[[folder:S]]
* SacredScripture: The hero's handbook, ''The Enchiridion'', a legendary book that tells you how to be a hero, is not called "sacred", but it's treated as so important it might as well be.
* SadisticChoice: The guardian of the wishes in "The Limit" ''tried'' to force Finn to make one of these and choose between saving Jake and the psychic tandem war elephant he and Jake went through the maze to get. [[spoiler:Finn wished for the elephant, got control of it and then had ''it'' wish to save Jake and fly them out.]]
* SanitySlippage:
** Jake in "Gut Grinder".
-->'''Finn:''' You are ''crazy'', dude! Like, actually ''crazy''.
** Also, Bubblegum towards the beginning of "The Duke".
---> '''Bubblegum:''' (''[[LaughingMad insane laughter]]'')\\
'''Jake:''' Ha ha, she's completely bonkers...
** Jake again in "No One Can Hear You", to creepy levels.
** Revealed to be why [[spoiler:Ice King]] is the way he is.
** Happens in "Jake the Dog" to [[spoiler: AU!Finn after he puts on the Ice King's crown.]] 
** The episode "You Made Me!" is basically one big one for Lemongrab.
** Sleep-deprived Princess Bubblegum in "Goliad":
-->'''PB:''' I'm not gonna live forever Finn. *Whispers* ''I would if I could.'' But modern science just isn't there yet.
-->'''PB (explaining the process of creating candy life):''' Oh, um... Pretty standard candy creature soup. Some acids. Some algebra. And I threw in one of my baby teeth so she had my DNA.
-->'''Finn and Jake:''' Wow, DNA?!
-->'''PB:'''Yeah. All it takes is just one little tooth, or a single hair. It's ''all'' it takes..." She trails off, suddenly brushing thin air after Goliad moves the paw PB had been brushing.
* SarcasmMode:
-->'''Finn:''' I shall conquer my fear.\\
'''Fear Feaster:''' Yeah, ''right''...\\
'''Finn:''' I will! I'll conquer my fear!\\
'''Fear Feaster:''' Of ''cooouuurse'' you will, and I live in a two bedroom apartment that doesn't smell like vomit. [[EvilLaughter Hahahahaha]], ''sarcasm''...
* SassyBlackWoman:
** [[RuleSixtyThree Cake]] seems to be this even though she's a cat.
** According to Jake, Tree Trunks.
--> "I can't hold her! She's too strong and sassy!"
* SatelliteLoveInterest: Brocko is one for Princess Bubblegum. Lampshaded with his in-commercial catch phrase "I was born to date the princess."
* SaveThePrincess: Played straight most of the time. Inverted in "Dungeon". [[SpearCounterpart Gender-inverted]] in "Fionna and Cake". Inverted again in Lady and Peebles.
* SayMyName: A RunningGag in "Wake Up" and "Escape From the Citadel." See also the ScreamsLikeALittleGirl entry below.
--> '''[[WellDoneSonGuy Finn:]]''' [[BattleCry DADDYYYYY!]]
* SayingSoundEffectsOutLoud: Ice King from time to time. 
-->'''Ice King:''' ''ZAP!!''
* SceneryCensor: A more literal example for the scenery itself: F&J have a painting of a woman in the treehouse with a large ripped section, which alludes to possible nudity underneath. That said, WordOfGod indicates that she isn't naked after all.
* SceneryPorn[=/=]SceneryGorn
* SchizoTech and ScavengerWorld: UpToEleven on both counts, and justified in that this show takes place after a nuclear war that wiped out technology and made everything into a magical fairy tale world.
* ScreamsLikeALittleGirl:
** Finn in "Power Animal" and "Burning Low". Jake in "Evicted".
** Flambo in "Incendium."
--->'''Flambo:''' Yeah, it's me. [[LampshadeHanging Bet you thought I was a dame on account of my girlish screamin']].
** Lemongrab displays an interesting variation of this. He's ''usually'' screaming in a high-pitched, almost feminine way. It would be notable to list all the times he ''doesn't'' do this.
** Finn does this more than once because of Princess Bubblegum, and it becomes a running joke in "Burning Low".
* ScrewDestiny: Finn does everything in his power to prevent Jake's prophesied death. [[spoiler:He succeeds.]]
* ScrewThisImOuttaHere:
** When Princess Bubblegum [[spoiler: emerges from her operation as a thirteen year old]] in "Mortal Recoil" Ice King immediately loses all interest and flies out the nearest window.
** Near the end of "Belly of the Beast", Jake decides that he's had it with Party Pat and goes off to watch TV. 
* SealedEvilInACan:
** The Lich was sealed away in amber by Billy, and it was for the good of everyone, as the Lich is an OmnicidalManiac seeking to destroy all life. [[spoiler: He mind controlled the easter egg snail and got free.]]
** Marceline's Dad is the ruler of the Nightosphere, which also appears to be the original home of the Abadeer family (family photos of Marceline, Hunson Abadeer, and Marceline's mom can be seen inside their home; Hunson also wanted Marceline to take over ruling the Nightosphere because it's the family business). The only catch is that Hunson is unable to leave the Nightosphere without outside assistance, playing the trope straight, except with an added LuxuryPrisonSuite angle.
* SealedEvilInADuel: [[spoiler:Stormo, a Candy Spinx created from Finn's DNA to combat the evil, power mad Goliad, traps Goliad in a psychic duel for all eternity.]]
* SecretDiary: Or it ''is'' secret until Finn and Jake find it in his (the Ice King's) room. 
* SecretTestOfCharacter:
** Refusing to "Slay this unaligned ant!", and attacking the test-giver instead was the correct answer to Finn's last test before claiming the Heroes' Enchiridion.
** "Dad's Dungeon" had elements of this until Jake, who know everything that is going on, tells Finn.
** Inverted with the Magic Man. His test is about ''not'' helping others. Finn fails at first.
* SecurityCling: Finn and Princess Bubblegum, to each other, on pages 404 and 436 of [[http://www.scribd.com/doc/19328046/Slumber-Party-Slaughter-Storyboard this storyboard]] for "Slumber Party Panic". Left out of the actual episode, however.
* SeeYouInHell:
** Finn says, "I'll see you in the Nightosphere, you sick freak!" very darkly right after he sends Marceline's soul sucking Dad back to the fiery pits of the Nightosphere.
** In "Hug Wolf", Jake pulls this on the Tree of Blight as he burns it down:
-->'''Jake:''' When you see the wicker devil in tree afterlife, tell 'im Jake says, "Hello."
* SelfGuardingPhlebotinum: In "City of Thieves," the King of Thieves' tower has a barrier around it that repels all thieves.
* SequelEpisode:
** Season two's "Crystals Have Power" for [[spoiler: "Tree Trunks".]]
** The episode "The Creeps" touches on events that occurred in "Mystery Train".
** "From Bad to Worse" is this for "Slumber Party Panic".
** "Beautopia" for "Susan Strong".
** The season four episode [[spoiler:"Hot to the Touch"]] for "Incendium".
** The Nightosphere two-parter ("Return to the Nightosphere" and "Daddy's Little Monster") this for "It Came from the Nightosphere".
** "You Made Me!" for "Too Young". The episode "Too Old" is also a sequel of sorts, containing many call-backs to "Too Young".
** "Finn the Human" and "Jake the Dog" form a two-part episode following up on the cliffhanger ending of "The Lich".
** "You Made Me!" got its own sequel "All Your Fault."
** "The Great Bird Man" for "The Silent King."
** "Simon and Marcy" for "I Remember You"
** "Sky Witch" for "What Was Missing" as well as for "Memory of a Memory"
** "The Creeps" received it's own sequel, "The Vault"
* SerialEscalation:
** In terms of creepiness. Name anything creepy about this show--the MindScrew ending of "Tree Trunks" and "Evicted!", the {{Nightmare Face}}s Marceline, Peppermint Butler's desire for flesh--it doesn't matter. ALL of that was topped by '''[[http://static.tumblr.com/nxveby3/K7nluq5f7/tumblr_luonoxu9hq1qeyb9ho1_500.gif this.]]''' Holy. Freaking. ''Crud''. According to Adam Muto, ''[[http://www.formspring.me/MrMuto/q/260624254293255046 this is just the beginning.]]''
** They outdid themselves ''again'' with those [[MonsterClown creepy freaking clown nurses]] in "Another Way", which ''legitimately'' freaked out most people who watched the episode and [[http://26.media.tumblr.com/tumblr_lyac9nt7SL1qftn52o1_500.gif undoubtedly scarred many children for years to come. Prepare to lose sleep.]]
** They did it again with those [[spoiler:three freaking scary fruit witches in "Dad's Dungeon", two of whom ''ate the third voraciously''.]]
** A separate example from above from the Season 5 two-part opening: [[spoiler:[[FromBadToWorse How much worse is it going to get]] for AlternateUniverse Finn in Farmworld? First he is forced to sell his pet to pay back a gang, then tries to find a way around it, then comes across the Ice King's crown which an elderly and insane Marceline warns him to avoid, then gets it stolen by Big D, the gangster threatening his dad, then finds that while he was fighting Big D to get it back, the gang set his hometown on fire, then goes home to find that his house is burning with his family in it, then in desperation puts on the crown, which saves his house by freezing it but drives him insane, ''then'' he tries to stop the town from burning and [[ApocalypseHow sets off the atom bomb,]] ''then'' finds his family but has to send them away so he can't hurt them (even though they are probably going to die of radiation in the next few hours), then finds that he's killed Jake with the bomb as he's in a pool of radioactive goo, '''''and then''''' has to fight him as he is turned into the Lich via radiation. It would presumably get even worse had Jake not cut it off by wishing them back home.]] '''''NiceJobBreakingItHero!'''''
* SeriousBusiness: "2 + 2. SOLVE IT OR DIE."
* ShadowDiscretionShot: Is used in "Escape From the Citadel" when [[spoiler: The Lich unwillingly grows back his flesh when Finn flings some Ancients' blood at him. ]]
* ShaggyDogStory: "The Box Prince." Finn goes to great lengths to assist a cat prince in retaking his cat kingdom...only to have everyone (including the prince himself) just wander off indifferently when it's done. [[FridgeBrilliance It's a kingdom composed entirely of cats.]] They don't ''care''.
-->'''Finn:''' Is this...is this even a kingdom?

* ShamefulShrinking: Jake used his shapeshifting powers to do this literally when attention was called to him for the fact that it'd been his words that caused Finn to make a party uncomfortable.
* ShiftingSandLand: The Desert... of '''[[DoomyDoomsOfDoom Doom]]'''.
* {{Shipping}}: Amazingly, done ''[[InUniverse in-universe]]'' by Finn in "All the Little People."
* ShipSinking:
** Marceline dispels any implications of her getting with Finn any time soon in "Go with Me".
** [[spoiler:In "Too Young", PB turns 18 again. She says that Finn should just move on because "That was 5 years ago!"]] Which is even more spiteful than the above example, considering the episode up until that point was ShipTease upon ShipTease. [[spoiler: [[TimeyWimeyBall Issue 8 of the comic]] directly references this ShipSinking and plays with it.]]
** [[spoiler:In "Fionna and Cake", Fionna sinks the Fionna/Gumball ship when she realizes that she's not interested in dating him.]]
* ShipTease:
** The entire plot of "Go With Me", up until the [[ShipSinking Ship Sinking]] by Marceline mentioned above. Note that relationships with both Bubblegum ''and'' Marceline were teased throughout the episode, only to be put down... [[spoiler: until "Mortal Folly" and "Mortal Recoil" in which the amount of teasing for Finn and Bubblegum's relationship ''skyrocketed.'']]
** The entirety of "Too Young" was one huge tease for Finn x Bubblegum, [[http://www.flickr.com/photos/84568447@N00/6012011495/in/photostream/ even the title card]], [[spoiler: until the ending]].
** "What Was Missing" had ''a lot'' of this for Bubblegum x Marceline, and at the same time, more for Finn x Bubblegum.
----> ''~What am I to you? / Am I a joke, your knight, or your brother? / What am I to you? / [[CallBack Do you look down on me 'cause I'm younger?]]~''
** "Burning Low" provides a new ship: [[spoiler: Finn/[=FlamePrincess=]]]
** "Gotcha!" teases a bit of Lumpy Space Princess/Finn, oddly enough.
** If you can believe it, "I Remember You" had a brief one for [[spoiler:Marceline and Ice King]]... before it turns into ShipSinking as [[spoiler: she sees him as her surrogate father]].
** Marceline's story in "Bad Little Boy" [[spoiler: is built around Fiona/Marshal Lee teasing.]]
** "Sky Witch" has a lot of ''blatant'' teasing for Bubblegum and Marceline so much so that its almost a parody.
* ShrinkingViolet: Raggedy Princess. She spoke for the first time in the series to Finn in "Mortal Recoil" when she brought him his [[spoiler:new]] backpack.
* ShockCollar: Lemongrab has his subjects wear them in "Too Old".
* ShotaCon: Finn and Tree Trunks.
* ShoutOut: Has its own [[ShoutOut/AdventureTime page]].
* ShowWithinAShow: ''Heat Signature.''
* ShutUpHannibal: Brief one given by Finn to the Lich, which [[spoiler: snaps Finn out of the Lich's mind control.]]
--> '''Lich:''' Aren't you cold, Finn?\\
'''Finn:''' ...NO, I'M NOT! I'VE GOT A ''SWEATER ON!!''
* SimilarSquad: Billy, when compared to Finn. His main adversary was the Fire Count, from whom he rescued a Cotton Candy Princess, and he had a magical dog. To top it off, both got hair as a gift from their respective princesses and both fought the Lich.
* SingleTear: The Ice King has one at the end of "What is Life?" As of "Reign of Gunthers" and "I Remember You," both Gunter and Marceline have one respectively.
* SinisterGeometry: Subverted in the Soft People, the Cube People, and Spiky People. They're actually pretty nice, but the Spikey People love group hugs.
* SinkOrSwimMentor: Jake, in the episode, "Ocean of Fear."
* SittingSexyOnAPiano: Tree Trunks in the title card for [[http://www.flickr.com/photos/84568447@N00/4506683898/ "Tree Trunks".]]
* SkeletonKeyCard: The Ice King uses a credit card to unhook the latch on Bubblegum Princess' shutters in "Mortal Folly".
* SlasherSmile: Princess Bubblegum gets this when considering the idea of bringing the Duke of Nuts to justice.
* SleepCute: Finn and Jake, at the end of "The Eyes." Honorable mention to the Ice King. Finn mentions in "Gut Grinder" that he watches Jake when he sleeps, no doubt due to this.
* SlidingScaleOfComedyAndHorror: Nicely balenced, with [[SugarWiki/FunnyMoments hilarious]] and [[NightmareFuel horrifying]] moments.
* SlowMotionDrop:
** There's one for Finn's tear at the beginning of "Crystals Have Power".
** There's also one for Lumpy Space Princess's beans in "Heat Signature".
--->'''Lumpy Space Princess:''' MY '''''BEEEEAAANS!!!'''''
* SmashingHallwayTrapsOfDoom: The Clashing Gates from "Beautopia".
* SmoochOfVictory: Finn's usual reward for [[SaveThePrincess saving a princess]]. Princess Bubblegum has kissed him ''four'' times and counting. (Go Finn!)
* {{Snapback}}: [[LampshadeHanging Lampshaded]]!
-->'''Finn:''' (after a scene transition) Ah...everything's back to normal.
* {{Snowlems}}: Finn and Jake encounter one in the pilot cartoon.
* SolarPoweredMagnifyingGlass: In an AdBumper, the Ice King uses a magnifying glass to try to kill a giant ant. He threatens to use it on Finn.
* SoulJar: [[spoiler:The Fight King's sword]].
* SpaceWhaleAesop: In universe, lampshaded at the end of "Slumber Party Panic":
--> '''Princess Bubblegum:''' I hope you grasp the full consequences of breaking promises.\\
'''Finn:''' Heck yeah! If I break a Royal Promise, I get to fight zombies, throw slumber parties, awake Gumball Guardians, and -- and --\\
'''Princess Bubblegum:''' All right, all right!\\
'''Finn:''' -- and ''REVERSE DEATH ITSELF!''
* SpaghettiKiss: Happens with Little Finn and Little Flame Princess when Finn gives them a cookie to share in "All the Little People".
* SpecialEditionTitle:
** "Fionna and Cake" had every character who appears in the opening replaced by their gender-swapped counterpart. Even the singer of the theme song was changed from a male one to a female.
** "A Glitch Is a Glitch" gives us the opening completely CGI animated.
** Multiple guest stars have actually appeared on ''Adventure Time'' but it seems only NPH's appearance was publicized. Other people that appeared on the show were Music/GreyDeLisle as the Ice Queen, [[Series/TheIncredibleHulk Lou Ferrigno]] as Billy, MarkHamill as The Manifestation of Fear/Fear Feaster and the Dark Magician in "The Enchiridion!", Andy Milonakis as NEPTR, Martin Olson as the father to her daughter's role of Marceline, Ron Perlman as The Lich, Henry Rollins as Bob Rainicorn, Andy Samberg as Party Pat, Laura Silverman as Ethel Rainicorn, Kumail Nanjiani as Prismo, and GeorgeTakei as Ricardio.
** Music/WeirdAlYankovic as the Banana Man in "New Frontier", though he spoke mostly in grunts. He appears again in "We Fixed A Truck", this time with a lot more lines, and he even gets to [[ActorAllusion sing]] at one point.
** Music/ChildishGambino a.k.a Donald Glover as Marshall Lee in "Bad Little Boy".
** At least two StarTrekTheNextGeneration alum cameos so far: Creator/JonathanFrakes as adult Finn in "Puhoy" and Marina Sirtis as Samantha in "The Pit." Peculiarly, the former episode closely parallels the plot of "The Inner Light". In "BMO Lost", Bubble is played by LeVarBurton.
* SpecialPersonNormalName: Billy and Jake mostly.
* SpeciesSurname:
** Both Finn and Jake have these. Also Mr. Fox, Mr. Goose, and Mrs. Cow from "Storytelling".
** It seems all Rainicorns share this trait.
* SpiderSense:
** Jake has the ability to sense when Finn is about to cry. "It's kind of a [[MamaBear mother/daughter]] thing", apparently.
** His GenderFlip counterpart Cake also has a spider sense. When her tail frizzes, she senses trouble.
* SpiritualSuccessor: To SpongeBob SquarePants, which the majority of the writers worked on before it was cancelled in 2004 (Though it was UnCancelled 5 years before Adventure Time premiered).
* SpitefulSpit: Marceline does this to PB in "What Was Missing". Needless to say, she [[{{GASP}} gasped]]. ...[[ExaggeratedTrope A lot.]]
* SplitScreenPhoneCall: In "Go With Me" between Finn and Princess Bubblegum then between Jake and Marceline.
* SpoilerTitle:
** There is a season four episode called... "The Lich". [[SarcasmMode Do you think it has something to do with the Lich?]]
** "Jake the Dad."
* SpoofAesop: Taken pretty much any Aesop the show presents, a more blatant example is a wizard turning people into body parts and not turning them back until they realized how much of a jerk he was. The message here ("some people are jerks and not worth your time") isn't necessarily a joke, but it's pretty pointless considering you can't tell if someone's going to screw you over until you try to help them out.
* SqueakyEyes: Finn has fun with this in "The Real You".
* StandardHeroReward: Slime Princess tries to do this with Finn, to his dismay. HilarityEnsues.
* StarCrossedLovers: Finn and Flame Princess. Especially since she seems to think that he's a [[ElementalEmbodiment water elemental]].
* StartOfDarkness: The episodes [[spoiler: "I Remember You" and "Simon and Marcy"]] for the Ice King.
* StatusQuoIsGod:
** In "When Wedding Bells Thaw", Ice King almost gets married to Old Lady Princess, but it turns out he had [[MindControl cursed her]] so she would marry him. Finn and Jake foil the marriage, and it's back to capturing princesses for the Ice King.
** Also occurred in "Too Young", when [[spoiler: Princess Bubblegum, who was transformed into a 13 year-old at the end of the last season, had to be transformed back into an 18 year-old in order to reclaim the kingdom from the Earl.]]
** In the two parter, "Finn the Human" and "Jake the Dog" [[spoiler:the whole universe goes awry and creates another timeline in which Finn and his human family live in Farmworld and are tormented by the Destiny Gang. This goes as far to the point where Finn has the Ice King's crown and Jake becomes the/a Lich due to the atomic bomb before Prismo encourages Jake to wish that the Lich wishes them back to Ooo.]]
** In "Jake the Dad", Jake decides to live with Rainicorn [[spoiler:to raise their pups. Turns out Rainicorn's species matures very quickly. Jake moves back in with Finn since his children are full-grown and don't need him to take care of them anymore. Plus all his stuff is with Finn anyway.]]
** In "Breezy", [[spoiler: Finn's right arm grows back with the help of the eponymous bee.]]
* StayInTheKitchen: One of the many reasons why [[spoiler:Marceline's ex, Ash]] is a dick.
* StealthPun: 
** Death in, "Death In Bloom", does a Death Metal drum solo in a music duel with Finn.
** Also, Finn wanted to throw never-ending pies at Jake's face. Think about it. [[DontExplainTheJoke Pi is a never-ending decimal.]]
** "The Great Bird Man": Xergiok feels himself hitting bottom again.
* SteamPunk / DieselPunk: The [[spoiler: alternate universe]] shown at the end of "The Lich", and in "Finn the Human" and "Jake the Dog".
* SteppingStoneSword: In "The Eyes", Finn's sword gets stuck in the wall. Jake uses it as a springboard to jump off and attack the Ice King.
* StockholmSyndrome: Finn, Jake and the Princesses fake this in order to escape from the Ice Kingdom in "Prisoners of Love".
* StockScream: There's a Wilhelm scream at the very end (right at the cut to black after Finn and Jake are seen on the dolphin's back) of "Memories of Boom Boom Mountain".
* StressVomit: In the episode "Jake the Dog", Jake vomits after realizing the gravity of the present situation: his wish to Prismo is the only chance he has to save the world, and he has to be specific, or else [[LiteralGenie there could be disastrous consequences]].
* StuffBlowingUp:
** The episode "Slumber Party Panic" reveals that [[AnthropomorphicObjects candy people]] explode when they're scared. Thankfully, the effect appears to be reversible since poor Starchy is just fine at the end.
** When the Lich reaches his power well in "Mortal Folly", a [[DisasterPorn particularly impressive]] ''green'' explosion occurs.
** When [[spoiler: Clarence]] finds out he [[spoiler: killed Warrior Princess]], he binges on spray cheese. So much so he explodes. No wonder Jake didn't like spray cheese.
** The little cuties from "Cute Conquest" tended to explode for no reason. One of their handicaps as would-be conqeurors.
* StylisticSelfParody: How Jake [[LampshadeHanging Lampshades]] the fact that [[TheNoseless Finn doesn't appear to have a nose]].
-->'''Jake:''' Bet ''you'' wish you had one, right?
* StylisticSuck:
** Usually averted: since the show takes place AfterTheEnd, it would make sense for no one to really know how to properly play instruments, but some characters are decent musicians (Ice King, Jake, Marceline...)
** Parts of "Adventure Time With Fionna and Cake" are written like a FanFic. [[spoiler:Because it is.]]
** The show as a whole, actually! Pen's artistic style calls for everyone to look extremely simplistic and lazily designed (almost a laid-back style) with no joints for characters' noodley limbs and faces that could be summed up as "two dots and a line". The storyboarders just roll with it and ''still'' manage to make everything look pretty damn impressive.
* {{Subtext}}:
** A lot in the first season, before the post-apocalyptic setting was fully obvious. The episode "Tree Trunks" may have had some concerning death, senility, and aging (it certainly spawned multiple theories about how the show was a dream playing out Finn's psychoses and subconscious fears, so there's something there). "The Jiggler" also had a lot about parental abandonment. In general, the show's love of DoesThisRemindYouOfAnything combined with Finn's status as a young, traumatized orphan leads to a lot of unsettling imagery.
** It's very apparent in the season 4 premier, "Hot To The Touch." The entire episode consists of Finn running doggedly after Flame Princess because he "like" likes her while Flame Princess is trying her damnedest to make Finn pay for "hurting" her and toying with her emotions (which was Jake's doing, no less). In what has to be one of the show's sadder moments, Finn defeatedly asks himself why he can't just like a normal girl while breaking down into tears. This seems to grab Flame Princess's attention, who (mistakenly) believes Finn to be a water elemental; hence why even if the two did care for each other, they could never be together because they'd only hurt one another. Anybody who's ever loved someone that either just wasn't good for them or hurt them badly can understand this very adult problem and will probably shed a tear or two when they see it for the first time.
* SubvertedCatchPhrase: In "Slumber Party Panic". Finn says "What time is it?" to Jake, who questioningly replies "Adventure Time?" Finn replies, "No, it's time for Seven Minutes in Heaven."
* SubvertedKidsShow: [[PlayingWithATrope Sort of.]] While it is still a kids show [[WhatDoYouMeanItsForKids technically,]] it is not as bright and colorful as it seems on the surface; the show's liberal use of ArtStyleDissonance, BlackComedy, BackstoryHorror, {{Subtext}}, [[NightmareFuel/AdventureTime Nightmare Fuel]], FamilyUnfriendlyViolence, {{Spoof Aesop}}s, SelfParody, and GettingCrapPastTheRadar would place it pretty firmly in this category were it not for the fact that it's still a TVPG kids show on Creator/CartoonNetwork, if only barely. So it's kind of a DoubleSubverted kids show.
* SuckinessIsPainful: In "Storytelling" Finn's sucky story-telling only makes Jake even ''more'' sick.
* SugarAndIcePersonality: Ironically, Flame Princess.
* SugarBowl: The Land of Ooo is a parody of one. See SubvertedKidsShow above.
* SummonBiggerFish: In "Hitman", The Ice King hires a hitman to literally hit Finn and Jake for grounding him. However, when Ice King is told that the hitman would actually ''kill'' Finn and Jake, and is unable to call him off, he hires a hit-hitman to take out the first hitman. [[spoiler: Surprisingly, this results in a CurbStompBattle with the first hitman easily killing the hit-hitman, making this a subverted trope.]]
* SummoningRitual: To summon Marceline's father from the Nightosphere, Finn draws a circle with a happy face (as mentioned above in GeometricMagic), pours bug milk on it, and gets Marceline to say a [[AltumVidetur Latin]] [[MagicalIncantation incantation]].
* SuperPowersForADay: Finn and Jake get wizard powers in "Wizard", ranging from controlling shadows to generating ''mayonnaise''. According to WordOfGod, [[ClothesMakeTheSuperman they lose them at the end of the episode when their robes are destroyed]]. Here are some of the powers:
** CastingAShadow: Shadowcery.
** {{Deflector Shield|s}}: Reflect.
** {{Flight}}: Beauteous wings.
** HavingABlast: Creating fireworks.
** NaturalWeapon: Tiger claws.
** {{Whatevermancy}}: Dustomancy.
** WreathedInFlames: Blazing feet.
* SurrealHumor
* SuspiciouslySpecificDenial: After Jake beats Finn in a tough guy contest.
--> '''Finn:''' Ha! You didn't mash my potatoes! You didn't even make me cry silently into my pillow last night for thirty minutes...
* SwallowedWhole: Finn, Jake, and the bears in "Belly of the Beast".
* SwiperNoSwiping:
-->'''Jake:''' The [[NinjaPirateZombieRobot bazooka goblin]] has you in its sights!\\
'''Finn:''' HEY! Don't shoot us with that bazooka!\\
'''Bazooka goblin:''' ''(giggling)''\\
'''Finn:''' Don't you do it...\\
'''Bazooka goblin:''' ''(still giggling)''\\
'''Finn:''' DON'T DO IT, MAN!\\
'''Bazooka goblin:''' Hehehehe... ''(beat)'' Okay.\\
'''Finn and Jake:''' Haha, YEAH! ''(fist pound)''
* SymbolicBlood: The Jiggler's juice in the title card for "The Jiggler".
[[/folder]]

[[folder:T]]
* TakeAThirdOption: In "Another Way", Finn comes to a fork in the road, and is given the choice to go down a path that will make him lose his hair forever, and a path that will make him smelly forever. What does he choose? ''His'' way: going through the thorn bushes in the middle. In fact that episode is entirely about that in that Finn sets out on his quest 'because' he'd rather take the third option, further the episode both subverts this trope briefly and then plays it straight towards the end.
* TakeOurWordForIt: A short instance of it in "It Came from the Nightosphere" when the Lord of Evil leaves Marceline's house, and another when he shows Ice King his NightmareFace, causing Ice King to [[BringMeMyBrownPants soil his tunic]].
* TakeOverTheWorld: Ice King's goal in "Loyalty to the King".
* TalkingAnimal: "Storytelling" shows that most if not all animals are capable of speech.
* TheTapeKnewYouWouldSayThat: Played with in Joshua's pre-recorded messages.
-->'''Jake:''' But dad, Finn's already figured that out. He's a good kid with a kind heart.\\
'''Joshua:''' Remember, Jake, this is a pre-recorded holo-message. I can't hear you if you're talking to me right now.\\
(Moments later...)\\
'''Jake:''' But--\\
'''Joshua:''' BUTTS ARE FOR POOPING!
* TeamShot: The picture on the main page.
* TechnoBabble: A forte of Princess Bubblegum and Ricardio.
--> '''Ricardio:''' The plasmordial layer is completely independent of the Babylons.\\
'''Princess Bubblegum:''' Wow! That would mean that the Babylons would fluctuate with the piranhananosphere!\\
'''Ricardio:''' Correct.\\
'''Finn:''' They're talkin' about science, man. I can't compete with that!
* TeensAreMonsters: Marceline and Jerky Teenage Bear.
* TemptingFate: There's this from "Belly of the Beast":
--> '''Jake:''' Seriously, the only foreseeable threat might be all these trees being swallowed, but they're not hurtin' nothin'.\\
'''Finn:''' Yeah... Good thing [the monster's] not swallowing some deadly volcano lava. That would kill them for ''sure''!\\
[[spoiler:''(The monster considers this and heads for a volcano.)'']]
* TheFinalTemptation: Puhoy. A Tearjearker as well. It's both played straight, subverted and then played straight again.
* ThemeTuneRollCall: "...With Jake the Dog and Finn the Human..."
* TheyJustDontGetIt: The bears in "Belly of the Beast" simply don't understand that they will be digested if they stay in the giant's belly.
* [[TheyWastedAPerfectlyGoodSandwich They Wasted A Perfectly Good Burrito]]: Dang it, Jake!
* ThinkingUpPortals: The Door Lord from "What Was Missing".
* ThisLoserIsYou: Arguably, the Ice King at the ending of [[spoiler:"Fionna and Cake" is supposed to resemble shippers and fan fic writers in general.]] [[AffectionateParody All done in good fun, of course.]]
* ThoseTwoGuys: The two gumdrop girls. They're frequently seen in the background, almost always seen together, and have had absolutely no impact whatsoever on the plot.
* ThrillerOnTheExpress: "Mystery Train"
* ThrowTheBookAtThem: Finn throws the Enchiridion at a worm in "Evicted!".
* TinyGuyHugeGirl:
** Lady Rainicorn's parents
** Jake and Lady are typically this, but Jake has used his stretching powers on 1 or 2 occasions to be the bigger one.
* TitleDrop: The term "Adventure Time" serves as the eponymous duo's catch phrase, lead into by Finn saying "What time is it?".
** There are also permutations of it in a few episodes. "Slow Love" saw "Lady Time", "The Dungeon" featured Jake joyously proclaiming it to be "Lunch Time," and "Susan Strong" has Finn help Susan using "Incremental Time."
** There are a few "episode" title drops like in "Loyalty to the King", "What Have You Done?", "The Real You", and "Go With Me".
*** From "Too Young":
---->'''Lemongrab:''' TOO YOUNG! TOO YOUNG TO RULE THE KINGDOM! 
*** And now we have this from "Too Old", which featured a number of call-backs to "Too Young" (as the name suggests):
---->'''Lemongrab:''' YOU'RE TOO OLD PRINCESS! TOO OLD FOR PRANKS! ''TOOO OOOLLLDDD!''
** Parodied in-universe in "Heat Signature" for the movie ''Heat Signature''. Try to figure ''that'' out.
--->"AAAH, MY HEAT SIGNATURE!!"
** "YOU MADE ME LIKE THIS! YOU MADE ME! ''YOOOU MAAADE MEEE!''"
** "IT'S ALL YOUR FAULT! ''ALL YOUR FAULT!''"
** The Lich drops the title of "Wake Up" to [[spoiler: Old Man Prismo, just before killing him.]]
* TogetherInDeath: Ghost Princess and Clarence fall in love ''while'' they are ghosts in "Ghost Princess". Eventually, though, the trope is [[spoiler: played straight when it is revealed Clarence killed Warrior Princess in a war]].
* ToiletHumor:
** The penalty for stealing boots in "Ocean Of Fear" is poots on the newts. 
** Two episodes end with a character farting - "Slumber Party Panic!" has a character yell "Don't squeeze me, I'll fart!" and then Jake does, and in "It Came from the Nightosphere", it's revealed that Jake has been sleeping in Finn's pocket the whole time - Jake turns over and farts, and the episode ends.
** In "Too Young," Finn mentions wanting to force-feed Lemongrab spicy serum "non-stop, 'till his butt falls out!" (He ends up violently throwing up instead, though.)
** A [[FreezeFrameBonus hidden one]] in "All Your Fault" reveals one of Lemongrab's thoughts in the infamous "brain screenshot" and possibly reveals ''why'' he prefers mild, bland foods:
---->'''Lemongrab:''' Mommy, don't make me eat more asparagus. It will be the end of me, [[PottyEmergency if you know what I mean]].
* {{Tomboy}}: Fionna, Marceline
* TomboyAndGirlyGirl: Marceline and Princess Bubblegum 
* TomeOfEldritchLore: The Enchridion, which also serves as a junction between worlds. Also the Pillownomicon from "Puhoy".
* TooDumbToLive:
** The Hotdog Knights. When given a chance at being granted two wishes, they wished for a box and to be blown up, respectively. Hotdog Princess is aware of this and it's ''why'' she sent Finn and Jake to help rescue them.
** Finn and Jake in "Heat Signature". When Marceline clearly tells them that the ghosts will suck their guts out when they (Finn and Jake) go to the their (the ghosts') house, Finn and Jake go anyway because the ghosts say they want to [[BlatantLies "throw a party in honor of [their] new vampire skills."]] Meaning that Finn and Jake trust ghosts over someone they've known longer.
** In "The Pods", Fin and Jake are given 3 magic beans, but are warned that one of them is evil. Their plan? Plant all 3 beans to see which one is evil, [[TooDumbToLive of course!]]
** Lemongrab and his clone: [[spoiler: They don't even pay attention to the fact that both of them- and their new subjects- are starving since they've grown obsessed in creating 'life' using the formula Bubblegum accidentally left behind. Thus, they would have died due to their impulsiveness and their obsession.]]
* TooLongDidntDub: Done for joke purposes in "My Two Favorite People." Lady Rainicorn tells Jake a joke in Korean. Jake finds it hilarious, but when Finn asks what it is, Jake says sheepishly that it "doesn't translate very well." According to the [[http://www.scribd.com/doc/18740459/My-Two-Favorite-People-Storyboard storyboards]] for that episode, it actually wasn't much of a joke.
--> '''Lady Rainicorn:''' I can't think of one... but remember that time we ran naked through that farmer's cabbage patch? He was so offended.\\
'''Jake:''' Let's not talk about that.
* TragicMonster: Ice King and Lemongrab definitely. The Lich may also count if his implied origin ([[spoiler: that he was a human who was directly hit by one of the bombs from the Mushroom War]]) is true.
* TrailersAlwaysLie: The preview for "Burning Low" heavily implies that Princess Bubblegum is jealous of Finn's relationship with Fire Princess. However, the truth is that she's only against their relationship because [[spoiler:kissing Fire Princess would cause her to go unstable and destroy the world.]]
* TrailersAlwaysSpoil:
** In the week before "Ricardio the Heart Guy" aired, teasers for the episode on Cartoon Network all but completely spoiled that he was evil, despite how ambiguous the first half of the episode tried to make it, and also showed the part near the ending in which [[spoiler:Ricardio had tied up Princess Bubblegum and was holding a broken bottle to her, and Jake punched him]].
** The commercial for [[spoiler:"In Your Footsteps" spoiled the fact that the bear steals the Enchiridion at the end. It did NOT, however, spoil the fact that the bear gives the Enchiridion to the Lich at the end.]]
** Averted with the long teaser for "A Glitch is a Glitch", which used clips from older episodes to essentially say "we can't show you anything from this episode because it's too crazy, so have a ''WesternAnimation/RegularShow'' clip instead."
** Bizarrely enough, Cartoon Network has recently spoiled the secret theme of a Five Short Graybles episode, "Another Five Short Graybles", by having the announcer say out loud what it is, and the secret themes are usually the entire POINT of the grayble episodes.
* TraintopBattle: Finn and the creepy conductor have one in "Mystery Train".
* TranslatorMicrobes: Jake dropped a neck-worn translator device on the bottom of the lake in "My Two Favorite People." The reason he dropped it was because it only had three output voices: Nightmare, Old Man, and Alien Nerd.
* TrappedInVillainy: In the episode "Jake vs. Me-Mow", Me-Mow forces Jake into killing Wildberry Princess with the threat of death.
* TreasureIsBiggerInFiction: Lampshaded in "Guardians of Sunshine".
-->'''Jake:''' These coins are thick!
* TreehouseOfFun: [[http://i.cartoonnetwork.com/v5cache/CARTOON/site/Images/i3/at_1280x1024_wallpaper4_2.jpg Finn and Jake's house.]] Not only is it awesome, but it's downright practical, with a generator and a telescope.
* {{Tricked Out Shoe|s}}: The funeral lady's shoe (complete with multiple blades and a ''lasso'') when it was fixed with a magic nail by Finn in "His Hero".
* TriumphantReprise: ''All Warmed Up Inside'', which is Jake's far more [[JustForPun heartwarming]] take on Finn's song at the beginning of the episode, ''All Gummed Up Inside''.
* {{Troperiffic}}
* TroublingUnchildlikeBehavior: Penny from "City of Thieves" is just a cute little girl... and... [[spoiler:SHE'S A THIEF! Also, she attempted to stab Finn.]]
* TrueCompanions: Finn and Jake, who frequently refer to one another as "brother". [[spoiler:Though that may be because Finn was adopted by Jake's parents.]]
* TrueArtIsIncomprehensible: InUniverse; the Ice King's collection of black and white photos in "Still", all of which are extreme close-ups of his penguin, Gunter.
* TrueNeutral: The unaligned ant. [[invoked]]
* [[TrueLovesKiss True Love's Hug]]: [[spoiler:In "Too Young", a "love-hug" from Finn is needed as a catalyst to mix the candy people's biomass with Princess Bubblegum's (to turn her eighteen again)... They still kiss just for the hell of it.]]
* TwoGirlsAndAGuy: Finn, Princess Bubblegum, and Marceline.
* TyrantTakesTheHelm: "Too Young".
[[/folder]]

[[folder:U-Z]]
* UltimateShowdownOfUltimateDestiny:
** InUniverse. 'Theoretical fightonomics' is taught in a worm college Finn and Jake visit. [[spoiler:Werewolf Queen]] always wins, apparently.
** Finn invokes this in "Frost & Fire" with the Flame Princess and Ice King. [[spoiler: [[DeconstructedTrope It ends up destroying the Ice Kingdom and Finn's relationship with Flame Princess]].]]
* UncannyValleyMakeUp: Tree Trunks when she tries to seduce an enemy. At the end of the episode, Finn and Jake try it, and Finn looks straight-up scary.
* UndeathAlwaysEnds: [[spoiler: The Lich was newly restored to life as a baby at the end of the season 6 premiere.]]
* UnexplainedAccent: Flambo's Bronx accent, Tree Trunks' Texan accent, and Goliad's English accent, all contrasting with the Midwestern newscaster voices all of the other characters use. Flambo can't even use the excuse of [[Creator/TomKenny his voice actor]] naturally having the accent.
* TheUnreveal: Is [[spoiler:Susan Strong]] human or [[FishPeople hyooman]]? [[spoiler:In "Beautopia", it's revealed that she's most likely human, though it's still technically ambiguous.]]
* UnsettlingGenderReveal: Finn and Lady Rainicorn thought [[spoiler:Tiffany]] was a girl.
* UnspecifiedApocalypse: The Great Mushroom war is the reason behind the formation of the Land of Ooo, but for the longest time, the end was only hinted at being some sort of war.
* UnspokenPlanGuarantee:
** Finn invokes this against the Fight King [[spoiler:not even letting Jake know about his plan to trick the Fight King into giving him his sword[=/=]SoulJar.]]
** AVERTED in the Ice King's first focus episode. Finn claims they can trick him into the cage. They successfully trick him into the cage.
* UnusualEuphemism:
** "MATHEMATICAL!" and other math-related exclamations are used often.
-->"Alphanumeric!"
-->"Rhombus!"
** Also, Princess Bubblegum says "What the cabbage?"
** "Lump" and various conjugations of such seems to be a sort of [[{{Smurfing}} all-purpose euphemism]] in Lumpy Space.
** There's also "shmowzow", "hamacow", "slamacow" "shmow", "spa-mow", "ski-dow", "wow-cow-chow"...
** A little something from "City of Thieves" with Penny: "It's ri-doo-doo-diculous!"
** [[RunningGag "Tck tck" *wink + "okay" gesture*]]
** "JJ Flip, what the zip?!"
** This.
--->'''Finn:''' I'm gonna man-handle those guys' banandles!\\
'''Jake:''' ''({{beat}})'' What?
** And this:
--->'''Princess Bubblegum:''' Being [[spoiler:thirteen]] is... BLOO-BA-LOOBIE!\\
'''Finn:''' ...Hmm?
** "Bazoobs", in one episode.
** "Donk" is used fairly frequently, in one of two ways:
-->'''Princess Bubblegum:''' That is way out of line, Peps, and you guys are donking up my research! *Begins knocking stuff off her table* Hello! Donk, donk!
-->OR
--> '''Huntress Wizard:''' What's it look like, ya donk?
** "THAT'S BIZONKERS!!" Frankly, this show is in love with this trope.
** In "Ghost Princess", the boys use every word they can to [[NeverSayDie avoid using the words "murder" and "die"]]. Pretty silly since they've mentioned death in practically every episode up to this point.
** OH MY GLOB!!!
** Honestly there's probably too many examples to list. Probably almost as many unique examples as there are episodes. Given the show's [[AfterTheEnd setting]], it can probably be justified as FutureSlang.
* UpToEleven: Marceline's bass amp goes all the way up to XII.
* VaginaDentata:
** The Lord of Evil's EldritchAbomination form as well as the dimple plant's dangerous form have mouths that seem to resemble this.
** The slime monster in "Dad's Dungeon".
* ValentinesDayEpisodes: "Incendium". The trappings of the holiday aren't present, but romance is the main theme and the fact that it was airing on "Valentine's Eve" was pointed out in advertisements.
* ValleyGirl: The denizens of Lumpy Space.
* VerbThis:
--> '''Magic Man:''' Yes, my children! You are so close to the answer!\\
'''Finn:''' Answer ''THIS!''
** There's this from "Dungeon":
---> '''Demon Cat:''' I'm going to unzip your skin and wear it like a little coat.\\
'''Finn:''' Unzip ''THIS!'' ''(armpit fart)''
** Finn is fond of this. Here's one from "Rainy Day Daydream":
--->'''Finn:''' How'd ''you'' get into my imagination land?\\
'''Bellamy Bug:''' I don't know, my young fellow! ''You'' tell ''me''. Perhaps I represent your secret desire to be civilized!\\
'''Finn:''' Represent ''THIS!'' ''(smacks bug)''
* VillainBeatingArtifact: Billy's gauntlet is needed to defeat the Lich [[spoiler:but the Lich destroys it before Finn can use it]].
* VillainEpisode: In "Thank You", the main characters are a Snow Golem (who is a creation of the Ice King) and his adopted pet, a Fire Wolf.
** While "Hitman" does involve Finn and Jake, Ice King clearly gets more focus in the episode than they do.
* VillainousRescue: The Ice King saves Finn and Jake's lives thrice in "Hitman".
* VillainOverForDinner: Invoked when Finn begins unleashing his greatest fears in an attempt to escape the dream world in "King Worm": one of his fears is being too young to hang out with Princess Bubblegum, so it manifests with her having coffee with the Lich (also one of his greatest fears).
* VileVillainSaccharineShow: The Lich is probably the best example, being a horrific, omnicidal undead monster and pretty much the only villain that isn't humorous in ''any'' way. The Fight King, Ricardio, Me-Mow, and the Freak Deer are all also a lot scarier than you would expect from a show like this.
* ViolenceReallyIsTheAnswer: This show just takes this trope and runs with it. A lot of times, Finn and Jake just solve something by beating or threatening to beat the ''crap'' out of it. It is even the [[AnAesop Aesop]] for one episode, "His Hero".
* TheVirus: The Lumps. When a Lumpy Space person bites a normal being, the normal being turns into a Lumpy Space person. It's like,... werewolf rules? Rawr-rawr-rawr.
* VisualPun: The {{Gag Censor}}s from "Wizard". They are ''logs of '''[[GettingCrapPastTheRadar wood]].'''''
* VocalEvolution: Finn's voice actor started going through puberty, and as such his voice gets much lower and crackier as the series goes on.
* VoiceOfTheLegion: Wife spoke ([[IAmAMonster and cries]]) in every voice of the [[FrankensteinsMonster parts she was made from]].
* VomitIndiscretionShot:
** There's one in "The Enchiridion!", "Go With Me", "The Monster", and "Another Way".
** Lemongrab in "Too Young," Jake in "Storytelling," Jake in "Jake the Dog," and Seed-Wad in "All Your Fault."
* WalkingShirtlessScene: Billy.
* TheWallsAreClosingIn: Happens with the first room Ice King, N.E.P.T.R., Tree Trunks, Shelby and Lemongrab find themselves trapped in in "Mystery Dungeon".
* WarElephants: There's an [[NinjaPirateZombieRobot Ancient Psychic Tandem War Elephant]].
* WastefulWishing:
** Jake in "The Limit":
-->'''Jake:''' It's hard to think on an empty stomach... I wish I wasn't so hungry. ''(sub sandwich appears and Jake takes a tiny bite)''\\
'''Finn:''' You wasted your wish, man!
** Jake almost does this ''again'' in "Jake the Dog," ''again'' over a sandwich. Fortunately the [[BenevolentGenie genie was fairly benevolent]] (to him, at least) and put a stop to it, basically telling him what wish he needed to save both [[WithGreatPowerComesGreatInsanity Finn]] and the pre-wish multiverse.
* WatchingTheSunset: Ice King and NEPTR (in Ice King's mind) at the end of "What Is Life?"
* WeAreAsMayflies: Inverted. It's heavily implied that Jake ages in dog years and will reach old age while Finn's barely into adulthood.
* WeWantOurJerkBack: Donny has to go back to being a jerk so he can repel the whywolves with obnoxygen, thus saving the house people. Oddly, no one directly involved wants him back. The house people, whom he inadvertently protects, don't like him, and the whywolves seem very enthusiastic to hunt the house people to extinction even knowing that they'll die afterwards.
-->'''Whywolf:''' ...until we, in turn, are devoured by the Cosmic Owl. Such is the nature of things. But! It'll be a pretty sweet ride up until that point.
* WeWillMeetAgain: The Ice King in the pilot has an oddly verbose example.
--> '''Ice King:''' Foul, noisome whelp! You've not seen the last of ''my'' wintery fangs! I'll cleave the warmth from your bones, and stop stiff your beating heart with my claws!
* WeakenedByTheLight: The Lubglubs' weakness.
* WeddingDay: The Ice King has one to a suitor who appears to willingly love him. [[spoiler:He actually {{brainwashed}} her with his engagement ring.]]
* WhamEpisode: Has its own [[WhamEpisode/AdventureTime page]].
* WhamLine:
** ''"The Ice Wizard is a weak fool..."''--Said by Princess Bubblegum, and is the first evidence of [[spoiler:her mind-control under the Lich.]] Complete with creepy background music!
** [[spoiler:"Well, ''I've'' been waiting for '''six months!'''"]] ("No One Can Hear You")
** [[spoiler:"Hello. My name is Simon Petrikov."]] ("Holly Jolly Secrets")
** "Dude... [[spoiler:I think I have a crush."]] ("Incendium")
*** Also from that episode:
---->'''Flame King:''' Any prince who is ruthless enough to kill his own bafoon would make an excellent boyfriend... '''''for my evil daughter!'''''
** "I understand now... [[spoiler:You're a ''[[MakingASplash water]]'' [[MakingASplash elemental]].]]" ("Hot to the Touch")
** At the very end of "In Your Footsteps":
--->[[spoiler:'''The Lich:''' [upon gaining the Enchiridion] Yes! One step closer.]]
** After Jake tells PB off in "Burning Low":
--->'''Princess Bubblegum:''' [[spoiler:This isn't about some petty love triangle!! Flame Princess is PHYSICALLY UNSTABLE!!]]
** The very end of "Lady and Peebles":
--->[[spoiler: Lady: I am pregnant!]]
** "I Remember You" has an entire Wham Song. It has a Wham Line, too:
---->'''Marceline:''' You don't remember anything, ''do'' you... [[spoiler:SIMON]]?
** "The Lich":
*** The end of has an utter doozy.
--->'''[[spoiler: [[AlternateUniverse AU]]!]]Finn:''' [[spoiler:Coming Mom!]]
*** Before that Princess Bubblegum dropped a huge bombshell:
---->'''Princess Bubblegum:''' [[spoiler: Finn, stop! That's not Billy. ''It's the Lich!'']]
** From "Simon and Marcy":
--->'''Marcy:''' I love you, Simon.\\
'''Simon:''' I love you, too... [[spoiler:'''Gunter.''']]
** From "The Vault":
--->'''Finn:''' [[spoiler: It's me, Shoko.]]
** From "Billy's Bucket List":
--->'''Billy:''' [[spoiler:Your father, Finn. He's alive...]]
* WhatDidIDoLastNight: In "Return to the Nightosphere", Finn and Jake wake up in a cage in a pile of bananas, and this is pretty much Finn's reaction.
-->'''Finn:''' What did we do last night?\\
'''Jake:''' Mayhaps we drank [[FantasticDrug juice of the elder toad]]?
* {{Whatever}}: Lumpy Space Princess says this ''a lot''. Even her password for getting into Lumpy Space is [[foldercontrol]]

[[folder: Whatevers 2009 ]]
.
* WhatHappenedToTheMouse: From "Candy Streets", Pete Sassafras is still locked up in Candy Kingdom jail, even though he was totally innocent.
* WhatKindOfLamePowerIsHeartAnyway: The cat in "Dungeon" has the power to be ''almost'' right about everything. It's a ShoutOut to the classic D&D monster, the Displacer Beast. Except this is a [[IncrediblyLamePun "Displaced Beast"]] ''GROAN''.
* WhatTheHellHero[=/=]HannibalLecture: In "What Have You Done?", the Ice King actually convinces Finn that he's doing the wrong thing by imprisoning him for seemingly no reason.
* WhatYouAreInTheDark: Parodied. After becoming king of a small nation, Finn learns that he is not allowed to chew his own food, among other things.
-->'''Finn:''' Oh, come on, give me this.
-->'''Servant:''' I would know, my liege.
* WhipPan:
** Near the beginning of "Susan Strong".
** There are a lot of these in "Daddy's Little Monster".
* WhiteAndGreyMorality: Overall, the story tends to vary between this, BlackAndWhiteMorality, and the occasional WhiteAndWhiteMorality Conflict or MoralityKitchenSink scenario. Hell, one time EvilVersusEvil was thrown in [[PlayedForLaughs for laughs]]:
--->'''Finn:''' I love zanoits! They're the best!\\
'''Princess Bubblegum:''' Zanoits kill hundreds of thousands of plantoids a year.\\
'''Finn:''' Oh, no, not the plantoids!\\
'''Princess Bubblegum:''' Plantoids produce mellotoxin.\\
'''Finn:''' ''(beat)''\\
'''Princess Bubblegum:''' MELLOTOXIN ''KILLS'' ZANOITS!
* WhyDidItHaveToBeSnakes: Finn has a specific fear of the ocean.
* WidelySpacedJailBars: In "Up a Tree," Finn is imprisoned in a jail cell with these. [[LampshadeHanging He indeed ends up just walking out.]]
* WidgetSeries: Korean, technically.
* WilliamTelling:
** Fiona is doing this in the Fiona & Cake story Marceline tells in "Bad Little Boy"; using a throwing axe to cut an apple balanced on BMO's head in half.
** In "Holly Jolly Secrets", the Ice King attempts to use his ice powers to shoot an apple off Gunther's head and ends up encasing Gunther's head in ice.
* WitchSpecies: Played straight or GenderFlipped, as WordOfGod gives "Wizard" as the species for [[BastardBoyfriend Ash]] and [[AnIcePerson the Ice King]] (though the latter [[spoiler:was born human]]). We also see "witches," but it's unclear if they and Wizards are the same species, two examples of this trope or what.
* WithGreatPowerComesGreatInsanity:
** In "Crystals Have Power" this happens to [[spoiler:Tree Trunks.]]
** A big one for [[spoiler: the Ice King]], as revealed in "Holly Jolly Secrets". Turns out, [[spoiler: he was just a regular guy that found the crown, gaining his ice powers, but losing his sanity from the crown's visions]].
** Happens to Finn twice: in "The Real You" when magic glasses make him omniscient, and in "Finn the Human"/"Jake the Dog" when [[spoiler:he puts on the Ice King's crown]].
* WizardBeard: Exaggerated with the [[http://www.flickr.com/photos/84568447@N00/6106037147/in/photostream/ Grand Master Wizard's]] beard. Now THAT'S a {{wizard beard}}!
* WizardDuel: The episode [[ExactlyWhatItSaysOnTheTin "Wizard Battle"]].
* WombLevel: [[spoiler:Ricardio]]'s evil lair in "Lady and Peebles". Possibly made from [[spoiler:biomass he harvested from the Ice King]].
* WordSaladHumor: All the time.
-->'''Finn:''' This stinkups mega bamm-bamm to the J-stop.
** The speech at the end of "The Other Tarts" seems to be complete nonsense:
--->'''Royal Tart Toter:''' This cosmic dance of bursting decadence and withheld permissions twists all our arms collectively, but if sweetness can win—and it can—then I'll still be here tomorrow to high-five you yesterday, my friend. Peace.
** Anything Cuber says. Ever.
* TheWorfEffect: In "Blade of Grass", Finn is CursedWithAwesome by obtaining a cursed sword that, like [[StuckItems cursed weapons from RPGs]], cannot be un-equipped. Its magic appears to also give some sort of RPG-like "dexterity stat bonus" that makes Finn far, far more awesome at using it than he would otherwise be, showing him carving a picture of his face into objects with a flick of the wrist. In ''the very next episode'' "Rattleballs" however, to emphasize how much better a swordsman Rattleballs is than Finn, this effect seems to completely disappear, to the point that not only does Finn not stand a chance against him in a swordfight, but finds it challenging simply to deflect eggs thrown at him in a training excercise.
* WorldInTheSky: Lumpy Space. Also, the Cloud Kingdom because it has [[BubblyClouds solid clouds that you can walk on]].
* WorldOfBadass
* WorldOfChaos: The Nightosphere is literally sustained by ChaoticEvil, while the Crystal Dimension and Lumpy Space at least skirt this trope. And heck, Ooo isn't exactly normal either.
* WorldOfHam: There are many hams in this world.
* WorthyOpponent: Jake and Finn enjoy fighting "Science Cat and Shark" fore sheer recreation in ''My Two Favorite People.''
--> '''Jake:''' Who are these guys?! This is a great fight!
* WretchedHive: The city of thieves. [[PlanetOfHats Every single inhabitant is a thief]], and if you go in there, [[FisherKingdom you become a thief too]].
* WriterOnBoard: Jake's whole conflict with eating Meat Man in "Hitman" could be interpreted as a message to the viewer that they should question eating meat. One of the episode's storyboarders was Jesse Moynihan, who is a vegetarian.
* XMeetsY:
** ''TabletopGame/DungeonsAndDragons'' on hallucinogenic drugs, or ''The Neverending Story'' as created by the people behind ''WesternAnimation/SpongeBobSquarePants.'' (both shows have TomKenny in the cast, so it counts)
** ''ABoyAndHisDog'' meets ''VideoGame/TheLegendOfZelda''.
** ''TabletopGame/DungeonsAndDragons'' meets ''WebComic/AxeCop''.
** ''VideoGame/{{Fallout}}'' on salvia and ecstacy.
** ''TabletopGame/CandyLand'' meets ''Franchise/SuperMarioBros''
* {{Yandere}}:
** Tree Trunks in the crystal world.
** Finn doesn't like [[http://www.youtube.com/watch?v=IvisiyE7dPo anyone else]] being Jake's best friend.
** Flame Princess mixes this with a healthy dose of {{tsundere}} and a frosting of ''evil''.
* YankTheDogsChain:
** Ice King at the end of "The Eyes:"
--> '''Ice King:''' I'm... still not happy.
** [[spoiler:Also Princess Bubblegum being aged back to 18 in "Too Young," right when it seemed that her and Finn would finally become more than friends.]]
** Her pushing Finn further away in "Incendium".
** Just when Finn starts to finally quell Flame Princess's emotions for good so that they can be together, she realizes that [[spoiler:Finn secretes water through tears when they hug, so they can't be a couple.]] That is until a later episode, but there are still obstacles.
* YearInsideHourOutside: In ''Puhoy'' [[spoiler: this happens to Finn. He goes to a pillow world, grows up, gets married, and has children. After he dies, he wakes up again in his own world a few minutes after he left, and begins to tell Jake about [[AllJustADream a crazy dream he had]]. A phone call interrupts him, and Finn totally forgets even having a dream...if that's what it was in the first place.]]
* YouAllMeetInACell: The episodes "Return to the Nightosphere" and "Mystery Dungeon" both begin this way. In the first it's Finn and Jake waking up in a cage in the Nightosphere. In the second, it's Ice King and several minor characters in a dungeon.
* YouCantFightFate: Jake has this mentality in "The New Frontier".
** In every alternate universe shown so far, [[AnArmAndALeg some event happens that makes Finn lose an arm]]. [[spoiler:As of "Escape From the Citadel", Main!Finn lost his as well]].
* YouExclamation: Delivered to Finn by Flame Princess in "Incendium".
* YouMonster: Said by Jake to Princess Bubblegum when she tries to get Finn away from Flame Princess.
* YouNeedToGetLaid: Ice King, but not for lack of trying. It might be one of the reasons why he's [[NerdsAreVirgins a big nerd]]. WordOfGod admits it being true.
* YouNoTakeCandle:
** The businessmen's weird grammar in "Business Time."
-->"We love work for you!"
** Susan Strong's English in general.
--->"Finn...help Susan!"
* YourCheatingHeart:
** Parodied in "The Monster" when Lumpy Space Princess thinks that a wolf is cheating on another wolf with yet another wolf.
-->'''Lumpy Space Princess:''' TONY!! JESSICA'S CHEATING ON YOU!!
** Again parodied in "A Glitch Is a Glitch" when Jake's right arm asks PB's hand if she's cheating on him (because PB was making out with her hand). It... ''almost'' makes sense in context.
** Finn cheats on Flame Princess with Roselinen in "Puhoy." Justified as he couldn't escape the pillow world. (Though he did have a cellphone handy...)
* YoureInsane: Princess Bubblegum says a variation of this at {{the climax}} of "The Real You".
-->'''Princess Bubblegum:''' Finn...you've gone ''insane!''
* YourMindMakesItReal: Jake has a ''very'' powerful imagination.
** [[spoiler: Finn]] in ''The Tower'' creates a psychic arm that is fueled by his desire to get revenge on his dad and replace his lost arm
* YourMom:
** The Marauders to Marceline's dad in one episode:
-->'''Marceline's dad:''' What wears a dark suit, is completely evil, and is about to suck out all your souls?\\
'''Marauder:''' Your mama.\\
'''Marceline's dad:''' ({{beat}}) [[InsultBackfire That's right. I'm your mama.]]
** From "Hug Wolf":
--->'''Jake:''' Finn...say something to reassure me.\\
'''Finn:''' I'LL HUG YOUR MOM!
* YourTomcatIsPregnant:
** Gunter lays an egg in one episode. The characters even lampshade it. That said, the exact details are fairly ambiguous. After all, a magic cat creature hatched from the egg.
** Also: The Ice King apparently lacks the capacity to differentiate between one penguin and the next, so they're ''all'' Gunter, further complicating the issue. When attempting to determine the gender of this particular Gunter, he tries looking at the penguin's general crotchular area, which doesn't do him much good (look up "cloaca" sometime).
%%* YourSoulIsMine: Zero context, please add context before unhiding.
