A yellow bunny with pink cheeks who inexplicably wears pink bunny slippers. His white fluffy curly hair tuft and cotton tail look exactly the same. His ears move to match how he feels. For example, if he's happy they'll stay up, and when he's sad they'll drop. Cuddles is one of the primary characters in the series. Like Giggles, Toothy and Lumpy, he appears in many of the advertisements. Cuddles was the second character to be created in Happy Tree Friends (the first being Shifty). Creator Rhode Montijo first drew him in a piece of paper with the phrase Resistance Is Futile above and that was how the creators got the idea for the show. His voice is even performed by the co-creator of the show Kenn Navarro.
Giggles is a pink chipmunk who has a white diamond-shaped marking, a white oval on her torso, and wears a big red bow on her head. She has the personality of a young girl, as she enjoys frolicking through flowers, having tea parties with her friends, ice skating, and having a shy and sweet demeanor. Her name comes from her habit of giggling often. She appears to be allergic to roses which was revealed in her Valentine Smoochie. Giggles is one of the primary characters who is just a lonely girl. She becomes Cuddles' girlfriend. She may have also been one of the first characters to be created along with Lifty and Shifty.
A light purple/mauve beaver with very large, gapped teeth (from which his name is derived), which appears to be diastema and freckles. Although his character description on the official site says he has "big ol' buckteeth" larger than the other characters, but in Season 2, he occasionally has the normal buckteeth. He is generally a very friendly character who likes to play around now and then, particularly with the younger characters. He admires Splendid (possibly when Splendid saved him in the episode Better Off Bread), and even dresses up as him for Halloween. He is good friends with Cuddles as seen in Spin Fun Knowin' Ya, Class Act, From A to Zoo, Remains to be Seen, Who's to Flame?, Take a Hike, Snow Place to Go, Blast from the Past, Can't Stop Coffin, Autopsy Turvy (Double Whammy Part 2), Party Animal, Concrete Solution, Wrath of Con, and Strain Kringle. He is also good friends with Giggles, Sniffles, Lumpy, and Petunia. Toothy is one of the primary characters in the show, as he appears in many commercials and advertisements.
He is a light blue moose with a very low I.Q., bad teeth (although they are clear white), distorted eyes and mismatched antlers (they always change directions). Known to be the big brother, or perhaps babysitter of many of the other villain. He usually means well but he's clumsy and extremely stupid. Furthermore, he screams like a girl. His usual catchphrase is "Mmm-hmm!" when he thinks he solved a problem or when he is satisfied.
An indigo and dark blue skunk with a sky blue arrow marking on her forehead, which is connected to the triangle shaped marking on her back and sky blue lines on her long tail who always wears a pink flower on top of her head and a pine scent car air freshener or deodorizer around her neck. Her name and species are somewhat a parody of the character Flower from the Disney movie, Bambi. She likes to play with dolls and strollers and also likes having tea parties.
Handy is an orange beaver with unexplained amputated arms (thus his name). The stumps are covered with bandages. He wears a tool belt and a yellow worker's helmet (the typical dress of most construction workers). He has mostly been portrayed as an adult but a couple of times he has been portrayed as a child such as in Happy Trails pt. 1 when he was on a school bus with many other characters and in Remains to be Seen when he and some other characters were dressed up and trick or treating on Halloween. His dam mostly consists of tools that are operated by hand.
A nerdy blue anteater who is one of the more intelligent characters in the series. He is the second character without a heart nose and a pair of buckteeth. He usually likes doing and reading science and math problems. To reinforce the 'nerd' image that Sniffles exudes, he is seen dressed up as a Star Trek character (probably Spock, the Vulcan ears being the giveaway) in Remains to be Seen and Something Fishy along with Mime , and also sports a pocket protector on his chest.
A light brown bear. He is another adult character. Some people refer to him as the stereotypically clueless, bathrobe-wearing, pipe-smoking 1950s style sitcom father. Pop only appeared without Cub in Something Fishy (excluding his BBQ smoochie, Milk Pong, and the end of Tunnel Vision), though Cub has appeared in multiple episodes without Pop. He was originally going to appear in Happy Trails Pt. 2: Jumping the Shark, but the creators considered it weird for Pop to kill Flaky. Instead Flippy took his place which explains why Flippy had Pop's voice. Though Pop is likely an adult character, he is not as large as other adult characters like Lumpy and Giggles' Mom.
Cub, as his name suggests, is a very young light brown bear cub, who is the son of Pop. He has the appearance and personality of a baby but the intelligence and mobility of a young child. He is the youngest and smallest character of the Happy Tree Friends and his eyes consist only of Pac-man pupils, giving him a more adorable appearance than the other characters.
A red porcupine whose quills are full of white flakes like dandruff, thus the name. Flaky is one of the most popular characters in the series and has the identifiable personality of being a very cautious and timid character, and as evidenced in Snow Place to Go, she may also have necrophobia (fear of death/dying) and possibly a fear of sharks. In Party Animal, she is shown to have a peanut allergy.
A blind lavender mole with dark sunglasses (or possibly teashades) with a mole by his nose. He wears a long purple turtleneck on his sweater. Like Mime and Cro-Marmot, he doesn't speak. This could be due to the upper part of his turtleneck covering his mouth, though more likely he is mute, seeing as he never makes a sound even through his most excruciating injuries or deaths. Though he is not deaf, he does seem to have hearing problems, as seen in Party Animal. Because disaster often follows his blind wandering, his actions and characteristics resemble those of Mr. Magoo. Despite being completely blind, he is often seen driving. He is also one of several characters without having known Pac-Man-shaped pupils (along with Lumpy, Nutty, Evil Flippy, and Cro-Marmot).
A golden bear with an orange afro and two sideburns who likes to dance to disco music (thus his name). He wears 1970s style clothing, including a yellow leisure jacket, yellow bell-bottom pants, and orange and white dancing platform shoes. His main catchphrase is "Oh yeah!". If he gets interested in anything, he will growl in a deep voice. He sometimes puts everyone around him into life-threatening trouble while dancing, but mistakes their movements of pain for funky dance moves. He is mostly seen either showing off or trying to impress the women, (though he kills them in progress) such as Giggles and Petunia and though sometimes flirts with Flaky. In Ski Ya, Wouldn't Wanna be Ya!, for example, he pushes Flaky out of the way as he enters the scene, then goes off to flirt with Giggles and Petunia. When Flaky is outside his door later in the episode, however, he seems to be happy to see her. In Rink Hijinks, he carelessly bumps Flaky into a floor buffer when he's trying to show off his roller skating skills.
Nutty is a light green squirrel with one yellow diamond shaped marking on his head and a large curled-up tail that moves when he's excited. Nutty has an addiction for candy or anything that is sugary. He has a big swirly lollipop, candy cane, small all-day sucker, and a candy apple stuck to his fur, which he even treats as his wardrobe, as evidenced in Chew Said a Mouthful, although this sometimes changes. In his debut in the episode Nuttin' Wrong with Candy, the candy attached to his fur fell off, therefore Nutty was seen without candy stuck to him for the first time.
A turquoise sea otter with typical pirate accessories like a Jolly Roger's hat, a striped red/white shirt, a hook, an eyepatch and two wooden peglegs. He enjoys fishing, sailing and eating seafood, one of his animal instincts, especially mussels, which was why he was named Russell. He also likes kite flying and even runs his own fast-food restaurant (in Mime to Five). His hook started off on his left hand, but later on, it is on the right hand for the rest of the series. Russell's initial design depicted him with a five o'clock shadow, though since his early appearances the creators got rid of it.
Lifty and his brother Shifty are two green kleptomaniac raccoons with dark green mask-like markings around their eyes. They frequently steal merchandise and produce from the other Happy Tree Friends (thus their names), as well as treasure hunting, ransacking houses or anything to get rich quick with the exception of Flaky, Lammy, Cro-Marmot, and Splendid. They mostly steal from Lumpy (in Meat Me for Lunch they stole meat from Lumpy's deli mart, in Milkin' It they stole a cow from Lumpy's farm, in Concrete Solution they stole his wallet, and in Junk in the Trunk they abducted his pet elephant). They probably rob Lumpy so frequently because his lack of intelligence and common sense makes him an easy target.
A purple male deer with sharp ears, antlers on top and who wears face makeup and a navy blue/dark purple and white, striped shirt. He never speaks, because he is a mime, causing others to have a hard time understanding him. Apparently, most of his possessions are imaginary yet can be stolen (or even shown to be real), as evidenced in Easy For You to Sleigh, Mime to Five, Concrete Solution, Keepin' it Reel, and I Heart U. Sometimes the things around him are imaginary, such as walls in Dunce Upon a Time, which he uses in the name of showmanship. He has even done some seemingly impossible things, such as making an audible honking sound while riding a unicycle in Concrete Solution and making noises while interacting with his 'imaginary' furniture. It was once said that he's mute, but in some episodes, like in Happy Trails pt. 1, Out of Sight, Out of Mime, Something Fishy, Keepin' It Reel, and I Heart U he has made audible noises (e.g., choking noises, snoring, or blowing noises) making it evident that he can speak, he just chooses not to (although he has been known to not scream even when in severe pain as seen in Double Whammy Part 1 when his insides were set on fire). This has led to other characters' deaths, such as in Who's to Flame? when his choosing not to talk to Lumpy, a fireman, over the phone eventually led to the destruction of the entire town.
Cro-Marmot is a prehistoric greenish-yellow marmot frozen in a block of ice who wears leopard skin loincloth and holds a wooden club in his hand. He appears to be greenish-yellow due to the ice's hue that blends in with his natural color. He is somehow able to perform many tasks offscreen while entirely encased in ice, such as throwing snowballs, somewhat akin to how Handy can perform construction and other tasks without any visible hands. To keep himself frozen, Cro-Marmot stays mainly in cold areas, and sometimes drives an ice cream truck. He lives in a giant snow globe, or rather a small igloo inside a giant snow globe. His hobbies include serving people ice cream, snowboarding, and surfing. He rarely dies in the series, the reason being that the ice he's usually encased in serves as a protection from disaster, thereby rendering him almost invulnerable to most unfortunate events. Also, most of his "deaths" are debatable. When they aren't, they involve a form of heat, disasters (such as explosions or collapsing bridges) or being eaten.
Flippy is one of the main characters in the Happy Tree Friends series. He has been liked by many fans over the years and he is often the base for HTF fanart, fanfictions, and fan characters. Because of this he is considered to be the most popular character in the series.
A pale blue superhero flying squirrel with light blue patagiums (gliding wings), a light blue/white oval marking on his torso, and a red mask around his head. He is largely based on Superman; he can fly, shoot laser beams from his eyes, has super strength, super speed, supersonic hearing, can turn back time, and can breathe ice. He is often seen doing housework until he hears the screams of a character that needs to be rescued. His appearance is somewhat based on Rocky J. Squirrel from Rocky and Bullwinkle. Similar to Flippy, Splendid isn't featured in either the TV or internet series a lot due to his repetitive trend of killing the characters he rescues. Whenever he appears, he is the character the episode revolves around with the exception of Class Act, and it is unknown why that is.
As seen in his debut episode, A Bit of a Pickle, he is one of the characters, to kill other Happy Tree Friends on purpose (debatable, since he's imaginary). He seems to like tea parties, and was seen having one with Lammy in the begining of A Bit of a Pickle.
A Mayan statue which brings death and bad luck. It does nothing else than just sit there while bringing death and bad luck. When it appears, everyone who is near the statue dies brutally. This idol is based on the golden fertility idol in Raiders of the Lost Ark. It features in the episodes "Treasure These Idol Moments", "Hello Dolly", and "Idol Curiosity". It appears as a prop in many other episodes such as "Crazy Antics", "Happy Trails pt. 1", "Milkin' It", "Class Act", "Ipso Fatso", "Who's to Flame?" and "Every Litter Bit Hurts".
Whenever they appear in an episode, it often involves Sniffles trying to eat them, only for him to be tortured and killed by the Ants in the most sadistic manners. They are voiced by Kenn Navarro, Warren Graff and Ken Pontac.
He has appeared only as a villain in the episode "Mole in the City". He appears to be the arch-enemy of the Mole, seeing as they are both involved in industrial espionage. He was killed by explosives that the Mole planted in a briefcase. His death may have been permanent.
Splendont is a rival super hero of Splendid. He was trapped in a mirror floating in space that broke when a rock went up and hit it. He is likely to return in future Splendid's SSSSSuper Squad episodes.
Used en masse when needed, for example, in a large audience. They are also occasionally killed en masse. Some of them look like a darker version of Toothy without a tail, though they resembled a variety of animals in some of the earlier episodes.
Appearing for the first time in the episode Helping Helps. After she thought Giggles was killed by a tidal wave, she was just horrified, but was cheered when Splendid delivered Giggles to her (but she had no idea that Giggles was dead, or had an acorn for a head). She is one of the few characters who is as tall as Lumpy. She is voiced by Dana Belben.
A special character that starred in his own special episodes. The first episode was "Books of Fury", and he was featured a second time in "Enter the Garden". If you watch closely on Blind Date, the movie being played is "Books of Fury", in "Rink Hijinks" there was a picture of him on a crane machine, and in "Keepin' it Reel" he was on a movie screen once again. He is the only star-character that hasn't died. Buddhist Monkey has undertaken more adventures in the spin-off Happy Tree Friends Action series: Ka-Pow!
Mouse Ka-Boom is a mouse who is also on Flippy's side. He specializes in explosives and his ears appear to be wrapped in bandages due to hearing loss caused by series of explosions. He is French as evidenced by his appearance and the fact he usually says "Le (something)."
