History MushroomSamba / WesternAnimation

** In "[[Recap/TheSimpsonsS26E21BullE Bull-E"]], Otto hallucinates twice. First, he hallucinates about hitting the "I Choo-Choo-Choose You" train with a Ringo Starr-esque voice (parodying Thomas the Tank Engine), and at the end, hallucinates about the orange Magic School Bus, driven by Ms. Drizzle (a parody of Ms. Frizzle).

* In the ''WesternAnimation/AmericanDad'' episode "The Magnificent Steven" Stan buys Steve and his friends a small herd of cattle in an attempt to toughen them up, little does he know the cows are infected with Mad Cow Disease, during the course of events he make them slaughter the calf and only he eats the meat which causes him to hallucinate that owls are out to steal his meat (we don't see this), then he takes them to an alley where he hallucinates that he is in a bright more cartoony world and sings a Western song with a jack rabbit and prairie dog. We then cut to reality and he's dancing in his underwear with a beer pack and burger wrapper, he then orders them to cross a river which is actually a busy highway, and they end up having to save him from this. In real life he would've eventually died.
** In the episode "In Country...Club" after eating a rare bird Roger hallucinates that he's flying in a brightly colored CGI world with constantly changing shapes and floating in front of a singing gargoyle.
** In "100 A.D." after Roger puts some amphetamine droplets in his eyes and eats some expired cheese puffs he hallucinates that Klaus is Garfield in a bowl and Steve is a walrus in a Nazi uniform.
* ''WesternAnimation/{{Amphibia}}'': In "Stake Out", Hop-Pop and Anne dare each other to try the other's respective pick-me-ups (a whole pot of Hop-Pop's "wart tea" and a bottle of energy drink Anne brought from the human world), the possibility that such drinks aren't biochemically compatible not occurring to them until it's too late. The result is a vivid shared hallucination that lasts for much of the rest of the episode.
* In the ''[[WesternAnimation/TheAngryBeavers Angry Beavers]]'' episode "Up All Night II" the eponymous beavers both suffer from lack of sleep. HilarityEnsues as the two beavers begin talking weirdly, acting weirdly and eventually even hallucinate the more and more their rational thinking starts to suffer due to lack of sleep. The episode's even more hilarious if you watch it while you are tired yourself.

** The entirety of the episode "Nightmares and Daydreams". Note to people with no knowledge of why one should not stay up for three days: [[TruthInTelevision sleep deprivation makes your brain self-produce DMT]]. The dreams that cause the sleep deprivation are pretty weird as well (Aang with a BadassLongcoat and AnimeHair?). The crazy comes to a head when Aang imagines that Momo, a tiny TeamPet, is talking to him. This is followed by Appa, who is a giant, six-legged bison, talking along with the other characters as if it's perfectly normal, to the point where Aang ''doesn't notice''. After Momo and Appa suddenly don Samurai garb and start fighting with swords, Aang declares his desire to dive under a cold waterfall.
** There's also Sokka and Momo's infamous trip from "The Desert", where they drink some [[AllDesertsHaveCacti cactus]] juice in order to quench their thirst while wandering around in the heat. The problem? The cactus was poisonous and had ''something'' in it (probably [[https://en.wikipedia.org/wiki/Mescaline mescaline]]), causing them to hallucinate (among other things, Sokka believed Toph was on fire) and cause them to act just a ''little'' off-kilter.
* ''WesternAnimation/BeavisAndButtHead'': Excessive caffeine or sugar was enough to turn Beavis into his psychotic alter ego "The Great Cornholio". Likewise, see TheMovie above.

** "Burgerboss" has Bob popping pain pills for carpal tunnel brought on by excessive videogame playing. He sees the bullies of his young mentor as characters in the 8-bit game and furiously chases after them.
** In "An Indecent Thanksgiving Proposal", while cooking Thanksgiving dinner with his family posing as his landlord's family, Bob gets drunk on absinthe and has a glorious hallucinatory vision of a perfect holiday riffing off ''Anime/MyNeighborTotoro''.
* ''WesternAnimation/BoJackHorseman'' has this appear in the first season, "DownerEnding", where the titular horse takes drugs in an attempt to get over his writer's block.
** Also happens in the season five episode "The Showstopper". As a result of Bojack abusing painkillers throughout the season, he's unable to distinguish reality from fiction for the entire episode, culminating in [[spoiler:nearly strangling his co-star to death on set.]]
* ''WesternAnimation/CelebrityDeathmatch''; when an accident [[AdventuresInComaland sends Nick into a coma]], he has a bizarre morphine-fueled dream of Music/ElvisPresley and [[Music/TheGratefulDead Jerry Garcia]] fighting in the Deathmatch ring to the tune of the song "Kung Fu Fighting".
* In the episode "Raisin The Stakes" on ''WesternAnimation/CloneHigh'', an anti-drug speaker tricks the entire high school into believing that raisins are a hallucinogen. Many drug montages take place of varying degrees of weirdness. (The entire episode is a rock opera ripped off from ''Music/TheWall'' and ''Theatre/JosephAndTheAmazingTechnicolorDreamcoat'' with traces of ''{{Theatre/Godspell}}'' and ''{{Theatre/Hair}}'' -- very '60s-'70s.)
* ''WesternAnimation/{{Daria}}'': "The Teachings of Don Jake" has the Morgendorffer family (except Daria) losing their marbles on a camping trip by eating psychotropic berries (which Quinn calls "glitter berries"). They'd probably still be chasing the spirit animal if Helen hadn't brought her cell phone...

** One occurs in "Seahorse Seashell Party" when Brian suffers nasty hallucinations after eating some bad psychedelic mushrooms.
* ''WesternAnimation/FinalSpace'': In episode 3, Gary starts getting these hallucinations when he eats a Moonobump. Avocato saves him with an injection.

** "Hell Is Other Robots" has Bender "abusing electricity", which is apparently that universe's robot-drug. Not only is it very addictive, but the first time he takes a hit he has a wonderful but brief hallucinatory trip.
** Also, in the episode "The Farnsworth Parabox", the crew visits Universe 420, a universe where everyone is on drugs. We don't get to explicitly see anything there, but the main story of the episode is mind-trippy enough in its own right. As Fry says about the situation: "It's like that drug trip I saw in that movie while I was on that drug trip."
** Almost the entirety of the episode of "The Sting", combined with AllJustADream. [[spoiler:It's revealed in the end that the majority of the episode was Leela's dream while she was in a coma after getting a dose of venom on the bee's stinger that scratched her.]]

** In Season 1 episode "[[Recap/TheGreatNorthS1E10GameOfSnownesAdventure Game of Snownes Adventure]]", when Beef starts catching a cold, Judy decides to give him some cold medicine. When Judy discovers the medicine is expired, Beef believes medicine can't expire and still drinks it in large doses, resulting in him seeing hallucinations while he tries to rescue Wolf and Honeybee. When he reunites with his family in the blizzard, he thought he left the house 30 minutes ago but they reveal he left three hours ago.
** In Season 2 episode "[[Recap/TheGreatNorthS2E10DipTheHallsAdventure Dip the Halls Adventure]]", Beef and Jerry drink some Terry Claus' famous punch to give them [[LiquidCourage confidences]] to mingle with the partygoers only to discover the punch has zero alcohol and is filled with hallucinogenic mushrooms and they start tripping out.
* ''WesternAnimation/HiHiPuffyAmiYumi'', "Rock and Roe": After eating too much sushi at a cheap seafood restaurant, Ami and Yumi start hallucinating.

* This has happened a couple of times in ''WesternAnimation/KingOfTheHill''.
** In "Hillenium," Hank accidentally inhales some varnish while working on a grandfather clock ([[TooDumbToLive Hank should have known better than to close the garage door when working with chemicals that can cause hallucinations and brain damage when used frequently and in a closed space]]) and he hallucinates that he, his family members, and his hero Tom Landry are mechanical moles in a whack-a-mole game.
** In "To Kill a Ladybird" although we don't see his point of view Dale under the influence of wild mushrooms describes cartoon characters dancing around his head when he closes his eyes, that harmless animals are out to kill him, and that Hank is spewing bugs from his mouth.
** In "The Son Also Roses," the two stoners hallucinate that Hank has an enormous head, many mouths, and has a distorted voice.
** We even saw a pig's hallucination in the episode "Lost in Website/MySpace." From his perspective, the colors of everything change from one palette to another.
** "Night and Deity" briefly shows a pigeon's point of view after being fed a drug, where it sees a distorted Bill and Boomhauer.
** "Returning Japanese" Part 1 has Hank and the guys in a sauna run by John Redcorn, who says that things might get a bit "trippy." Sure enough, Dale hallucinates being in bed with a preying mantis that beheads him, Bill sees himself riding a motorcycle naked and jumping in to a pie, Hank just experiences his father finally coming to good terms with him and switching to propane, and Cotton [[spoiler:sees the men he killed from World War II as zombies coming in and ganging up on him]].

-->'''"Trinket"''': Dayum, girl! You are super fucked up!
* In ''WesternAnimation/TheLittles'' episode "Prescription For Disaster", when Angela's mother drops her pill into the vent, it breaks open and lands in a pie Dinky is eating, he then hallucinates that his cousins are weird shapeshifting monsters and Grandpa Little is an abominable snowman, he runs away in fear while Grandpa chases after him, as he prepares his balloon to make his escape he sees it as a giant clown, he winds up in a cookie factory and sees the gingerbread cookies as members of his species and the oven as a giant fire monster that wants to eat him.

* In the ''WesternAnimation/OKKOLetsBeHeroes'' episode "Plaza Alone", KO, Rad, and Enid get trapped together in the bodega's break room. The scene that follows [[SurrealHorror becomes surreal and mildly disturbing]] as they suddenly begin to hallucinate. Things intermittently take on a neon color scheme, Rad becomes a hot dog, KO eats him and turns into a horse, and Enid becomes a large floating head and explodes. And during all the weirdness, the characters panic and argue, and KO remembers a documentary he watched earlier involving a lonely hero losing their mind and becomes depressed.

* In the ''WesternAnimation/PhineasAndFerb'' episode "The Ballad of Badbeard", Candace starts hallucinating wildly thanks to some weird moss. She ends up following Perry on one of his missions, all along thinking she's just dreaming the whole thing.
-->'''Candace:''' Why do my nostrils whisper to me..?
* ''WesternAnimation/RegularShow'' has one of these in "Weekend at Benson's" as the result of Mordecai, Rigby, and Benson drinking [[BlazingInfernoHellfireSauce a super-spicy concoction]] known as "Mississippi Queen". The song of the same name even plays during the hallucinations.
* In the ''WesternAnimation/RockosModernLife'' Halloween episode "Sugar Frosted Frights", Filburt eats Halloween candy for the first time and enters a sugar-rush-induced fantasy inspired by the "Night on Bald Mountain" segment from ''WesternAnimation/{{Fantasia}}''.
* In the ''WesternAnimation/ScoobyDooMysteryIncorporated'' episode "Night Terrors", the gang stays at a mansion, and starts seeing terrifying hallucinations (also, Daphne [[KissingUnderTheInfluence sees Shaggy as Fred and kisses him]]). It turns out that the firewood the mansion was using was Terror Wood, which releases hallucinogenic chemicals into the air when burned.

** [[Recap/TheSimpsonsS8E9ElViajeMisteriosoDeNuestroJomer "El Viaje Misterioso de Nuestro Jomer (The Mysterious Voyage of Homer)"]]: After eating some of "the Merciless Peppers of Quetzalzacatenango" at a chili cookoff, Homer starts hallucinating wildly (which Marge mistakes for Homer breaking his promise about getting drunk) and goes on a journey to find his soulmate at the behest of a talking coyote. This is actually TruthInTelevision, as eating sufficently spicy foods ''can'' cause hallucinations.

--->'''Chief Wiggum''': "The merciless peppers of Quetzalzacatenango! Grown deep in the jungle primeval by the inmates of a Guatemalan insane asylum."
** In "Worst Episode Ever", Homer eats a box of ancient bicarbonate of soda (baking soda) ("I think it came with the house," comments Marge) on a dare from Bart, which causes him to have an "antacid trip" (and Bart to win $50).
** In "D'oh-in' the Wind", where Homer becomes a hippie, Flanders starts seeing [[Music/TheGratefulDead Grateful Dead]]-type bears, [[Music/TheWall Pink Floyd's Marching Hammers]] and [[Music/TheRollingStonesBand Rolling Stones]]-type lips after drinking carrot juice laced with peyote. Barney sees a fanged monstrosity from the same drink, but is quickly saved by a beer and his friend Pinky, the pink elephant, Grampa and Jasper begin giggling like Beavis and Butt-Head (while sitting on a park bench in the same manner as Beavis and Butt-Head on their couch) and Willy sees a beautiful woman whom he starts kissing (which is actually a rake and the kissing is actually Groundskeeper Willy scraping his face with the tines of the rake).
** In "Homer Loves Flanders," Homer comments that Shelbyville threatened to spike Springfield's water supply after Springfield burned down their city hall, but they didn't have the guts. Cut to Marge drinking some water in the kitchen. Sitar music suddenly plays and Marge comments that the walls are melting again. A cooked turkey pops out of the oven and flies away.
** In "Selma's Choice", Bart dares Lisa to drink some of the "water" from a boat ride at Duff Gardens (which is so polluted, it doesn't really look like water anymore -- either that or the "water" is actually beer, though its effects seem more like Hollywood LSD than beer). Once she does, she starts to hallucinate (starting with the Dutch dolls on the "Little Land of Duff" ride receding down a dark, endless hallway), becomes paranoid after seeing a monster grow from Selma's arm, tries to whack Bart and Aunt Selma with a boat oar, stumbles around the Duff Lite Parade commenting on how she can "see the music," and is found hours later after security saw her swimming naked in the Fermentarium, clad in only a towel and declaring herself, "[[Music/TheDoors The Lizard Queen.]]"
** In "Weekend at Burnsie's", when Homer starts smoking medicinal weed, he opens his bathroom's door with a '60s-style happy face, grabs a razor with a happy face, sees rainbows coming out of his beard, and then he gets on his car (with a happy face too!), under a pink sky and the smiling sun, his car takes off, and he drives away -- all with Donovan's "Wear Your Love Like Heaven" playing.
** There was also a subversion: in "Missionary Impossible", where Homer becomes a missionary, he starts [[ToadLicking licking hallucinogenic toads]] out of sheer boredom; however, the only thing we can see is his dilated pupils and his unusual reactions.
** In "I'm Goin' to Praiseland", where Ned opens a Christian theme park. He erects a statue of his late wife (the park was a lifelong dream of hers), and people who stand in front of it are hit with a vision of their idea of heaven, while onlookers see them writhing on the ground speaking in tongues. Everyone thinks it's something truly spiritual until Ned discovers a gas leak near the statue and that people were just "getting goofy off the gas fumes."
** In "Boy Scoutz 'N The Hood" where Bart finds a twenty-dollar bill. He and Milhouse buy an "all-syrup Squishee," which causes them to [[GRatedDrug behave drunk]] out of an extreme sugar rush and also causes the show to segue into one of the most memorable songs of the series. And towards the end of the song, it causes the boys to ''hallucinate''. [[spoiler:In reality, they end up joining the [[SuspiciouslySimilarSubstitute Junior Campers]].]]
** Also, in the episode "Homerpalooza" Otto hallucinates that his shoes are talking to him.
-->'''Otto:''' Don't worry, I won't hurt you. I only want you to have some fun.
** In "Bart Gets an Elephant", after sniffing some ammonia fumes Homer hallucinates that the cleaning mascots come to life and start dancing around causing him to laugh. Suddenly they spring out and attack him causing him to scream, Marge hears this and tells him to stop screaming so loud.
** In "Team Homer", Mr. Burns sees Homer as the Pillsbury Dough-boy while under the influence of ether, and since he's a big fan of his Homer uses this to get money for his bowling team from Mr. Burns. Burns then sees Hans Moleman as Lucky the Leprechaun, and tries to kill him and steal his brain to figure out the secret of his Lucky Charms.
-->'''Hans:''' [[MajorInjuryUnderreaction Oh no. My brains.]]
** In "King of the Hill", when Homer is climbing the Murderhorn mountain, he starts feeling light-headed from the thinning atmosphere, then eventually says "Why should I climb when I can just take the escalator?" He then hallucinates that he's riding up the mountain on an escalator dressed in a suit and top hat, then leaping from peak to peak on the back of a blue mountain goat, then getting an elevator ride from the Abominable Snow-Monster from ''Rudolph the Red-Nose Reindeer''. Back in reality, he's actually tumbling down the mountain all cut up with a big smile on his face.
** In "Last Exit To Springfield" Lisa under the influence of laughing gas hallucinates that she is flying through the air and comes across a parody of Pepperland from ''WesternAnimation/YellowSubmarine'' and meets Music/TheBeatles in a purple submarine.
** In "Married to the Blob" ([[SimilarlyNamedWorks the season 25 episode, not the "Treehouse Of Horror XVII" segment]]), Homer and Mr. Nakamura get drunk on potent rice wine and have a Creator/HayaoMiyazaki-inspired hallucination.
** "The Good, the Sad and the Drugly" has Lisa put on anti-depressants, causing her to hallucinate smiley faces on everything. Maggie nearly gets her to kiss a fan under the influence.
** In "The Bart of War", Bart and Milhouse have some 40-year-old [[Music/TheBeatles Beatles]] sodas, Bart, trying the "John Lemon" soda, imagines Milhouse as Music/JohnLennon in the different phases of his life, from Beatlemania to Sgt. Pepper to "Let It Be" to "Double Fantasy".
** In "Bull-E", Otto hallucinates twice. First, he hallucinates about hitting the "I Choo-Choo-Choose You" train with a Ringo Starr-esque voice (parodying Thomas the Tank Engine), and at the end, hallucinates about the orange Magic School Bus, driven by Ms. Drizzle (a parody of Ms. Frizzle).
* ''WesternAnimation/SouthPark''
** All the boys (including Jimmy, Butters, and Token, but not Kenny) take hits of cough syrup in "Quest for Ratings," assuming that the wild hallucinations are bound to give them plenty of ideas to improve their school news show. They certainly have fun with the hallucinations, but the only "ideas" they emerge with are some squiggly lines and a circle drawn by Cartman and all the lyrics to the ''Series/HappyDays'' theme song written by Kyle.
** The episode "Major Boobage" had Kenny getting high off cat urine and tripping out into a ''WesternAnimation/HeavyMetal''-style hallucination where there are breasts ''everywhere'' (even in the architecture!) Kyle's dad later takes a hit of cat pee, culminating in the two duking it out half-naked in a sandbox. At the end of the episode Kenny gets high on a bunch of flowers.

** In "Star Comes To Earth", Star defeats [[BigBadWannabe Ludo]]'s minion Buff-Frog by stunning him with a "Jellybean Hallucination Mist", which causes him to see faces appear on the palms of his hands.
-->'''Buff-Frog:''' I'm ''freaking out!''
** In "Goblin Dogs", when Star, Marco and Pony Head finally eat the titular food, they're initially underwhelmed, thinking they're just ordinary hot dogs. Then they all experience a trippy rainbow-colored vision and agree that goblin dogs are the best hot dogs in the universe after all.
* Similar to the RealLife example below, in ''WesternAnimation/StarWarsCloneWars'', Anakin Skywalker gets a blast of steam in the face in a cave on Nelvaan. As a result, he starts seeing the cave paintings move. Considering how well the vision summarizes and foreshadows his own fall to the Dark Side, The Force probably assisted the lack of oxygen.\\\
This sequence parallels Luke's experience in the cave in ''Episode V'', where he receives a similar vision/warning about his own susceptability to the Dark Side. [[spoiler:Not counting his fall(s) in the Expanded Universe, Luke would seem to have payed more attention to this warning.]]
* ''WesternAnimation/TeenTitans'':
** The episode "Haunted" features a rare serious example. Robin accidentally inhales an unnamed hallucinogen from an old mask of Slade's. Unlike most examples, however, this Mushroom Samba leads to what most fans consider the darkest episode of the series. Robin hallucinates that Slade (believed dead at the time) is everywhere and goes on a rampage trying to stop him, even going so far as physically hurting Starfire (his best friend and love interest) and threatening to "[[NeverSayDie take down]]" his team if they try restraining him. The drug manifests [[YourMindMakesItReal every blow on his body as though he really is battling someone]], and so before he realizes that bright light disperses the visions, he's nearly beaten to death...by himself. The Titans are convinced Robin has gone insane until Raven mind-links with him and Slade punches ''her''. The scariest part? The hallucinogen didn't activate on its own. It was triggered by someone using a remote ''from outside the tower''.
** A less serious but still scary example: in "Crash", Cyborg gets his turn when Beast Boy accidentally gives him a computer virus. He then rampages crazily through town and [[ExtremeOmnivore eats everything in sight]], while having strange [[MeatOVision food-related hallucinations]].

** At one point, the team approaches him cautiously, and he sees them as giant eggs!
--->'''Starfire:''' You remember who we are, yes?\\

** Heck, earlier in the episode, he tried to eat Robin, seeing him as giant ribs!
--->'''Robin:''' Cyborg, there's clearly something wrong with you!\\
'''Cyborg:''' You bet there's something wrong! ''We need gravy'' '''''AND PLENTY OF IT!!!'''''

* One of the Shen Gong Wu in ''WesternAnimation/XiaolinShowdown'' is the Woozy Shooter, a horn that produced a purple smoke that causes intense hallucinations and irregular behavior in anyone who inhales it.
