** [[spoiler: The Shapeshifter's last words.]]
-->[[spoiler: 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.'')]]
** [[http://gravityfallsnews.tumblr.com/post/94823732057/gravi-teamfalls-shapeshifter-transformations A few better looks at the Shapeshifter's transformation]]
* Episode 3: "The Golf War" was essentially a really funny, light hearted episode, but it did have two moments; when the Lilliputtians [[spoiler: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.
** Franz in particular, as performed by Creator/PattonOswalt, is just so cheerfully sociopathic in everything he says, and - unlike many of the other villains - [[BlueAndOrangeMorality barely seems to understand he's even doing anything wrong]].
* Episode 4: "Sock Opera". True to his word, [[spoiler:Bill Cipher has [[ParanoiaFuel been watching the twins]], and makes a return in this episode while being ''[[UpToEleven even creepier]]''.]]
** [[spoiler: 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 [[DoesThisRemindYouOfAnything way too much]] and his expressions when threatening Mabel are cruel in ways Dipper's face should never get.]]
** [[spoiler: Bipper wears this... GRIN on his face, half CheshireCatGrin, half SlasherSmile, and it's exceptionally creepy to look at.]]
*** The animators made [[spoiler:Bipper]]'s face more frightening than [[spoiler:Dipper]]'s could ever be by giving [[spoiler: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 [[{{Understatement}} more than a little]] [[UncannyValley disconcerting.]]
** [[spoiler: 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) SlasherSmile makes him look extremely sinister.]]
*** The character designers really went for the jugular with that one. WordOfGod is that [[spoiler: Bipper's mannerisms and reverend costume were based on two sources, Reverend Henry Kane of the ''{{Poltergeist}}'' film series and Reverend Harry Powell from ''NightOfTheHunter''. That's right, an eldritch cult leader and a serial killer who threatens children.]]
** [[spoiler: 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 [[spoiler: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 [[spoiler: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?
** "[[NightmareFace How can you do that...]] ''[[http://33.media.tumblr.com/4abcbd7cb0062ddc6c0b741172d83fe9/tumblr_nbmux2Iynt1qduyqso7_250.gif if you don't exist?]]''"
** Perhaps one of the more unnerving things about [[FanNickname 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 RealityWarper abilities convinced them all that was normal.
*** Interesting theory, but jossed: [[WordOfGod 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 PlayedForLaughs 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. [[https://33.media.tumblr.com/3b2c44516601ae1da9bee2c78ebd8027/tumblr_nbm5ped6sX1r2u7p0o1_500.gif 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.
** [[ParanoiaFuel "I've been keeping an-"]] ''*Bill briefly turns massive, red, and [[EvilSoundsDeep Satanically deep-voiced]]*'' "'''EYE ON YOU''' [[ParanoiaFuel since then..."]]
** Even the episode's code, once translated, makes an incredibly creepy poem:
-->''NO PUPPET STRINGS CAN HOLD ME DOWN''\\
''SO PATIENTLY I WATCH THIS TOWN''\\
''ABNORMAL SOON WILL BE THE NORM''\\
''ENJOY THE CALM BEFORE THE STORM''
** Makes you wonder what Bill's planning...
* Episode 5: "Soos and the Real Girl": The animatronics at the SuckECheeses 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 ''VideoGame/FiveNightsAtFreddys''.
** 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 [[spoiler: {{Yandere}} dating sim that ends up possessing the aforementioned animatronics to get to Soos and "delete" Dipper, Mabel and Melody.]]
*** Speaking of that [[spoiler: {{Yandere}} dating sim,]] how about the split-second NightmareFace [[spoiler: Giffany]] pulled after [[spoiler: Soos paused her and pulled out her disc to take it back to the game store?]] If there was any doubt about whether [[spoiler: 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. [[https://33.media.tumblr.com/0885483781afb1a4835e65e8e21516c3/tumblr_ncc988bRkL1tj7zngo1_1280.jpg 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.
*** [[UncannyValley 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 ContagiousAI powers and combined with her AccentOnTheWrongSyllable voice. Worse, apart from her brief screaming fit when she realized Soos was putting her up for a while, she never loses that [[FauxAffablyEvil cheerful, polite tone]].
** [[spoiler: 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 [[http://gravityfalls.wikia.com/wiki/File:Shorts_the_hidden_page.jpg 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 [[spoiler: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". [[WhatDoYouMeanItsForKids Kids show, right?]]]]
** The above is made worse by [[spoiler: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: [[spoiler:Mabel and Dipper see the person in there, and do not seem to care ''at all''.]] Sometimes there's a thin line between RuleOfFunny and RuleOfScary.
** 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 [[spoiler: TO MABEL'S CREATION! THAT THING SHOULD NOT EXIST!!!]]
*** For those who don't know, Mabel [[spoiler: conquers her fear of claymation and eventually changes the clay cyclops into something she likes.]] The end result is [[spoiler: she ends up making the [[ChekhovsGunman the Shimmery Twinkleheart]], who is somehow even '''more''' terrifying rendered in claymation than in regular animation.]]
** The entire use of claymation is in-universe NightmareFuel for Mabel.
* Episode 7: "Society of the Blind Eye" features a secret society that [[spoiler: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 [[spoiler: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 [[spoiler:two members of the society, then they tie her down and erase her memory.]]
** The scene where the main characters get to watch [[spoiler:[=McGucket=]'s memories]] is really unnerving, as it shows [[spoiler:his [[SanitySlippage 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, [[spoiler: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 [[spoiler:[=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 [[spoiler:[=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 ''RetGone 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. [[SarcasmMode 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 [[NotSoDifferent 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.
*** When all the taxidermied animals come to life during the party, we get lovely sights such as [[RaisingTheSteaks the front half of a deer dragging itself forward and a goat stiffly flailing on its side, as well as various animals attacking people while bound to pieces of wood.]]
** After escaping from the mirror, [[spoiler: 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 [[spoiler: turning into wood by the Lumberjack Ghost]] was horrifying enough, we get a rather disturbing CallBack. [[spoiler: 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 [[spoiler: becoming a wooden statue.]]
-->Dipper: No, no, no, no, no! No! Someone help! SOMEONE HEEEELLLP...!
** [[spoiler: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]].
** [[spoiler:There's some disaster that's coming in 21 hours, and a terrifying tapestry hints that Bill may be behind it!]]
*** [[spoiler:Said tapestry seemingly depicting people worshiping Bill while being ''consumed alive by flames!'']]
** [[spoiler: 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 FridgeHorror, 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?! [[spoiler: 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.
*** [[spoiler: Pacifica only just discovered the gallery in this episode]], but it's still heavily implied that [[spoiler: her parents are abusive towards her, hence why they have her ''trained like one of Pavlov's dogs'' with a bell. Their EstablishingCharacterMoment 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 FridgeHorror, 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.]]
*** [[spoiler: 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 [[spoiler: the Northwests are either devout followers of Bill Cipher, or they're heavily involved with him in some form]].
** The [[FreezeFrameBonus Page Cryptogram]] at the end reads [[spoiler: [[MadnessMantra STANISNOTWHATHESEEMS STANISNOTWHATHESEEMS]] [[RuleOfThree STANISNOTWHATHESEEMS!]]]] Now what is the name of the next episode? [[spoiler: Not What He Seems.]] OhCrap!
