The characters are costumed
, their houses are decked out haunted mansion style, they tell spooky stories, and weird (or weirder than usual) things abound! It's the yearly Halloween
Probably the most well known of these are The Simpsons
"Treehouse of Horror
" episodes, but most American kids' and genre shows have them. While neither Samhain nor All Saints Eve
is ever mentioned, the similarly themed (but more upbeat) Dia de los Muertos (Nov 1-2) might be if the characters are on a visit to Mexico.
If it's too
scary (or rather, too successful
), this may result in Nightmare Fuel
. Often a Bizarro Episode
as well. Either way, coming across a Halloween episode of a show you watch in syndication is often an unexpected treat.
If the cast ends up in Halloween costumes, expect at least some of them to be a Shout-Out
or even the occasional Actor Allusion
There's a subversion/reversal on supernatural-oriented series where Halloween is literally
a holiday for supernatural beings, and they all stay home. (Some Fridge Logic
here because this assumes that terrorizing the populace is a job
for supernatural creatures, rather than leisure activity.)

At the end of the story a huge fireworks display is shown over the city with a good old fashion Happy Halloween scrawled in the sky.
- The Whateley Universe had a big Halloween spectacular for the fall of 2006 (Whateley time), when everyone dressed in fun costumes (Phase hated his)... and the campus was attacked by cyborgs, robots, and dropships full of Syndicate badguys.

- The original Woody Woodpecker Show got a Halloween Special called Spook-A-Nanny. It's included as an extra on the first Woody Woodpecker And Friends DVD collection, and worth watching for its cheese factor. Oh, and ghosts wearing Beatle wigs. No, really.
- Donald Duck starred in a bunch of shorts with a semi-scary atmosphere, such as Donald Duck and the Gorilla, Donald's Lucky Day, and Duck Pimples, but the true Halloween episode is fans' favorite Trick or Treat, where Donald's assholish treatment of his nephews leads to a witch helping the boys to get the best of their uncle.
- Mickey's House of Villains could be considered a Halloween episode of House of Mouse.

The rest is your usual HOM stuff, with showing scary shorts instead of the usual upbeat ones.

- T.U.F.F. Puppy: Happy Howl-O-Ween episode has the villains stealing Halloween candy, and Keswick creating an army of zombies who are craving for candy.
- The Adventures of Jimmy Neutron takes great pleasure in pushing this trope to its stereotypical limit. In the episode, Jimmy creates a monster wheel designed to turn his friends into authentic monsters (a closer examination of the wheel shows Michael Jackson as an option) - the only problem is, the invention works a little too well, and Carl and Sheen end up as a real vampire and a real werewolf. They bite Cindy and Libby, who then join the ranks of bloodsuckers/flesheaters, and before you know it the whole town is out for a good ol' fashioned monster-mob.
- CatDog: Dog gets bitten by Peruvian vampire ticks, so Cat tries desperately to find a cure. In the process, their friends are also bitten by the vampire ticks and turned into vampires.

- Pinky and the Brain: Pinky sells his soul to the Devil so that Brain can take over the world. Brain then challenges Satan to a gymnastic competition for Pinky's soul, and loses. However, when Pinky signed the contract giving his soul to the Devil, the Devil forgot to give him some sort of gizmo (with a really weird name and a vague explanation of its function), thus rendering the contract null and void, and saving Pinky's soul.
- Tiny Toons' Night Ghoulery: A parody of Rod Serling's Night Gallery with Babs Bunny in the Serling role.

Another is a parody of Abbott and Costello Meet Frankenstein, with Buster Bunny and Plucky Duck as the titular duo, respectively. The final story is a parody of The Twilight Zone episode "Nightmare at 20,000 Feet", with Plucky as the William Shatner character and the gremlin from the Looney Tunes short Falling Hare as the monster (it also, to some extent, spoofs the final segment of Twilight Zone: The Movie).

- There have been a few in South Park.

- The Spectacular Spider-Man has one of the most plot important episodes as a Halloween episode. It involves plot advancement on who the Green Goblin is, and it is actually the set up for another episode when Peter arrives in his Spidey suit.
- On Home Movies the gang was on their way to a Halloween party but they all ended up at the hospital when Brendon's stepmom went into labor and Coach McGuirk had a heart attack. Not the best place for Melissa to dress like the Grim Reaper.
Coach: Omigod, it's Death.
Melissa: Coach, it's me, Melissa!
Coach: Omigod, it's Melissa.
- The Magic School Bus had a Halloween special that was two spookily themed episodes from the series tied together by a live-action sequence where an old caretaker told two kids terrifying stories about kids learning about sound and bats.
- Celebrity Deathmatch had two Halloween episodes with matches such as Frankenstein's Monster vs. the Wolf Man, The Undertaker vs. Captain Doody (a demon possessing Nicky Jr.), and Sarah Michelle Gellar vs. a vampire.
- The Cleveland Show had "It's the Great Pancake, Cleveland Brown", where Cleveland upsets Cleveland Jr. by telling him he is too old to trick or treat and Rallo eats too much candy.

- Phineas and Ferb has a few.
- While not taking place during Halloween, "One Good Scare Ought to Do It" and "The Monster of Phineas-n-Ferbenstein" aired in October for Season 1.

- Season 4 has "Drusselsteinoween" and "Face Your Fear", the first one has Vanessa throwing a Halloween party in the castle her father inherited. The second one was about Doofenshmirtz creating a machine that cause animals to grow bigger and he tested it on a bat which he is afraid of. Like before only the first one was on Halloween.
- Another episode is "Terrifying Tri-State Trilogy of Terror", which just like the Simpsons Tree House of Horror series was in a three shorts format. Although the shorts were not Halloween themed, they did air in October.
- As part of a special series that ran throughout October 2011, Cartoon Network premiered new Halloween themed episodes as part of their Monday night scheduling block. The five shows participating were Johnny Test, The Amazing World of Gumball, Adventure Time, Regular Show and MAD. The other show, Secret Mountain Fort Awesome, did not participate due to the sheer newness of S.M.F.A. The premieres culminated on Halloween Night (which fell on a Monday) in which each episode was shown during a marathon.
- Regular Show had "Terror Tales of the Park", à la Treehouse of Horror, consisting of a series of smaller episodes. In true Treehouse of Horror fashion, none of the episode is canon. The first part of the episode is about a Victorian age doll named Percie that Pops had as a child who has a compulsive need to draw on people's faces, which climaxes as the doll comes to life and attempts to kill Mordecai, Rigby and Pops to fulfill his need. The second part features Muscleman and High Five Ghost as they plan to crash an RV into a bottomless pit only to find the late owners, a metal band named Skull Bash, have not left. The third part features Mordecai and Rigby trick-or-treating. Rigby eggs the Halloween Wizard's house and pays for his crime. It is revealed that the entire story was told by the Halloween Wizard, disguised as Rigby the entire time.
- The following year had "Terror Tales of the Park II" which had the same format of three separate shorts, but had a framing device to link them all together; in this case, the Park staff are on a journey to a Halloween party and tell the stories to pass the time. Mordecai's story, "Payback", involved Mordecai accidentally killing his Uncle Steve, and Uncle Steve's corpse subsequently haunts Mordecai to settle his Unfinished Business. Margaret's story, "Party Bus", has Mordecai, Rigby, Margaret and Eileen take the "Party Bus" to the movies instead of their late taxi; however, as the party on the bus proceeds and the other guests start to collapse from partying too hard, they realize that this party's a killer. The final story, told by Benson, is "Wallpaper Man", an homage to Stephen King's story ''The Lawnmower Man". Mordecai and Rigby are tasked with applying new wallpaper to the house but they are swayed by a television offer from Jan the Wallpaper Man, who will wallpaper an entire house for free. However, Jan's sinister red-and-black wallpaper turns the house's interior into a claustrophobic maze, with the other park employees trapped in the center. Mordecai and Rigby must rescue their co-workers and confront Jan, who has a dark agenda and a monstrous secret...
- The Johnny Test episode is titled "Johnny Trick or Treat". Johnny accepts a dare by a mysterious card impaled on his door. In order to see a real haunted house and cash in on a large amount of candy, he must spend a night in a house and wear a tutu. He is joined by Dukey and Jillian, only to find the house is rigged with traps. They successfully complete all of the tasks, only to be eaten by a giant maggot. With Jillian in danger, the master of the house, Darth Vegan, tries to save them, only to have his plans ruined. When it is revealed that there was no candy, Johnny and the rest of the crew teleport to a party attended by Susan, Mary and Agents Black and White, where he wins a candy making machine for first place in a costume contest.
- The second Johnny Test episode called "The Johnny Who Saved Halloween". Johnny and several other kids are in a contest to collect the most candy in order to win a literal mountain of candy.
- Adventure Time parodies Clue and And Then There Were None in the episode "The Creeps". Members of the cast are assembled at a mountain-top castle. Each of the characters gains an alias as part of the invitation:
- Finn as Prince Hotbod
- Jake as Randy Butternubs
- Princess Bubblegum as Lady Quietbottom
- BMO as Professor Pence
- Lumpy Space Princess as Duchess Gummybuns
- Cinnamon Bun as Guy Farting.
- The costume party goes awry as characters are killed off and the party turns into a mystery when it is revealed that a ghost has possessed one of them and intends to murder them. Jake and Lady Rainicorn reveal that they are the ghost and that none of the character were killed. Finn asks how Jake got the house to come to life. Jake doesn't know what Finn is talking about and the crew leaves the castle. Finn keeps the memory in "his vault" .
- A second Adventure Time Halloween special, "From Bad to Worse", aired a week later. The episode deals with a Zombie Apocalypse and is a continuation of the premiere "Slumber Party Panic". Finn, Jake, Rainicorn and LSP are seen running through the Candy Kingdom avoiding the now zombified denizens. After making it to the castle, Princess Bubblegum explains the infection is her and Cinnamon Bun's fault. Princess Bubblegum says she will make the antidote again but before she can, she is bitten by a zombie. Before being changed, she tells Finn to let science do the work to create the formula again. It is up to the four to create the formula. In an Eureka Moment, Finn realizes that PB's last words meant for them to use Science, the lab rat. The lab rat creates the formula and Finn tests in on Jake who returns to normal. Unfortunately, the effects are reversed after Jake is bitten again. Out of ideas, Finn covers himself in the antidote and flings himself into the fray and is chewed by the zombies. The last scene shows the Candy Kingdom fully cured, Finn in a state of well-being and Princess Bubblegum awarding Science with a medal for heroic bravery.
- The Amazing World of Gumball has the episode simply titled "Halloween". Carrie the ghost helps get Gumball and Darwin into a ghosts-only Halloween party using ghost potion. However, an overdose of the potion turns Gumball and Darwin completely into ghosts, triggering a Cosmic Deadline to get them back into their bodies or else they'll be dragged into the underworld. To make matters worse, Anais also drinks the potion and Gumball must save her as well.
- MAD had the episode "Kitchen Nightmares Before Christmas/How I Met Your Mummy". Within the episode were Nightmare Before Christmas and How I Met Your Mother references, as the title implies. Other references included ScreamX20, Scooby Doo: Ruining Halloween Since 1969, and VeggieTales from the Crypt.
- While not necessarily Halloween material, some episodes that premiered did contain horror elements.
- Regular Show "Camping Can Be Fun"
- The Amazing World of Gumball "The Poltergeist"
- Kick Buttowski had the predictably named "Kick Or Treat", where Kick accepts a challenge from Kendall to go trick-treating at the scary Old Dark House across the street. Turns out the house is owned by a nice old lady who loves Halloween so much that she went completely overboard with the special effects.
- My Little Pony: Friendship Is Magic has "Luna Eclipsed" where the ponies celebrate the day as "Nightmare Night" and a certain literal Ensemble Darkhorse shows up, being determined to change her frightening public image she made back in the past. At first, it wasn't really working out all that well for her, and it goes to the point where she ends up decreeing the cancellation of Nightmare Night forever! However, Luna eventually learns that the young ponies actually like being scared by her, and she declares that Nightmare Night's back on.
- The Backyardigans episode "Scared Of You" is this in all but name.
- W.I.T.C.H. had "W is for Witch", in which the girls were able to get away using their Guardian identities in public in order to capture Nerissa. However, thanks to the series' serial storyline, when Toon Disney elected to air this during a Halloween-themed marathon, it was shown earlier than it was supposed to be, effectively spoiling viewers to a number of future plot points.
- American Dad! did one of these where Stan tried to outdo his neighbor's haunted house. His solution? Bring in caged serial killers. And then Roger frees them...
- Family Guy only has one, oddly. It was from season 9, where Chris and Meg went to a party, Stewie and Brian dealt with a bully that stole Stewie's candy and Quagmire getting revenge for a prank by Peter and Joe. Lois becomes the bully for the bullies and actually scares Stewie a bit, Quagmire pretends to be possessed by a Japanese World War II pilot, and MEG AND CHRIS ACCIDENTALLY MAKE OUT WITH EACH OTHER.

- Danger Mouse had "The Good, the Bad and the Motionless," which took place on Halloween, as DM tells Colonel K that Penfold is carving up a swede.
Colonel K: Good heavens, DM. I didn't know he could play tennis!
D.M.: Tennis? Oh, no. Not Bjørn Borg, sir. Not that sort of swede. It's the vegetable kind.
- The Beetlejuice cartoon's Halloween episode, "Laugh Of The Party," had B.J. livening up Lydia's Halloween party with Party People In A Can. They're all Neitherworld denizens, so the party was rather unorthodox, even for Halloween. A year later, the episode "Bewitched, Bothered and Beetlejuiced" had Lydia dressed as a witch for Halloween, only for her cat Percy to get catnapped by a soiree of witches.
- Recess had "The Terrifying Tales of Recess", which was similar in structure to "Treehouse of Horror" (but more G-rated), possibly because a good amount of the Recess staff worked on The Simpsons.
- The TV-movie "Taking The Fifth Grade" had its third segment taking place on Halloween where Spinelli decides she's too old for Halloween traditions and nearly ruins it for her friends.
- The Weekenders has Tino's friends refuse to go trick-or-treating with him so he comes up with an elaborate prank to scare them on Halloween anyway.

Pepper Ann and Milo go in spite of this, and an ending montage reveals that their classmates secretly joined in.
- The Gravity Falls episode "Summerween" explores Summerween, a second Halloween in the summer because Gravity Falls loves the holiday that much. Soos tells the legend of the Summerween Trickster, a phantom who kills those who do not accept the holiday. Dipper, wanting to attend a party instead of trick-or-treat, attracts the Trickster who holds the lives of he and his friends in the balance in exchange for five hundred pieces of candy. Knock knock, indeed.
- "The Smurfs Halloween Special" was really a regular Saturday-morning cartoon episode, and it was mostly about celebrating Jokey's birthday, though one of the subplots is that Hogatha the witch wants to celebrate Halloween by scaring little children, only for her holiday to be ruined by one of Gargamel's spells. There's also "Monster Smurfs", where the Smurfs celebrated a similar holiday called Spook-A-Smurf Eve.
- The sixth episode of Jackie Chan Adventures' fourth season, "Fright Fight Night" is set on Halloween, dealing with Paco being possessed by one of the Oni masks and the heroes having to get it off before Tarakudo is able to corrupt him.
- All Grown Up!'s Halloween Episode had Chuckie freaking out over the possibility that Tommy might have a crush on Kimi and so running off on his own on Halloween when there's dangerous teenage gangs about.
- The show also had two other horror-themed episodes that would have fit this trope, only they weren't set on Halloween. "Curse of Reptar" was an Affectionate Parody of Poltergeist and "Interview With A Campfire" had the kids get lost in a colonial mine that was said to be haunted.
- El Tigre episode "The Grave Escape"; Taking place on Dia De Los Muertos, Manny feels he's getting too old for the holiday (Despite his father and Grandpapi being all for it) when Sartana of the Dead attacks with a monster formed from Miracle City's unremembered dead("Sartana of the Dead!?" Cries Rodolpho, "Attacking on the Day of the Dead!? Actually, that makes sense."). Manny and Frida end up getting sent down to the Land of the Dead, where they recruit Riveras from the past to get back to the surface in order to defeat Sartana, including the original El Tigre, which does prove that (For Manny) indecision does run in the family.
- Despite being predated by 4 months in the US and one month in Canada, the Grojband episode "Dance of the Dead" takes place during Halloween night.
- Bob's Burgers - one episode has the kids trick-or-treating without the parents for the first time. They take the ferry to the greener pastures of the island where the rich families live. Another episode has them miss Halloween altogether when they get stuck in their alleyway cardboard box fort at the mercy of a creepy classmate of Louise's.
- The Venture Bros. has the A Very Venture Halloween special. Interesting in that it is a Synchronous Episodes with the Season 5 premiere What Color is Your Cleansuit?, taking place entirely with the first "commercial break" of that episode. It also contains one of the biggest plot revelations in the series so far despite being a "special" episode, namely that Dean finds out that he and Hank are clones.
