Shout Out / Adventure Time

Shout Outs in Adventure Time.

---

• In the original short Finn mentally projects himself to Mars.
• The position Jake assumes at the end of the opening and this picture◊ is reminiscent of this picture◊ in Conan the Barbarian. Finn doesn't mimic Conan's position though.
• One promo after "Freak City" has the double rainbow video recreated with Jake witnessing two Rainicorns.
• Marceline calls Finn a Castle Crasher in her second episode.
• In "The Duke", there are multiple ones.
  • One of the potions Finn and Jake are messing around with is labeled "Caturday Surprise."
  • In the fake ambush that Finn and Jake set up, they do the infamous flying kick exchange between Kenshiro and Shin from Fist of the North Star.
  • A squirrel is reading a holographic newspaper where there's an advice column by Jake. Next to it, there's an excerpt from the classic 19th century book Advice to Young Men by William Cobbett.
• Billy's sword is called Nothung, the name of Siegfried's sword in Der Ring des Nibelungen.
• The title card of "His Hero" is a nod to Frank Frazetta's Death Dealer.
• Finn's plastic surgery turns Lumpy Space Princess into a Gizmoduck lookalike.
• After being freed from prison in "What Have You Done?", the Ice King loudly proclaims "CAST DETECT SECRET DOORS!" before blasting a hole to freedom. Mind you, that happens in a room that has been proven to have at least two real hidden doors.
• The horse in "The Eyes" is based on the Fat Shetland Pony from Hark! A Vagrant.
• The Ice King is shown in one episode to have a "Ring, Ring, Ring, Ring, banana phone"
• The series title card◊ is styled after the Dungeons & Dragons 3rd Edition logo◊ and the cover art◊ of the game Another World. However, the animation of the title card seems to be based off of the title screen of The Legend of Zelda: A Link to the Past, complete with the flash that occurs when the sword is inserted into the title words.
• The episode "Guardians of the Sunshine" is FULL of references to video games.
  • It uses sound effects from many games, particulary Mega Man (Classic).
  • It also makes a few Super Mario Bros. references, like level-1, and the Bomba (Bob-omb).
  • Finn's face turns into Pong at one point.
• In "Power Animal," Finn busting out of his restraints is a reference to Total Recall (1990).
• One of the zombie Candy People in "Slumber Party Panic" tells Princess Bubblegum to "Gimme some sugar, baby."
• The episode "Dungeon" featured a number of DnD monsters, such as the mimic, the trapper (pretends to be the floor), and a gelatinous cube.
  • And "Wizard Battle" has a brief cameo◊ by a classic Carrion Crawler◊.
• In "My Two Favorite People", Finn, Jake, and Lady Rainicorn encounter a wizard who is handing out power rings. Finn also wears 10 rings his hands with each one displaying a different power, just like the Iron Man villain The Mandarin.
• According to Natasha Allegri's Formspring, Fionna and Cake are based on a certain planet-themed magical warrior girl and her talking black cat. The rabbit hat is a dead giveaway.
  • The dress Fionna wears in the episode◊ is another Shout-Out to Sailor Moon.
  • Fionna's sword in "The Prince Who Wanted Everything" appears to be Sailor Moon themed, with its bow and ribbons.
• The robot orb-looking things that Fionna slashes at in "Adventure Time with Fionna and Cake" were based on the farm-intruding enemies from The Legend of Zelda: Majora's Mask.
• "Mortal Recoil" contains a bunch of clear references to The Exorcist and The Grudge.
  • Also from "Mortal Recoil", the view through the Ice King's "wizard eyes" could be a reference to H. P. Lovecraft's short story "From Beyond".
• The tagline for the movie "Heat Signature" is "Under the ocean, no one can hear you die". This is a reference to the tagline for the movie Alien (1979): "In space, no one can hear you scream."
• "Morituri Te Salutamus":
  • Just before one of the fighters dies, he says something along the lines of, "Et tu, Verus?" which is a reference to Julius Caesar.
  • Finn introduces Jake by saying "Yes, this is Dog".
• The "Susan Strong" title card is a reference to Lost. There was also a "Lost pan" in the storyboard that got cut from the episode.
  • Not to mention how Susan Strong & Co also lived underneath a Hatch...
  • One of the fish people is wearing what looks like a Pedo Bear costume.
• The title card for The Enchiridion! was inspired by a ''Science Fiction'' magazine cover.
  • The word "enchiridion" itself means "manual" - it was the title of the first ever self-help book, as well as of several later advice books on how to be a good person or a good knight.
• Ash erasing Marceline's memory of her breaking up with him was slightly inspired by Eternal Sunshine of the Spotless Mind.
  • The entire memory sequence is a reference to Being John Malkovich, what with the shifting gravity, various doors through memories, and the nature of being inside someone's head.
  • It can also be seen as a refrence to Inception with the extraction of an idea from a dream.
  • Jake's Giant Foot of Stomping is, of course, a reference to Monty Python's Flying Circus.
• The Lich King is a horned, ridiculously scary, skull-faced monarch who can raise skeletons and whose power lies in a pit of green ooze. Compare to The Horned King, a horned, ridiculously scary, skull-faced monarch who can raise skeletons and whose power lies in a pit of green ooze.
• The game Dropball, played by Ghost Man in "Blood Under The Skin," is a Shout-Out to Bullet Ball, the high calibre tablegame designed for the 21st-century lifestyle that went memetic after creator Marc Griffin's memetically depressing/hilarious appearance on American Inventor. Ghost Man's voice sounds quite a bit like Marc Griffin's and several of his lines are quotes from the American Inventor episode.
• Finn's method of curing the zombies in "From Bad to Worse" is to douse himself with the antidote and walk into a mob of them so they all touch him.
• The title card for Beautopia◊ references the famous Greetings From Asbury Park, N.J. postcard◊.
• The episode "No One Can Hear You", references Alien when the candy people are shown to be stuck to the walls of the sewer with a goo, like the Xenomorphs do their victims. Even the title is borrowed from the tagline of the movie: "In space, no one can hear you scream." Finn and Jake are screaming in the title card.
  • On the opposite end of the spectrum, Finn's casts breaking is really similar to Forrest Gump's leg braces.
• The crew made an episode in honor of a little kid and his drawing of her original character, Me-mow, fighting Jake, which he titled "Jake vs. Me-mow".◊ Appropriately, the episode is called "Jake vs. Me-mow".
  • The music box Finn uses to accompany the lullaby is strongly similar to the Orb of Isis in The Simpsons episode "Lost Our Lisa."
• The Bucket Knight from "Dungeon" is a shout-out to the Alternian Imperial Drones from Homestuck. The artists are confirmed to be fans: a picture of their whiteboard shows doodles of the main characters.
  • In the episode "Apple Wedding", one of the gingerbread men looks very similar to DD or Jack Noir.
• From "Paper Pete" we have: "YISS!!"
• In "Dad's Dungeon", one of the Fruit Witches tries to convince Finn to "Partake of the fruit..."
• The first issue of the comic shows a cross-section of the ground... including a fossilized T. rex about to stomp on a house.
  • Well, seeing as the comic itself was written by Ryan North...
• The episode "Wizard Battle", the Grand Wizard states that wizards will fight using the eight schools of magic. This is likely a reference to Dungeons & Dragons' eight schools of magic.
  • In the same episode, the Wizard Abracadaniel shouts "Cantrip!" upon casting. In D&D, a cantrip is a minor spell typically only useful as a distraction in combat (incidentally, exactly the kind of magic Abracadaniel uses.)
• In "Dad's Dungeon", Finn and Jake come up to a fork in the passage. One path has magical flowers. The other has a giant monster that says "None shall pass!"
• "Hot to the Touch" has a double mecha anime reference when Finn and Jake are flying to stop Flame Princess's rampage:
  Jake: I feel like I could touch the heavens... and sock angels!
• In "Five Short Graybles" has Princess Bubblegum making a familiar toothy smile while enthusiastically saying "CHEEEESE".
• In "Dream of Love", during the movie night, we see a guy saying "Look at this cup. Now look at this cup!"
  • And an elephant hooks up with a pig.
• "Princess Monster Wife" alludes to Perseus and Medusa when Finn and Jake use mirrors in order not to gaze upon the titular monster's hideousness directly, though they are only in danger of fainting instead of being turned into stone.
  • While trying to reassure Monster Princess that she's normal, Ice King refers to her as his "beautiful princess bride."
• The episode "Goliad" and its eponymous character are named after Goliad, Texas. While the place figures in Texas history, there's no intended deeper meaning in the show; the episode's writer just thought "Goliad" sounded cool. Goliad's and Stormo's third eyes that erupt from their foreheads when they use their psychic powers is a reference to the main antagonist's pineal gland stalk in the film From Beyond.
• "Beyond This Earthly Realm":
  • Jake sounds like a Wookiee when he yawns.
  • Ice King says that Finn "can't touch this!"
• The Card Wars game is a homage to Magic: The Gathering. After doing great with no prior experience playing, Finn calls himself a "Card Wars Super Amadeus".
• The internet game "Rhythm Heroes" is clearly a parody of Rhythm Heaven.
• In "Wizard", Finn proclaims that he wants ALL THE STAR BADGES and strikes a pose similar to the "All the Things!" meme made famous by Hyperbole and a Half.
• Earl of Lemongrab is an allusion to Mary Shelley's novel "Frankenstein." Like Frankenstein's Monster, he is a science experiment gone wrong who is rejected by his creator and forced to live in isolation. Lemongrab is also an allusion to Lovecraft's 'Herbert West: Re-Animator,' in which a mad scientist brings to life corpses, which become screaming, unintelligent psychos after he injects them with chemicals.
  • His name is a pun on Lemon Drop candy.
• In "Sons of Mars", Abraham Lincoln gives Jake (as Magic Man) two choices of execution. The first is total annihilation, the second is convert his body to living stardust. During the second description, his heads floats amidst color bars that looks like "Jupiter and Beyond the Infinite" in 2001: A Space Odyssey.
• In "King Worm", Finn is trapped in a room full of his fears (being in water).
  • A very likely shout-out given the mid-episode reveal of All Just a Dream and accompanying Unreveal.
• In "Lady & Peebles", Ricardio closely resembles Majora's Incarnation. That part of the episode's storyboarder, Rebecca Sugar, is known to be a Zelda fan.
  • Also from that episode, PB gives Ice King a new heart partially made of maracas, which he then shakes while speaking vaguely Spanish phrases. This is possibly a reference to Charo, a Spanish-American actress probably best known for appearing on The Love Boat and "shaking her maracas".
  • The design of the Black-Ice Cave itself was inspired by Eternal Darkness and Amnesia: The Dark Descent.
  • PB's Heart Signal Tracker is reminiscent of the Motion Tracker from Aliens
• The entirety of the final conversation in "Ignition Point" references Dungeons & Dragons (specifically the Character Alignment aspects) multiple times.
  • It also (rather blatantly) references Hamlet with the acting troupe and Jake coming up with the plan from the play by himself to find those who plan to kill the Fire King. A portion of Hamlet's "To be or not to be" Soliquly is heard earlier as well, and it turns out that the Flame King played the Cladius, with the two plotting against him being would-be Hamlets, the Flame King's nephews whose father the Flame King killed to take the throne. This is common knowledge, and no one minds because everyone in the Flame Kingdom is evil.
  • In the scene with the fire snake, Jake uses its hissing to say "Ssssuffering ssssuccotash"
• In "The Hard Easy", the Mega-Frog turning back into Prince Huge is oddly reminiscent of the transformation sequences from Sailor Moon.
  • The predicament of Prince Huge in itself is already a homage to the fairy tale The Princess And The Frog.
• In "Reign of Gunters", Gunter's pink kitten is revealed to have telekinetic and energy powers, which is reminiscent of Mew.
• The book 'Mind Games' and its author Jay T. Dawgzone seem to be a shout out to The Mystery Method and its originator, Mystery.
• In "I Remember You", Jake imitates Diedrich Bader's Batman.
• The leader of the Destiny Gang in "Finn the Human" looks an awful lot like Kamina.
  • Speaking of anime, let's play a drinking game. Drink for every Fullmetal Alchemist reference. So, let's see. Two blond brothers, the older one has a mechanical arm; the mechanical arm can become a sword; the family household bursts into flames; untold power coming from red stones at the cost of thousands of lives; the forceful creation of alternate universes in which one is based in a rural farmtown...
  • The Destiny Gang's eclectic getups are supposed to be reminscent of Fist of the North Star.
  • Trommy looks like Prince Zuko.
  • The domino mask-wearing Destiny Gang member looks suspiciously like Groose.
  • Prismo explicitly makes a reference to "The Monkey's Paw" when he's explaining to Jake how his wishes work.
  • And Jake initially wants to wish for a sandwich, which was also Homer's attempt at a foolproof wish in the Treehouse of Horror parody of The Monkey's Paw.
• In "Holly Jolly Secrets", Ice King creates snow goons to attack Finn and Jake.
• Finn playing with the mini-people in "All the Little People" is very reminiscent of The Sims, the minis even speak in gibberish.
  • Or on a creepier note, his utter ruination of their lives and the off-kilter, creepy "Playing God" vibe of the episode seem a bit reminiscent of a certain animation for Mark Twain's "The Mysterious Stranger".
    • Princess Bubblegum experimenting on some blob "people" by snipping off their limbs in "The Lich" could also be a reference to "Mysterious Stranger".
• Marceline riding the Rock Giant's finger to the music shop nearly resembles the opening sequence of Superjail!.
• In Adventure Time: Hey Ice King! Why'd you steal our garbage?!! if you try to enter the first dungeon before finding Finn's sword, Jake tells Finn that "It's dangerous to go alone." a famous line from the original The Legend of Zelda.
  • In the third dungeon, the Ice King says "But enough talk! Have at you!" before you go to fight the boss; examining the third Garbage Princess will prompt Jake to call it "a miserable little pile of garbage." Fittingly, the boss of the dungeon is Marceline.
  • The secret final boss battle with Lumpy Space Princess is a direct homage to Kirby's fight with Nightmare.
  • Jake residing in Finn's backpack is highly reminiscent of Banjo-Kazooie.
• "Mystery Dungeon" is partly a reference to Cube.
  • In the same episode, Tree Trunks cutting her way out of a monster while saying "I'm born again!"
  • The animated book is reminiscent of Mickey Mouse.
  • "Everything is true in the garden of your mind."
• "Up A Tree" has the occupants of the tree doing an I Am Legion chant that sounds very familiar: In the tree, part of the tree. In the tree, part of the tree.
• In "All Your Fault", the bizarre creatures in the Lemongrabs' kingdom which the Lemongrabs made they made from their entire food supply look like the creatures in Hieronymus Bosch's "The Garden of Earthly Delights"◊.
  • One of the creatures, Lemon John, has a crisis: if he attacks the Candy Kingdom the Lemon people will live but the Candy people will be destroyed; if he doesn't the Candy people will live but his "family" will die. Lemon John states this in a way that sounds like Jean Valjean's "If I speak I am condemned/If I stay silent I am damned". Lemon John takes a third option: he saves everyone by reverting back a ton of lemon candy.
  • It is possible the Lemonjohn's design was inspired by the colossi from Shadow of the Colossus.
• In "The Great Bird Man" Xergiok is reminiscent of Oedipus - he's a former king who's blind, lame and a recluse after committing great wrongs and his beard is "adorned with eyeballs", only this time they're whole.
  • Xergiok's eyes may also be a reference to Homestuck. They match (Homestuck spoilers) Sollux's after Eridan blinds him, and he explains their loss as, "I miffed off a wizard and he took my eyes."
• "Simon and Marcy" has Simon singing the opening theme song of Cheers. "Filmed before a live studio audience. Norm!"
• Choose Goose? More than likely a subtle shout out to the Goo-Goose that chews goo in Dr. Seuss' children's tale Fox in Socks.
• In "Death in Bloom", Morrow get Bubblegum like the Bird to get Link to teleport in another place in The Legend of Zelda: A Link to the Past
• "Puhoy":
  • Finn comments that Jake's pillow fort is "Smaller on the outside", which are the words used in the Doctor Who Christmas Special "The Snowmen" by current companion Clara Oswin Oswald.
  • When Rosalinen realizes Finn must return home, she is accepting of his decision and only asks that he remember her - the same request Marin makes of Link when she realizes he must leave by waking up, which will destroy her and the rest of Koholint Island in The Legend of Zelda: Link's Awakening.
  • The plot of the episode appears to draw from the Star Trek: The Next Generation episode "The Inner Light," in which Picard similarly lives out a familial life in a dream; in addition, adult Finn is voiced by Jonathan Frakes.
• It is possible that that the name of "BMO Lost" is a reference to Paradise Lost.
• In "A Glitch Is a Glitch", Ice King unleashes a computer virus that affects people in real life.
  • It might be a coincidence, but the title of the episode is similar the N.W.A. song "A Bitch Iz A Bitch".
• As well as classic 70s kung fu movie references, "The Chamber of Frozen Blades" was basically one big Naruto reference. Perhaps most blatantly, the promotional art◊ shows Rebecca Sugar (one of the writers/storyboarders) wearing a Konoha hitae-ate.
• Scorcher the unstoppable fire-wielding assassin from "Hitman" basically is Sabrac the, um, unstoppable fire-wielding assassin from Shakugan no Shana.
• In "Apple Thief" the gang get caught by some gangsters who try to "feed them to the pig". Mr. Pig mentions his former career as a criminal-eater again when he reappears in "Dream of Love".
• In "The Suitor", Pebs mentions a key to the shadow realm.
• In "Another Five More Short Graybles", Lemongrab shouts "ONLY ONE!" as he eats his brother.
• "James Baxter the Horse" is a homage to a Disney and DreamWorks Animation animator of the same name. Finn looks up to the fictional James Baxter like how Pendleton Ward looks up to the real James Baxter - who animated and voiced his namesake.
• Wizards Only, Fools:
  • When Finn, Jake, and PB enter Wizard City, it looks like Diagon Alley.
  • The underwear thrown on Finn in prison might be a shout-out to the less child-friendly assault on Clarice in The Silence of the Lambs.
    • That episode is also as close as you can get to a Superjail! episode.
• In "Be More" when BMO goes to get fixed, he notes their personalities and memories are erased and he doesn't want them to disappear like tears in the ''oven''.
• Not really a shout-out, but "Björk" is used as an exclamation thrice in "Jake Suit".
• One of the stickers Cinnamon Bun uses for his note in "Earth and Water" looks like one of the smaller creatures from My Neighbor Totoro.
  • In the same episode, after Flame Princess has deposed her father, she's wearing an outfits and hairdo that looks a lot like Azula. From Fire Princess to Fire Princess.
• "The Vault":
  • The Regression sim game looks a lot like Super Hexagon
  • In the same episode, the Bath Boy Gang Leader hold an uncanny resemblance in mannerisms, body shape, and voice to King Herod from Jesus Christ Superstar.
• The premise of "Train Dungeon" is Finn and Jake facing off against a bunch of other people who have gone insane/corrupted from wandering the train (or maybe world in this case) for dozens of years and killing those who are also lost on the train. Sound familiar?
  • Finn has an Ioun Stone orbiting his head
• In "Memories of Boom Boom Mountain", the Head Marauder calls Finn a "chicken" as he walks out of the village to see who is crying. Finn slowly turns around with a Death Glare on his face and asks: "What did you call me?" This scene is VERY reminiscent of Marty McFly's reaction to being called the same thing in the Back to the Future trilogy. The fact that the Head Marauder is voiced by Thomas F. Wilson (aka. Biff Tannen) certainly helps.
• In "Too Old", the original Lemongrab's appearance as a bloated Caligula figure that moves around by floating is very reminiscent of Baron Harkonnen.
• Clarence and Ghost Princess' story is basically that of Achilles and Penthesilea.
• In "The Suitor", a helmet that looks oddly like Jango Fett's can be seen on a bookshelf in Braco's room.
• In "Marceline's Closet", you can see the Pale Man's head and one of his hands among the hunting trophies mounted on the wall (directly above the titular closet)
• In BMO Noire, BMO and Neptr have an exchange highly reminiscent of the famous exchange between Rei Ayanami & Kaworu Nagisa in episode 24 of Neon Genesis Evangelion.
• In "City of Thieves", the section when Finn believes himself to have been darkened by the city is a spot-on parody of Batman: The Animated Series.
• In "Betty", During the fight against Bella Noche, a character named James (as in Jesse James) Longman, wearing a pink shirt, uses heavily slang-ridden speech, and shows a formula he made in his lab, which is not ideal. In other words, he's a Shout-Out to Jesse Pinkman.
• In "The Red Throne", the fight scene between Flame King and Don John the Flame Lord is a near-exact replication of the memetically infamous fight scene from They Live! (To top it off, both characters are even voiced by Keith David and "Rowdy" Roddy Piper, respectively)
• One of Johnny's records in "Bad Timing" (specifically the one LSP uses for a gag) is the Frank Zappa album "Apostrophe."◊
• The Grass Sword grows into a giant, monstrous, twisted arm in the style of Tetsuo when Finn tries to prevent his father from escaping.
• Princess Bubblegum wears Dr. Sattler's outfit in James II.
• The Fleshing out of the Lich due to the Crystal Guards blood is somewhat reminiscent to Eri Masami's demise in Serial Experiments Lain.
  • Also the Headless Horseman in Sleepy Hollow (1999) (which is probably a shout-out too given how much it's influenced by Hammer Horror movies).
• The origin of the Gumball Guard in "Rattleballs" is a shout out to the Manhunters from the Green Lantern mythos. They even have the same color scheme as the Manhunters.
• Finn's tower from "The Tower" looks like it's made out of Minecraft blocks.
• In "Furniture and Meat," Wildberry Princess attempts to execute Finn and Jake for their abuse of the power of wealth by ironically drenching them in their molten gold, likely imitating the Karmic Death of Viserys Targaryen in the A Song of Ice and Fire / Game of Thrones franchise
• The "freaky clothes" Lumpy Space Prince dons in "The Prince Who Wanted Everything" are portions of the outfit of Char Aznable of Mobile Suit Gundam. They match well with his many Animesque facial expressions.
• The 5th season (2012) episode "Jake the Dog" contains an author Shout out to the Head of Story, Kent Osborne. He was in a 2010 film called Uncle Kent, and the dialogue that Prismo and Jake share in the jacuzzi is verbatim that which Kent and Joe have in the swimming pool (the lines about co-ordinating breakfast and views on relationships)
• During "We Fixed A Truck", BMO briefly shows the famous "Flying Toasters" screensaver from After Dark on its screen.
• The season 6 episode,"Something Big", had a shout out to Attack on Titan, of all things, with giant humanoids, a flying army attacking said giants (the majority being killed in the process), cannons firing from the Candy Kingdom's walls, with the giants regenerating their limbs and heads when destroyed. There's even a colossal giant leading them, with a weak spot near its head, to top it all off.
• "Breezy": Another Sailor Moon-esque transformation sequence.
• "Food Chain":
  • The song that Jake and Finn sing when they're first transformed is the Queen of Night's aria "Der Hölle Rache" from Mozart's The Magic Flute.
  • Caterpillar-Finn and his bride Erin fall through the air holding hands like Chihiro and Haku (or alternatively, like Renton and Eureka).
  • It's not too hard to see the influence of "Komm Süsser Tod" in the Food Chain song.
• "Little Brother":
  • Kent's archetypical Hero's Journey with High Fantasy elements through a tight, dark, brown, tubular space is reminiscent to South Park's Lemmiwinks adventures.
  • The Rat King bears more than a passing resemblance to Emperor Zuul of all things. (They even fight in an area that resembles the background of their final fight in Super Robot Wars Z.)
• "Something Big": Darren summons help during the assault on the Candy Kingdom with the incantation "I call forth the Legion of Cadmus, The Dragon's Teeth." This is a shout out to Greek Mythology, where Prince Cadmus threw dragons' teeth on the ground and had skeletal soldiers appear to fight.
• "Princess Day" is a big honking reference to Thelma & Louise, complete with the iconic ending.
• A Freeze-Frame Bonus in Joshua and Margaret Investigations: when Margaret enters the arsenal, there is a Pokeball hanging on the wall among other weapons.
• "Ghost Fly" is a major love letter to quite a few famous Horror movies, including Peppermint Butler recreating the famous The Exorcist picture standing in the fog and Finn turning into a giant fly. Not to mention many Supernatural fans will find the references to protection against vengeful spirits hilarious.
• For some reason in "Everything's Jake", all the major extra characters of the episode are voiced by Futurama voice actors using the voices of characters from the show. For instance, Jake (voiced by John Dimaggio, voice of Bender) has a best friend with the voice of Phillip J. Fry, encounters and authority figure with the voice of Zapp Branigan, receives a message from a sea-urchin-like creature with the voice of Tinny Tim, is cautioned by a scientist with The Professor's voice who leaves behind his father, who speaks in the voice Tress MacNeille uses when playing incidental juvenile boy characters (such as Guenter the monkey).
• "The Cooler": Princess Bubblegum's surveillance room looks like the one in The Dark Knight, although Lucius Fox destroyed his after just one use because its privacy-annihilating capabilities disturbed him while PB's had appeared in a lot of episodes and was only destroyed when Flame Princess called PB out after her over-the-top behavior nearly destroyed the Flame Kingdom.
• The dance that Sweet P does in "Gold Stars" looks a lot like Chunk's Truffle Shuffle from The Goonies.
• The Porp must Flow from "Dark Purple".
• "Jermaine":
  • The whoppin' big sword seen in Jermaine's house resembles Cloud's Buster Sword from Final Fantasy VII.
  • The teddy bear/cassette player refers to Teddy Ruxpin, an animatronic toy extremely popular during the mid-1980s.
• "The Visitor" is a Whole-Plot Reference to Pikmin. In both, a space traveler crash-lands in a planet (though in Martin's case, it's not exactly an alien planet) and finds a group of small creatures which help him rebuild his ship.
• The Minerva bots in "Helpers" have anaesthetic syringes emerging from their fingers, making them similar to a combination of the Autons and the Handbots from Doctor Who.
• The title of the Season 9 episode "Always BMO Closing" references the famous line "Always be closing" from Glengarry Glen Ross. In the episode, BMO and Ice King pretend to be salesmen.
  • At the end of the episode, Ice king says "The Ice Man leaveth."
• The Nightsword that Peppermint Butler gives Finn in "Marcy and Hunson" has a built-in compass, like the Red Ryder BB gun in A Christmas Story.
• The Green Knight in "seventeen" is almost entirely ripped from "Sir Gawain and the Green Knight"
• Neddy is likely based off from Nidhoggr the dragon that gnaw's on the roots of Yggdrasil.
• In "Gumbaldia" Uncle Gumbald has a painting painted that is very similar to Jacques-Louis David's Napoleon Crossing The Alps
