The Pig Pen / Western Animation

• Adventure Time: Marceline generally couldn't care less about her personal hygiene, picking her nose, not washing her hands after using the bathroom, and commenting that her armpits stink.
• American Dad!:
  • Implied with Hayley. It's been pointed out several times that she reeks of body odor, which isn't unlikely given her rather lethargic demeanor. It's also revealed she eats out of the garbage; she is even shown picking her nose on several occasions.
  • Roger is often a Fat Slob who couldn't care less about cleaning up after himself.
  • Principal Lewis. His apartment is a complete dump and it's indicated he doesn't shower given the sweat stains on his undershirt.
• Avatar: The Last Airbender: While it's not her most notable characteristic, Toph Beifong likes to walk around in "a healthy coating of earth", partly because she's an Earthbender, partly to rebel against her posh parents.
• Beavis and Butt-Head: The titular characters care nothing about their personal hygiene. This is actually part of the plot of the episode "Tainted Meat". When Beavis' privates are itching like crazy, he can't stop scratching at Burger World, not even bothering to wash his hands before putting patties on the grill. Everyone who eats at Burger World as a result gets food poisoning, with health experts outright stating that they have never seen such aggressive bacteria.
• In the film, Beetlejuice was pretty grubby, but it was just another facet of how obnoxious he was. But in the Animated Adaptation he really cultivated it, showing actual pride in his stink.
• The wizard Zabobon from The Big Knights, who wears a filthy robe and is perpetually surrounded by flies.
• Giant Mook Greasepit from Biker Mice from Mars has some kind of mutation where he literally sweats motor oil & grease from his pores constantly. He makes a major mess wherever he goes, and often ends up tripping or causing others to trip because of the slime he drips all over the place.
• Bob's Burgers:
  • Bob is commented on several times to have lacking personal hygiene. People frequently take note of a smell that seems to follow him, and he himself admits he doesn't wash much.
  • Gene as well. In the Season 11 episode where he's patient zero for a family pinworm infection, it's noted that the Belchers thought he had a sunburn for a week when it was really just Buffalo sauce.
• Camp Lazlo: Chip and Skip are perpetually surrounded by flies and admit in one episode they don't bathe. According to "Dirt Nappers", they have to stay perpetually filthy lest they enter a century-long slumber.
• Captain Caveman and the Teen Angels: Captain Caveman is a big hairy ball of filth.
• Codename: Kids Next Door had a one-shot character named Captain James P. Dirt who apparently ran away from home to avoid his Neat Freak mother who wanted him to take a bath, and as a result, lives in the sewers as an adult never having bathed in his life, the captain of a ship full of dirty, lazy children. Numbuh Two's brother Tommy falls in with him, but eventually he finds this rather disgusting, and eventually he and the Captain see the error of their ways. James eventually tells Tommy before they part company, "Listen to your mother."
• In the Courage the Cowardly Dog episode "Conway the Contaminationist", a man named Conway (a filthy, deformed pilot) comes to the Bagge house, claiming that terrible hygiene is actually good for your health. Muriel and Eustace decide to live filthy lifestyles too, but it makes them sick and miserable. Conway himself actually does benefit from being dirty, though, as he drinks sludge to heal his injuries, and even claims to be 193 years old.
• Dan Vs.: Dan never showers or brushes his teeth. He even states that he only goes to the dentist once a decade. Not to mention that his apartment complex is an absolute dump, almost literally.
• Darkwing Duck: One-shot villain Ample Grime, who is also, ironically, the sister of Neat Freak villain Ammonia Pine.
• Getting dirty is one of Dennis the Menace (UK)'s secondary traits. In one episode of the animated series, he's shown to have an uncontrollable compulsion to get dirty. When his father threatens him with grounding if he gets messy before his school photo is taken, Gnasher has to keep dragging him away from messy situations.
• Ramon Ridley from Dogstar. A cleaning robot self-destructs after attempting to calculate exactly how much filth he has on him.
• Ed, Edd n Eddy:
  • Ed is perpetually filthy and terrified of soap. He also carries around a moldy chunk of cheese and a rancid fish skeleton for good luck.
    Ed: Bad soap, evil soap, slippery sudsy scary soap!
  • The Kankers are downplayed examples, but they appear as though they don't brush their teeth or keep up with their hygiene.
• Edgar & Ellen: One time in the animated series, Ellen got sprayed with an anti-bug formula, which made a bunch of bugs come jumping out of her hair.
• One of the episodes of Fanboy and Chum Chum deals with Fanboy trying to beat a record on going for the longest time without a bath. His costume got so incredibly dirty, it came to life and gained the personality of a mobster called Stinks.
• An episode of Fat Albert and the Cosby Kids had the gang deal with a kid named Suede Simpson who never bathed. The smell was so bad, no one wanted to be around him and he could never figure out why. Russell finally told him that he smelled. He was angry at first, but finally got the message and took a shower.
• French Roast: The homeless man is so filthy that a cloud of flies hovers over his head and follows him around. Of course, he is homeless.
• Dr. Zoidberg from Futurama. He lives in a dumpster and his dates dump him because of his stench. In a final season episode, he gets together with a woman with no sense of smell.
• Gravity Falls: While he's not usually visibly dirty, Dipper apparently has questionable hygiene, and part of the reason he wears the same outfit all the time is that he thinks doing laundry is "a waste of time".
• One episode of The Grim Adventures of Billy & Mandy featured Billy's mom Gladys going progressively insane as she repeatedly bathes Billy and dresses him in a clean tuxedo, only to have him get filthy within seconds by careening around the yard and playing with mud.
• In the Happily Ever After: Fairy Tales for Every Child episode "Snow White" one of the seven dwarfs was named Smelly Sulfur, he often rolled around in dirt and his stench would kill plants as he passed by them.
• Jason was this in the first season of Home Movies when the show felt like indulging itself in gross-out humor. To wit...
• Stumpy from Kaeloo refuses to brush his teeth every day and Hates Baths to the point where he bathes less than once a month.
• It is implied several times that Bill from King of the Hill has very poor hygiene and lives in very filthy conditions almost never cleaning up after himself, this is mainly due to being depressed after his divorce from Lenore.
• Daffy Duck is implied to be this in The Looney Tunes Show. In "That's My Baby", he says that he "cares about the Earth" when Tina points out that he doesn't shower, is revealed to have never heard of toilet paper in "Peel of Fortune", and in "Bugs and Daffy Get a Job", he refers to Bugs brushing his teeth as a "little quirk" (keep in mind that Daffy is a Toothy Bird) in defense of his snoring.
• The Loud House: Lana Loud loves living the gross life, whether it's playing in mud or rummaging through garbage. In stark contrast, her twin sister Lola is obsessed with beauty and cleanliness.
• The Dirt Dudes from Mr. Bogus are anthropomorphic dust bunnies that are depicted as being dirty and very mean.
• ¡Mucha Lucha! had The Flea, whose special wrestling move was really bad odor. His outfit is actually white, but his lifestyle is so dirty it's become consistently brown all over.
• Surprisingly a few in My Little Pony:
  • Several in My Little Pony: Friendship Is Magic:
    • In one episode, the song "The Perfect Stallion" briefly featured a filthy, smelly, fly-drawing stallion, whose cutie mark was a trash can.
    • In another episode, one of the booksellers at Starlight's childhood village says that she doesn't wish to cover up her natural scent. Cue her lifting up her arm and green waves coming from it.
  • Back in My Little Pony (G3), Spike was awakened from his thousand-year sleep and was as dirty as to be expected. He openly takes pride in how dirty he was and while everypony else is holding their noses, he implies he purposefully cultivated his horrid stench. However, after getting cleaned off he admits he's glad to be clean again.
  • In My Little Pony: A New Generation, Earth Ponies were stereotyped by the unicorns for "smelling like rotting sardines", to the point that Izzy Moonbow is legitimately shocked when learning that Sunny Starscout doesn't smell.
• The Powerpuff Girls (1998):
  • The episode "Down N' Dirty" has Buttercup repeatedly refusing to take a bath over the course of several fights that get her progressively filthy, to the point that the Townsville townsfolk chased her with Torches and Pitchforks, and even the episode's final Monster of the Week refused to fight her. That's what forces her to clean up at the end.
  • Harry Pitt from "Cootie Gras" is always seen covered in dirt, due to the fact he likes to play in the mud.
• In the Raw Toonage / Marsupilami short Bathtime for Maurice, Marsupilami tries to get his gorilla friend Maurice a bath.
• Regular Show:
  • Rigby. He sleeps in a pile of dirty clothes and reacted in disgust over taking a shower. Eileen also mentions in "Dumptown U.S.A." that he doesn't floss or brush his teeth, ever.
  • Muscle Man is even worse. He hardly showers, doesn't know proper table manners, and has a messy trailer.
• Rugrats: Phil and Lil loved to play in mud and garbage, and ate worms. They ate anything they could get their hands on. Lil eventually grew out of her habits, but as of All Grown Up!, Phil is the same.
• Though not her normal state, in the episode "Lather, Rinse, and Repent" of Sabrina: The Animated Series, Sabrina discovers a magical potion that locks her hair in a state of constant beauty, to the point it makes her the most popular girl in school, though its effects will permanently stop working if she gets wet while using it. Because of this, she stops showering, progressively becoming more and more visibly dirty throughout the episode, complete with flies buzzing around her and characters remarking how bad she smells. (Throughout this, however, her hair remains perfectly flawless.)
• Implied with the character Dirty Bill from the Silly Symphonies short "The Robber Kitten" although Ambrose the Kitten never comments on his smell, Bill states that he's never had a bath and never will, and at one point he is seen scratching and sniffing his armpit.
• The Simpsons: Homer has been implied in multiple episodes to have poor hygiene and an unpleasant odor.
• Implied in the case of Jude Lizowski from 6teen — in one episode, it's mentioned that he actually went two weeks without bathing of any kind. But fortunately for the rest of the gang (and, by extension, everyone else), Jude never smells too bad, which Jude claims is due to something that he refers to as the "Stink Cycle."
• Sloppy Smurf from The Smurfs.
• South Park had Dogpoo, an obvious Shout-Out to Pig-Pen, to the point of hardly being used at all in the show because of his one-note characterization (a problem Schultz also ran into when thinking up material for Pig Pen).
• Spongebob Squarepants:
  • Patrick Star picked up the Conflict Ball when he gained the status of Pig-Pen as a Compressed Vice. He turned against suddenly scrupulous neat freak Spongebob and they waged a war of cleanliness vs. filth for 11 minutes. They do a good job of implying that this isn't new, though; in one scene Spongebob removes Patrick's "jacket", only to discover that what has appeared to be his skin ever since the show started is actually a uniform layer of caked-on filth half an inch thick.
  • In the episode "Karate Island", one of the opponents Sandy faces is known as Filthy Phil who attempts to fight her using his body odor. However, Sandy is protected from his scent thanks to her "fresh air dome" and the stink is instead smelt by Phil himself.
    Filthy Phil: Man! I really do stink!
• Russel from Stickin' Around, who emitted a "funky smell" at all times.
• In the The Super 6 "Brothers Matzoriley" segment, the titular brothers had to deal with a recurring antagonist called Dirty Pierre, who was as filthy as he was malicious.
• In Taz-Mania, Taz isn't especially dirty (not most of the time) but he does hate taking baths, something that is mentioned in several episodes.
  Taz: Taz hate water!
• Ian "Eww-an" Wazselewski from Teacher's Pet.
• Guysborough the Garbage Barge from Theodore Tugboat loves garbage and hates being cleaned.
• Whiff and Scruff from Thomas & Friends are both engines who work at the Waste Dump. Scruff in particular hates being cleaned, though in the episode, "Scruff's Makeover", he became proud of his new coat of paint, and refused to work at the waste dump.
• Time Squad: Tuddrussel's slovenly nature is remarked on several times throughout the show. But it's not always a bad thing; in one episode, he has Amelia Earhart overcome her germophobic ways by teaching her how to be a slob.
• The Transformers had three characters who were known for this quality (at least in their toy bios — it didn't necessarily make it to the show). First, there's the Autobot targetmaster Landfill, who turns into a dump truck and doesn't ever quite understand that after hauling around a few loads of leaking hazardous material it'd be polite to use some cleaning agents on yourself. Then there's the Decepticon Terrocon Blot. In his case, the filth issue really isn't his fault: he's got problems with leaky connections that he just can't fix that leave him constantly dripping foul sludge. But the one who really takes the prize is the Decepticon Horrorcon, Snapdragon. Unlike the other two, he realizes how disgusting and foul he is and he revels in it. He loves to roll in whatever nasty spills he can find to ensure that he's got the worst stench possible.
• In the Mondo TV cartoon for The Trash Pack, ironically, the character that is considered the grossest of them all is not one of the Trashies, the living pieces of garbage. Rather, it's Mr. Binner, a surly businessman from Garden City. His white shirts are always stained, he has a green stink cloud that always follows him around, and his broken briefcase always drops out trash, which he simply kicks away instead of picking up.
• Lord Stinker from TUGS is a garbage barge who works with Warrior (and occasionally Top Hat). He wears a clothespin on his nose to escape smelling his own garbage.
• Stinkbert from Turbo Dogs
• Velma:
  • Diya, Velma's mother. Before Sophie moved in, the house stank of booze and was filthy in contrast with how the Spooner's Malt Shop owner kept things spotless and a dream home as described by Velma herself, who doesn't even like her dad's girlfriend. She was even stated as smelling like booze by her daughter and is said to be defensive about personal hygiene.
  • Velma herself is shown to have bad personal hygiene, frequently engaging in gross habits like eating out of trash cans and vacuum cleaners, refusing to go to the dentist, and peeing in the shower.
• Toad, as depicted in X-Men: Evolution, cheerfully and purposely amplified the base mankiness caused by his mutation. He showered on a monthly basis, ate insects, had an odour that caused other characters to open windows in his presence, and was described as having 'the personal hygiene of a dead pig'.
• Zeke's Pad: In "Clean Slate", Zeke turns his mother Ida, who is usually a Neat Freak, into her complete opposite. However, Ida takes her no-cleaning rules extremely strictly, and whoever is found doing a tiny bit of cleaning (e.g. moving a piece of paper to find something) is sent to the dreaded CR: the clutter room. The room is designed to break anyone of their cleaning habits.
