Main Characters

"Caring and sharing is cause for charming cheers!"
Voiced by: Kenn Navarro

A cute yellow rabbit who has pink cheeks and is always wearing pink bunny slippers. Cuddles is the main character of the series more so than anyone else, and is one of the four "original" Tree Friends. Despite his cute nature, he has been shown to be a bit of a rebellious Tree Friend who enjoys skateboarding, snowball fights, and daredevil acts. He was the second Tree Friend created (Shifty was the first Tree Friend created), appears in most advertisements, and to date holds the highest death count in the series.

  • And I Must Scream: Can't Stop Coffin' just can't give poor Cuddles a break. His screaming inside of the titular coffin is drowned out by multitudes of distractions and loud noises. This leads to him clawing his fingers to the bone trying to scratch his way out, almost burning to death before being "saved" by water entering the coffin and proceeding to almost drown him, to being saved from that by a car breaking through the coffin and having one of its wheels grind down on his face, all while being unable to do anything about it. This doesn't even kill him, as at the very end of the episode he tries to crawl away from the coffin after it opens, moaning in pain before the aforementioned car ends up crushing him to death.
  • Blush Sticker: Permanent ones, too.
  • Bunnies for Cuteness: He's a rabbit, and an adorable one too.
  • Buried Alive: In Can't Stop Coffin. He doesn't stay alive for long, however.
  • Butt Monkey: Besides Handy, he has the highest death rate out of all the characters.
  • Crazy Jealous Guy: He gets really upset in "Youtube Subscriptions: 101" when he thought Giggles was dating Disco Bear.
  • Creator Cameo: One of the creators voices him.
  • Expressive Ears: His ears droop when he's upset.
  • Hair of Gold, Heart of Gold: Has yellow fur, and is very friendly.
  • Helium Speech: In From A to Zoo. Later on, his eye is impaled on the nozzle and his screams become higher and higher in pitch before he finally dies.
  • Ironic Name: His name is "Cuddles" but he's actually a daredevil who's quite fond of risky sports, and being naturally mischievous to boot.
  • Interspecies Romance: He's together with Giggles in most episodes, who's a chipmunk.
  • Jerk with a Heart of Gold: Cuddles can be a little self-centered and inconsiderate at times, such as pushing Flaky down a water slide against her will.note  But otherwise, he's very kind toward others.
  • Keet: Very outgoing.
  • Only Sane Man: The very rare chance that Flaky isn't playing this role, it's him.
  • Pink Girl, Blue Boy: Inverted - his favorite color is pink.
  • Real Men Wear Pink: Pink bunny slippers, to be exact.
  • Screams Like a Little Girl:
    • As his eye gets impaled on the helium-nozzle in "From A To Zoo" as a result of inhaling the helium.
    • He has a somewhat high-pitched voice in general, but it's especially obvious when he screams.
  • Screwy Squirrel: In From A to Zoo.
  • Sensitive Guy and Manly Man: The Manly Man to Toothy's Sensitive Guy.
  • Series Mascot: Cuddles is most prominently used to advertise the show. He usually appears solo in promotional art.
  • Stalker with a Crush: In "Youtube Subscriptions: 101" he apparently stalks Giggles over the internet.
  • Too Dumb to Live: In "Water You Wading For", when he jumps in a waterhole that has a no-swim sign.
    • Of course, it's possible that he didn't see the sign. However, he definitely plays it straight in From A to Zoo. Don't poke a baboon (or a rhinoceros).
  • Turbine Blender: In Spin Fun Knowing Ya, and againnote  in Blast from the Past. And while it isn't a literal turbine this time around, he suffers a similar fate in Party Animal.
  • Yandere: He is one to Giggles, if "Youtube 101: Subscriptions" is anything to go by.

A friendly pink chipmunk who wears a red hair bow. Giggles is one of the four "original" Tree Friends and is most often played as a girly girl, along with Petunia (with whom she is best friends). She also cares strongly for the environment, and will lose her cute nature when she sees someone littering or polluting. Despite being the one most often paired with other Tree Friends for Valentine's Day episodes, she and Cuddles are seen as the "default pairing" of the series.

"Using a toothbrush is tantamount for twinkling teeth."
Voiced by: Warren Graff

An unlucky purple beaver named for his large, gapped buckteeth. Toothy is one of the four "original" Tree Friends and is most often played as the everyman. The creators of the show feel he doesn't have enough of a personality, and plan to bring him out of his shell in later episodes. His trademark injuries have to do with his eyes, mostly as shout outs to his most famous episode, Eye Candy.

  • Bee Afraid: So far, he's been attacked by bees a total of three times, twice of which resulted in a bee sting to the eye.
  • Butt Monkey: Most of the time, due to his many painful eye injuries and low survival rate.
  • Depraved Dentist: To Nutty in "Nuttin' But the Tooth"; was a drill THAT necessary for a toothache?
  • Hidden Depths: As revealed in "Read 'em and Weep" he apparently owned the Necronomicon before selling it to Pop.
    • He shows interest in gardening in the episode "An Inconvenient Tooth"
  • The Everyman: Has barely any character traits besides his haplessness.
  • Eye Scream: His trademark injury/death since Eye Candy.
  • Only Sane Man: The very rare chance that Flaky (and Cuddles, sometimes) isn't playing this role, it's him.
  • Sensitive Guy and Manly Man: The Sensitive Guy to Cuddles' Manly Man.
  • The Tooth Hurts:
    • The entirety of "An Inconvenient Tooth" is all about Toothy's teeth over growing and him struggling to break them off.
    • Breaks a tooth after biting on a bean can in "Snow Place To Go".
  • Unlucky Everydude: He has a very low survival rate, and is also The Everyman.
  • Youthful Freckles: Has freckles on his cheek.

"For a lazy lunch, try leftover loaf!"
Voiced by: David Winn

An idiotic blue moose whose lack of intelligence often lands himself and others into trouble while driving the plot for many episodes. Lumpy is one of the four "original" Tree Friends and to date has the official highest kill count and starring count in the series. Despite his stupidity, he often holds high ranking jobs (such as a doctor), and is sometimes placed with the care of the smaller Tree Friends. He shows signs of greed as well, as visited in several episodes.

  • Asshole Victim: When portrayed as a villain.
  • Ax-Crazy: In the pilot episode, he kills Giggles, Cuddles, and Toothy just because they laughed at him.
  • Big Brother Instinct: When the smaller Tree Friends are in his care, he'll go to great lengths to try and protect them - even if he usually winds up killing them or himself in the process.
  • The Big Guy: He is the tallest of the Tree Friends.
  • Blue Is Heroic: Lumpy is a blue and well-intened moose.
  • Catch Phrase: "Mm-hmm."
  • Crouching Moron, Hidden Badass: Lumpy and Fliqpy have fought two times in the series and in both of them, Lumpy actually wins!
    • He also manages to take down a squid the size of a small house with a mouse trap!
    • And Wipe Out reveals he's a pro surfer, even managing to juggle chainsaws while hanging ten!
    • He climbs a rope with a freshly paralyzed back in Take a Hike, and the rescue he (almost) pulls off at the end of The Wrong Side of the Tracks also counts.
  • Cruel and Unusual Death: Along with Sniffles, he suffers some of the worst deaths.
  • Dirty Coward: In Wingin' It, Lumpy uses many electronic devices in a passenger jet in flight, disrupting its navigational systems. When the plane starts to malfunction, Lumpy kicks out the plane's door, sucking several characters to their inevitable deaths, and takes all of the parachutes for himself, forgetting to properly put on even one.
  • Disproportionate Retribution: He, along with Flippy, Handy, and Sniffles, kills Flaky, just because she popped the raft with her quills in "Happy Trails Part 2".
  • The Ditz: Lumpy's stupidity is the driving force behind the plots of many episodes.
  • Expy: Of Bullwinkle, to the point that the creators had to invert the direction of his antlers to keep him from looking too much like Bullwinkle.
    • And he sounds a little like Goofy if you think about it...
  • Gentle Giant: The tallest Tree Friend and is also pretty nice.
  • Jackass Genie: Unintentionally in As You Wish.
  • Karmic Death: A large portion of Lumpy's deaths relate to him doing something thoughtless, usually while on the job.
    • In Concrete Solution, Lumpy hides the fact he accidentally killed Handy by hiding him in the cement they were pouring. Later he's crushed by the block of cement with Handy's corpse pressed in it.
  • Lethal Klutz: His stupidity has caused so many deaths that he has an official kill count higher than that of even Evil Flippy/Fliqpy. In fact, he hold the highest official kill count in the series...mostly due to his stupidity.
  • Lethally Stupid: Trope Codifier. His stupidity caused sooooooo many deaths. The creators said the reason Lumpy has so many different jobs is because his incompetence causes havok wherever he goes, and gives different situations.
  • Life-or-Limb Decision: In Out on a Limb.
  • Literal Genie: In As You Wish, where he plays a genie in a (table) lamp. His wishes cause grave injuries or death to the other characters.
  • Made of Iron: Despite being the most unintelligent Tree Friend in the cast, he is the one who survives the most - a more common occurrence is "Too Dumb For Those Around Him To Live". It seems to have a reason - he is the tallest and probably strongest of the cast excluding Splendid, so the times he doesn't die immediately, he often gets injured. In the TV season, he has survived falling off a highway overpass onto the road below and then getting run over by Lifty and Shifty's van (Concrete Solution) and getting hit head-on by a truck and getting entangled in a bicycle (A Change of Heart).
  • Moose Are Idiots: Probably the most glaring example.
  • Nice Guy: In most of his appearances, he's usually a well-intended guy.
  • Non-Standard Character Design: Not only does Lumpy tower over the other Tree Friends, he also lacks the round faces that every other character has. He looks the most like the animal he is, compared to the other Tree Friends. He is also one of the few characters (along with Sniffles) who does not have a heart nose.
  • Odd Friendship: With Russell in the earlier seasons.
  • Out-of-Character Moment: He plays the villain in We're Scrooged!, killing Toothy in order to sell his body parts for profit. In the TV episode Dunce Upon a Time, which is a Whole Plot Reference to Jack and the Beanstalk, Lumpy takes on the role of the lumbering giant of the castle in the sky, killing the other characters to make his meal and when they try to escape.
    • There are times when Lumpy has bursts of intelligence, which goes against his usual The Ditz portrayals.
      • In Doggone It, he was the only one to realize the reason for Whistle's attacks.
      • In A Sight for Sore Eyes, he realized the danger The Mole's blindness poses to everyone and gave him a guide dog to replace his cane.
      • In We're Scrooged!, he quickly managed to make a paddle with his own eye to prevent Sniffles from leaving the shop.
      • So far he is the only one to be aware of the causes of Flippy's PTSD, since in Without a Hitch and Random Acts of Silence, several characters who appear to be aware of Flippy's PTSD tought that he would flip out randomly, while in Double Whammy Part 1 he figured out the cause of his problem and attemped to cure it.
      • He managed to finish the bridge in Concrete Solution despite his coworkers being dead.
      • In A Change of Heart, he managed to save Disco Bear's life by giving him a heart transplant...with an orca's heart.
  • Precision F-Strike: He has a tendency to say "What the hell?" when something goes wrong, except for in Doggone It, where it's this.
  • Screams Like a Little Girl: Lumpy speaks with a deep voice, but in his death throes and instances of torture, he has a high-pitched scream.
  • Smart Ball: How Lumpy defeats Evil Flippy and the zombies in "Remains to be Seen".
    • He also managed to outsmart Fliqpy again in the episode "By The Seat of Your Pants"
  • Too Dumb to Live: Inverted most of the time (an exception being the episode The Chokes On You).
  • Temporarily a Villain:
    • In "Dunce Upon a Time", where he is a giant who eats people.
    • In "We're Scrooged", he lets Toothy die so he can sell his body parts.

"Plant plenty of pretty, perfumed, purple and pink flowers!"
Voiced by: Lori Jee

A sweet blue skunk who wears a flower on her head and a pine tree car freshener around her neck. Petunia suffers from Obsessive Compulsive Disorder and is quite a neat freak. She is best friends with Giggles and they like to hang around with each other, have tea parties, play with dolls, etc. She tends to die the messier deaths in the series, such as having her face pressed to a grill or getting pulled through a sink. For a long time, she was the only character not to have killed another Tree Friend—until she started a cooking fire in "Who's to Flame?"

"Science is seriously satisfying!"
Voiced by: Liz Stewart

A nerdy blue anteater with glasses and a pocket protector. Often seen as the brains of the show, Sniffles is a geek who loves science, inventing, Star Trek, and superheroes (Splendid especially). He sometimes delves into mad scientist territory on a few occasions, however. There are several episodes dedicated to him and a family of ants who he always tries to eat, though the ants always end up killing him in the end.

    The Mole 
"Myopic, meandering marches most often lead to macabre mishaps."
Voiced by: Dean MacDonald

A blind lavender mole who wears sunglasses and a dark turtle neck sweater, with a mole on his face. His blindness drives the plot for many episodes, since the creators feel that he and Lumpy are the most inept Tree Friends for any given job. Paired with his blindness is also the inability to speak, possibly because of his sweater. His deaths are limited to the TV series because a producer for the internet seasons has a blind daughter. A lone Ka-pow! episode, Mole in the Big City, visits the idea that The Mole is an international spy, an actual character trait that was cut before he was introduced into the series.

  • A Dog Named "Dog": A mole named "Mole".
  • Beauty Mark: Has one near his nose.
  • Behind the Black: Whenever he eats.
  • Blind Mistake: His biggest form of comedy. He has a tendency to mistake gruesome objects for more commonplace ones.
  • The Faceless: His turtleneck sweater covers his mouth all the time.
  • No Mouth: His mouth is covered by his sweater.
  • Nice Guy: Apparently, seeing as how he was willing to take his date to many nice areas in "Blind Date", and in "Out Of Sight Out Of Mime", he gives trick or treaters a lot of candy. In another episode, he tries to get a baby bird back in the tree. He also likes to help others regularly, though he does sometimes cause them problems.
  • Half-Dressed Cartoon Animal: No pants.
  • Handicapped Badass: As seen in Mole in the Big City.
  • I Ate WHAT?!?: He's the most frequent character to mistake body parts for food/produce, due to his blindness. He never seems to notice this.
  • Running Gag: The Mole is seen driving in almost every episode that he appears in season four.
  • The Stoic: Shows no emotion whatsoever, no matter what the situation. Justified, as he is blind, so he can't really see what's exciting, depressing, or scary.
  • The Speechless: He's never said a single word in any of his appearances.
  • Spell My Name with a "The": The only character to have the word "the" as part of his name.
  • Sunglasses at Night: Possibly justified by the fact that he's blind. A trivia card mentions he has unseen blue eyes, though.
  • Too Dumb to Live: Like Lumpy, a more common occurrence being "Too Dumb For Those Around Him To Live"(exceptions being Who's to Flame? and A Sight For Sore Eyes).

"Parental parents are patient and proud."
Voiced by: Aubrey Ankrum

A bumbling tan bear who is almost always seen with a pipe and wears a red hat and robe. Pop is a single father to his son, Cub, whom he tends to accidentally kill on a regular basis due to his oblivious and slightly dim nature. Despite this, he is actually very caring towards his son and will go out of his way to save him in the few times he knows Cub is hurt or lost. His wife/Cub's mother is dead, as was confirmed in a tweet by Ken Navarro.

  • Beary Friendly: He isn't shown interacting with characters other than Cub often, but when he does he is shown to be a good-natured sort.
  • Bumbling Dad: His obliviousness to his son's safety often leads to the latter's often gruesome death.
  • The Determinator: The few times he ever is aware that Cub is in danger he'll never stop in trying to save his son, up to and including going over a waterfall in And the Kitchen Sink and successfully fending off a rabid dog in Doggone it!
  • Eye Scream: One of his deaths in Pop's BBQ Smoochie is him being impaled through the eye and the back of his head with a kabod stick.
  • Helicopter Blender: His first death (Having a Ball) has him on the bad end of falling on top of moving helicopter blades.
  • Half-Dressed Cartoon Animal: His robe and hat.
  • Papa Wolf: See The Determinator. In a less extreme example, he becomes unusually confrontational when Nutty steals Cub's lollipop in A Sucker for Love.
  • Parental Obliviousness: How clueless he is to trouble Cub gets into usually causes the latter's deaths.
  • Smoking Is Cool: Has a pipe in his mouth most of the time.

"Cute kids are cuddly and carefree!"
Voiced by: Lori Jee

An adorable tan baby bear, who is always wearing a propeller beanie hat and a diaper/nappy. Cub is Pop's son, and often his deaths are due to his father's oblivious nature. He tends to act stereotypically baby-like (babbling, drooling, etc.), though he has the mobility of a toddler. Because of his babyish nature and innocence, he doesn't usually notice if someone has died or is in pain, and has even played with severed body parts on occasion.

  • Baby Talk: Being a baby, this is how Cub talks.
  • Butt Monkey: Dies in most of his appearances, usually caused by his father by accident. Unlike most of the characters, he has barely any way to protect himself due to just being a baby.
  • Demonic Possession: In Read 'Em And Weep, by an Eldritch Abomination.
  • Dead Baby Comedy: All of his deaths.
  • Disney Death: In And the Kitchen Sink when Pop sees Cub's seemingly decapitated head lying in the sand after the two have gone over a waterfall. When he grabs his head, he finds that he was just buried in the sand up to the neck, and Cub lets out a weak cough.
  • Fearless Infant: Sometimes, he is happy even in dangerous situations.
  • Humongous Mecha: In Cubtron Z.
  • Infant Immortality: His entire existence in the show revolves around averting this.
  • Made of Iron: In And the Kitchen Sink, Cub survived being scalded by extremely hot water, having his entire lower half of his body disintegrated in a sink garbage disposal, being pulled by the neck with a rope tied to a station wagon whose accelerator Pop floored (in an attempt to free Cub from the sink drain), being dragged by said station wagon while still stuck in the sink, and falling off a waterfall. These injuries and situations usually kill or dismember the older Tree Friends. He only died by drowning in the bathtub when Pop was looking away.
  • Missing Mom: His mother's absence is never explained.

Voiced by: Nica Lorber

A nervous, cowardly red porcupine whose quills are full of dandruff. Flaky is the subject of a long-standing gender dispute, though most of the creators and fans refer to her as a female. Her official gender description on the website is a question mark. She is very cautious, scared of nearly everything, and is prone to motion sickness. Despite this, she can be very brave if the situation calls for it. Is also allergic to peanuts, as shown in "Party Animal".

On April 28, 2012, on the Twitter for Happy Tree Friends, in reply to someone's tweet, it was an actual discussion about Flaky's gender and they intentionally stated Flaky was a girl, confirming Flaky's gender.

  • Action Girl: She manages to land a runaway plane BY HERSELF in Wingin' It.
  • Adorkable: She is a shy, awkward character.
  • Ambiguous Gender: Word of God (usually) says girl. Word of God also likes trolling the fanbase, as seen in Something Fishy., when she couldn't decide whether to go into the men's or women's restroom, where her unknown gender is actually lampshaded. (In the end, she went into the women's restroom, which proved disastrous, because the plumbing was infested by Russell's deadly piranha fish.)
  • Beware the Nice Ones: She is one of the more caring characters of the series, sometimes even going against her fears to help someone or throw a surprise party for a Serial Killer (granted, he's only like that when he is reminded of the war). That said, Without a Hitch has her causing another character harm intentionally, and leading to their death because of her paranoia alone.
  • Companion Cube: A garden gnome she finds in a box in Snow Place to Go, after being stranded along with Lumpy, Russell, Cuddles, Giggles and Toothy. She starts to have a rather creepy, if oddly affectionate and motherly, attitude towards it during her Sanity Slippage right before her death.
  • Cowardly Lion: When she isn't simply cowardly.
  • Flanderization: Flaky starts off somewhat cautious in season 1. She only got scared of things that were truly dangerous. By season 2, she starts to develop fears that were somewhat irrational (i.e. skating, flying, and skiing). By the end of season 2, she's pretty much scared of anything that's nearby her (i.e. chicks). It's starts to tone down in the TV series, when she was seen brave enough to throw a birthday party for Flippy and bring a baby bird back to its nest. However, by season 3, she's pretty much scared over anything (i.e. going in the wrong bathroom).
  • Grievous Harm with a Body: She's used as a club by Fliqpy to kill Cuddles with in Keeping It Reel. Considering her quills... ouch.
  • High-Pressure Blood: When she bleeds out of her eye in one of her Smoochies.
  • Idiot Ball: See Too Dumb to Live and Out-of-Character Moment.
  • Karmic Death: She dies when her airbag dislodges in Without a Hitch after murdering a non-flipped out Flippy.
  • Lovable Coward: She is understandably always scared of everything, but her whimpering, stuttering and crying is the cutest thing you'll ever see on the show. Not to mention the moments she is actually happy.
  • Nice Girl: Usually caring and nice towards everyone.
  • Odd Friendship: Nutty was the one who was helping her out with her surprise birthday party in Party Animal. The birthday party was for Flippy, which is even more odd considering she should probably be afraid of him.
  • Only Sane Man: When living in a world where you can die by falling down the stairs, getting hit by a coconut in the head or being split in half by a stump she has every damn right to be freaked out of her mind.
  • Out-of-Character Moment: In "Lesser Of Two Evils". Let's see... she throws a party, when she usually never takes the initiative to do anything. She almost never looks scared in the episode, except for a few moments. Guess who the party is for? FLIPPY. Yes, Flippy. The character she's deadly scared of. Usually she knows better than do such a thing.
  • Plot Allergy: Peanuts, as shown in "Party Animal".
  • Prickly Porcupine: She's the only porcupine on the show. Type B almost describes her perfectly, as she is certainly a Woobie and very shy, but she isn't shunned for her quills which normally don't get in the way unless death is involved.
  • Properly Paranoid: Considering what usually ends up happening after attempts at even the safest actions, Flaky's fears seem considerably less unreasonable.
  • Red Is Heroic: A caring porcupine, and has red fur.
  • Sanity Slippage: Without A Hitch, where she kills Flippy thinking he was going to kill her. She also loses her mind in Snow Place to Go momentarily.
  • Ship Tease: Taking the show's standards into account, she is this with Flippy, particluarly Lesser of Two Evils on both parts, Without A Hitch on Flippy's part and Random Acts Of Silence on Flippy's part, again.
  • Spike Shooter: Averted, despite the myth about porcupines shooting their quills. Though there has been occasions where her quills had been launched by something else. In Rink Hijinks, for example, she is sucked into a floor waxer and slowly shredded. As she was being spun around her quills start to get launched everywhere, with a good chunk of them going straight into Disco Bear.
  • Tertiary Sexual Characteristics: Averted - Possibly what leads to the high amount of Viewer Gender Confusion.
  • Threatening Shark: She's been attacked by sharks three times over the course of the series: In Wipe Out, Happy Trails Pt. 2, and Wingin' It. Interestingly, she's survived all three of these attacks, only to die to something else.
  • Tomboy And Girly Girl: The tomboy to either Giggles'/Petunia's/Lammy's girly girl.
  • Too Dumb to Live: In rare occasions, seeing how she is the Only Sane Man of the show. However, she did play this straight in Happy Trails Part 2: Jumping the Shark, when she sat on an inflatable raft that Lifty and Shifty inflated. Because her quills touched the raft, it sank and ended up leading to Lifty's, Shifty's, and her own deaths.
    • Also happens in Wingin' It, when she finally lands the abandoned plane. She attempts to slide down the emergency inflatable slide, only for it to pop, due to her quills.
  • Vomit Discretion Shot: In ''Wingin' It', where the sight of a plane makes her double over and puke just offscreen. The puddle is seen in the next shot, though.
  • Why Did It Have to Be Snakes?: Flaky has an odd fear of baby chicks, more so than everything else. Guess what she encounters in the petting zoo in A To Zoo. Weirdly enough, it seems to be just chicks. She doesn't appear to be particularly afraid of any other birds.

"Nuttin' wrong with going nuts for nectarously nice candy!"
Voiced by: Michael "Lippy" Lipman

A hyperactive green squirrel who always has several pieces of candy stuck in his fur. Nutty is absolutely addicted to candy or anything sugary, and will sometimes add pounds of sugar to something just to make it sweet enough for him. His constantly-dilated eyes are mismatched with one lazy eye (a side effect from his high sugar consumption), and his vocabulary consists almost entirely of laughing and giggling. His sugar addiction has gotten him in trouble more than a few times.

  • And I Must Scream: In "Dunce Upon a Time", Nutty eats beans, which start to grow into a giant beanstalk in the night out of his body painfully. At the end of the episode, it shows that he was still alive before Giggles kills him with an axe so Lumpy couldn't reach the ground.
  • Asshole Victim: Depending on the episode. He's not always a Jerkass to others, but when he is, expect him to die in the end.
  • Ax-Crazy: Not to Flippy's level, but he still has his moments. Do not come between him and his candy or games, as proven in False Alarm.
  • Beware the Silly Ones: Non-villainous example. Nutty is not always taken seriously by the other Tree Friends due to his sugar addiction. There are, however, multiple times where he has killed another character deliberately.
  • Braces of Orthodontic Overkill: In Chew Said a Mouthful, he gets them to hold his jaw together after breaking it on a gobstopper.
  • Butt Monkey: Not including episodes where it was never confirmed if he survived or not, Nutty has survived a whopping total of 11 episodes in the 44 that he appears in.
  • Big Eater: Has a huge appetite, mainly towards sugar.
  • Companion Cube: A Sucker For Love was almost entirely dedicated to his fantasies of various candies... as girlfriends and wives. Also doubles as a Cargo Ship.
  • Determinator: Even when he's dying, he'll always try to get loads of candy.
  • The Ditz: As a result of his candy addiction, he's not the sharpest knife in the drawer. See Too Dumb to Live below.
  • Dissonant Laughter: He sometimes laughs while he dies.
  • Extreme Omnivore: He'll eat anything that vaguely resembles candy, from Christmas lights to cement mix and even other characters in costume.
  • Flanderization: From just a sugar addict to pretty much falling in love with candy.
  • Green and Mean: Can be pretty selfish, and is green.
  • G-Rated Drug: Consuming anything sugary, sometimes in tiny amounts, will send Nutty bouncing off the walls. Prolonged periods without sugar will send Nutty into withdrawal symptoms, becoming irritable and mentally imbalanced.
  • Groin Attack: He takes a yo-yo to the crotch in one of the options in Nutty's Party Smoochie, grinding it against his groin so hard that he combusts!
  • Hidden Depths:
    • In one episode he was playing checkers against Sniffles - and was winning. Not something expected from the off-the-walls Sweet Tooth squirrel, especially not against the resident Smart Guy. Though, considering it's Happy Tree Friends, their game never gets finished.
    • If you discount the fact that it's directed towards candy, his Imagine Spots in A Sucker for Love shows him being much more romantic than you'd expect from his normal personality, bringing his "wife" breakfast in bed and even imagining having children. Also, he has a serious jealous side.
  • Jerkass: He will prioritize his insatiable sugar addiction over the lives of others and even of himself.
  • Keet: Highly hyperactive; it must be because of his sugar intake.
  • Laughing Mad: Always. Always. Even when in pain, suffering, or dying he will intersperse giggling with groaning and screaming.
  • Meaningful Name: His name says it all — he's as nutty as a squirrel's breakfast..
  • Mismatched Eyes: One eye is black, the other is lazy and colored green.
  • Papa Wolf: He does something to Lumpy in Sucker for Love after the latter eats his chocolate-children to wind himself up in jail. Turned out it was all a day dream, but it's still Nutty's dream, after all.
  • The Sociopath: Their are times were Nutty will endanger the lives of, not only himself, but the people around him as well, and he doesn't seem to care when his actions get them killed.
  • Skewed Priorities: Even in times of duress, he will go back to get candy. It often results in his deaths.
  • Sweet Tooth: A whole mouthful and then some.
  • Take a Third Option: Not by intention, but Nutty has a habit of becoming addicted to various sources. As seen in False Alarm, he has an adoptive personality. In said episode, Nutty goes into a habit of playing games shortly after a successful withdrawal from candy. Also, he gets his old habit back after eating a lollipop upon outside of a source of gaming.
  • Too Dumb to Live: Many of his deaths could have been avoided if he would learn to prioritize his own well-being over a handful of candy.
    • In Chew Said a Mouthful he bites on a jawbreaker and ends up breaking his jaw three times.
    • In A Sucker for Love, he scoops up some glass shards and gum balls from a broken gumball machine and shovels them all into his mouth. When he blows a bubble, it pops and the glass shards impale his face.
    • In As You Wish, he wishes for a lollipop, tries swallowing the entire thing whole, and promptly chokes to death.
  • Trademark Favorite Food: Anything sugary.
  • Villain Protagonist: In A Sucker for Love, he tries to steal a lollipop from Cub.

"A happy home has all the right hardware for any happenstance!"
Voiced by: Warren Graff

A helpful orange beaver with amputated hands, who is always seen wearing a hard hat, a tool belt, and arm-nub bandages. Despite his handicap, Handy is most often seen doing (or at least attempting) activities that require hands. Ironically, his dam is full of things that are handheld. Whenever he fails at a task or remembers he doesn't have hands, he will pull his trademark look of a frustrated glance into the camera.

  • Aside Glance: Once he realizes he does not have hands or tries to do something that requires hands, he will glare into the camera.
  • Badly Battered Babysitter: In "A Handy Nanny".
  • Behind the Black: Whenever he successfully does something that requires hands, it's almost always done off-camera.
  • Breaking the Fourth Wall: Whenever he gets frustrated over his lack of hands, he turns to the camera and snarls.
  • Butt Monkey: A recurring joke is that his lack of hands prevent him from doing certain things, followed by his signature growl of frustration when realizing that said things need hands to be done. There's also the fact that he has one of the lowest survival rate in the series. Take, for example, "Change in Heart" where he is the only character that dies in the episode.
  • Death Glare: Often makes this face when he can't do something because of being without hands.
  • Disproportionate Retribution: He, along with Flippy, Lumpy, and Sniffles, kills Flaky, just because she popped the raft with her quills.
  • Distressed Dude: In See What Develops, he was literally hanging by a thread (with his mouth) while Splendid was deciding whether he should rescue him or stop The Mole.
  • Grievous Bottley Harm: In Spare Me, he's hit in the back of the head while drinking soda from a bottle, which causes it to get stuck in his eyesocket while his eye rattles around inside the bottle.
  • Handicapped Badass: Why yes, he did build an entire house by himself. Twice.
  • Helicopter Blender: In Who's to Flame?, after pushing an unexplained eject button on his helicopter.
  • Ironic Name: A beaver named Handy who lacks hands.
  • Interspecies Romance: With Petunia, who's a skunk.
  • Lack of Empathy: The episode "The Wrong Side of the Tracks" and "Ipso Fatso" shows that he rarely ever feels sympathy or grief when other characters die or get injured (with a few exceptions being The Mole and Petunia). He suffers a Karmic Death in both episodes.
  • Mr Fix It: He is portrayed as a construction worker...without hands. Yet he manages to perform tasks that require them, including building an entire house. We just do not see him actually do it.
  • Nice Hat: Wears a hard hat. It has protected him from serious injury and death on a few occasions.
  • Nonindicative Name: His name is Handy, but he has no hands.
  • Official Couple: With Petunia.
  • Silent Snarker: Would easily be the most fit to say something sarcastic if he could.

Voiced by: Sarah Castelblanco

A quiet purple deer (he is actually capable of speech like the others, just choosing rather to be silent) who is (as his name suggests) a mime, complete with face-paint and a striped shirt. Mime is very talented at various circus and carnival acts, such as pantomiming, juggling, making balloon animals, fire breathing, and riding unicycles. His reluctance to speak often lands himself and others into trouble, and he will sometimes choose showmanship over actual helpfulness.

  • Blush Sticker: As part of his mime getup.
  • The Casanova: In Easy Comb, Easy Go.
  • Cute Mute: He never says anything, and is a cute deer.
  • Demoted to Extra: After the TV series. His appearances in season 3 were only a handful and so far only having one featuring role in season 4.
  • Everyone Hates Mimes: Inverted In-Universe. Most characters seem to like him and his tricks.
    • But why else would a mime be in a show relying on pain and death?
  • Half-Dressed Cartoon Animal: Wears no pants.
  • Nonverbal Miscommunication: He does not speak, but there have been several instances where he tries to make a phone call...and miming over the line.
  • Official Couple: With Petunia at first, before she started dating Handy.
  • Only a Flesh Wound: In Wingin' It, he gets run over by the plane after parachuting to the ground using his face. After getting ran over, his eye turns toward the camera, and blinks, showing that somehow, he survived being effectively turned into Ludicrous Gibs.
  • Poor Communication Kills: See The Voiceless below.
  • Throw the Dog a Bone: In the TV series, when a character has a "starring" role in an episode, expect them to be dead by the end. Mime survives both of his, even if the episodes themselves have downer endings.
  • Trademark Favorite Food: Peanuts, for some reason.
  • The Voiceless: In several episodes he makes brief vocal sounds, such as snoring, gagging, or gurgling. He most likely chooses not to speak or scream out of showmanship.
    • Deconstructed since this often leads to the deaths of those around him. One notable example was "Who's To Flame?" when he called 911 and didn't actually speak to Lumpy on the other end.
  • Your Mime Makes It Real: As shown in the episode "I Heart U" Mime can turn seemingly imaginary objects to actual reality.

    Lifty and Shifty 
"No need to be thrifty, just take whats nifty and be back in fifty!"
Both voiced by: Kenn Navarro

Two kleptomaniac green raccoon twin brothers, one of which (Shifty) is always wearing a green fedora. Lifty and Shifty often scam or steal from unsuspecting Tree Friends (mostly Lumpy) in an effort to get rich. They are played as sinister characters with narrow eyes, dark mask-like markings around their eyes, wide grins, and trademark evil snickers. Often times they work together to steal or scam, though they will sometimes fight, kill one another, or abandon the other to die in favor of riches or goods.

  • Alas, Poor Villains: See Pet the Dog.
    • In general, they suffer from some of the lowest survival rates in the show and almost always die in whatever episode the pair appears in, and unlike some characters who die often and get better treatment, Mondo has never been nice to these two. It doesn't help that the reason they steal is implied to be because they are/were dirt poor.
  • Asshole Victims: They die in most episodes they appear in. See Jerkass below for why they deserve it.
  • Cain and Abel: If an opportunity would present itself, Shifty would be the first in leaving Lifty to die. It never ends well for him.
  • Can't Get Away with Nuthin': They have died in EVERY episode of the internet series so far.
  • Cheshire Cat Grin: Often seen with this, this is their trademark feature, along with their laughs.
  • Death by Materialism: A common cause of death or injury for them. See the Sea What I Found example below for an example.
  • Dirty Coward: Shifty. He'll gladly leave his brother to die or even kill him directly if the alternative endangers his own life or their loot.
  • Evil Laugh: They are very well known for their laughs, which crosses into Giggling Villain territory. There's even a compilation of them (as of July 23rd, 2011).
  • Evil Genius: To a certain degree of "genius", Lifty seems to be this for the duo, as he is the one seen working on their van and handling equipment.
  • Five-Finger Discount: Though they really have Four-Fingered Hands.
  • Green and Mean: They have green fur.
  • Giggling Villain: They like to do evil laughs a lot.
  • Harmless Villain: Subverted. While most Tree Friends (barring Fliqpy) will not kill another intentionally in many cases, these two do not have any qualms about harming others or each other to reach their ulterior goal. This includes straight-up murder.
  • The Hyenas: They are constantly performing their evil laughs, sometimes for no reason.
  • Heel–Face Revolving Door: They are sometimes seen helping others, and other times committing crimes.
  • Identical Twin ID Tag: See Nice Hat below.
  • Informed Attribute: According to the "Collect Them All" section (From the "First Blood" DVD), Shifty has a gambling problem.
  • Jerkasses: They swindle, steal, and pillage from the other characters on a regular basis, even if it sends their victims to their deaths.
  • Jerk with a Heart of Gold: See Pet the Dog.
  • Karmic Death: Most of their deaths are a result of their thievery. Shifty also tends to suffer worse fates between the two for attempting to kill his brother more often than not.
    • In Don't Yank My Chain, they steal a car at a gas station. At the end of the episode, they get run over by a train when the car runs out of fuel right on the track. As a bonus, the original owner(s?) of the car are being dragged along the train when this happens.
    • In Sea What I Found, Shifty chooses to save the jewelry Lifty is carrying rather than Lifty himself when the latter gets pinned under an iron bar. The underwater volcano they're over soon proceeds to melt the gold, which covers Shifty. Lifty in turn survives relatively unharmed, only to drown when he tries to grab his now golden brother (presumably to sell).
  • Laughably Evil: Like the others, their deaths are mostly played for laughs. What makes these two even more hilarious is that they have it coming in many cases. Sometimes, you just have to root for the two.
  • Laser-Guided Karma: "Laser-Guided" is a bit of an understatement...since they have the lowest rate of survival of all of the characters.
  • Lovable Rogues: Downplayed a bit on the 'Lovable" part, but sometimes, you just gotta root for them for mischief.
  • Nice Hat: Shifty wears a fedora to differentiate the two.
  • Pet the Dog / Out-of-Character Moment: In Happy Trails Part 2: Jumping the Shark, when they try to save everyone by using an inflatable raft to bring everyone back to civilization. Too bad that didn't work quite as they planned.
  • Rascally Raccoon: They are the de facto villains of the series.
  • Sibling Rivalry: They're sometimes seen fighting over who gets to rightfully keep things they have stolen.
  • Sibling Team: For kleptomania, no less.
  • Sociopaths: Sometimes.
  • Throw the Dog a Bone: After dying in every appearance they had in the internet shorts, the television series sees them surviving a few episodes.
  • Together in Death: Though their deaths may be spaced out, if one of the siblings die in an episode, the other one falls not too far behind. The only episode (or rather, Break) that averts this is Cheesy Does It, where Shifty has his face melted from insanely hot pizza as Lifty suffers from nothing.
  • Too Dumb to Live: Their thievery usually goes against common sense, and usually gets themselves killed.
  • Trademark Favorite Food: A Running Gag in the series is them stealing various meats or cows.
  • The Unintelligible: While other characters can be understood if one listens to them closely enough, Lifty and Shifty usually only speak in complete gibberish. There HAVE been a few times where they can be understood.
  • You Have Outlived Your Usefulness: Shifty tends to either kill or leave Lifty behind in order to escape with their loot.
  • Villain Protagonists: Usually, the episodes they appear in center around them.

"Row, row, row your boat down a running river!"
Voiced by: Francis Carr

A turquoise pirate sea otter with a Jolly Roger hat, eye-patch, ripped striped shirt, black pants, two peg legs, and a hook hand. Russell dresses and talks like a pirate, with his vocabulary consisting almost entirely of "Yar!" He enjoys the sea and nautical activities, such as fishing, sailing, or hunting for treasure, and he even lives in a house boat (perched in a tree). His early design had him with five-o-clock shadow, but this has been retired since his second appearance onward.

    Disco Bear 
"Don't be a drag. Get down and dance! Can you dig it?"
Voiced by: Peter Herrman

A groovy golden bear with an orange afro, yellow leisure suit, yellow bell-bottoms, and platform shoes. Disco Bear is stuck in the 1970's and lives the disco way of life, from his clothing to his dance moves to the music that plays on his alarm clock. He likes to roller blade, ski, and (unsuccessfully) hit on Giggles and Petunia, but most of all he loves to disco dance. However, he also loves deep fried/fatty foods, has a noticeable gut, and lives an unhealthy lifestyle. He takes great pride in his afro and goes to extremes to make sure it's perfect. It took until the TV series for the creators to stop finding him annoying and actually start liking him.

  • Asshole Victim: Sometimes.
  • Balloon Belly: During "Ipso Fatso".
  • Bears are Bad News: Subverted, he's not always a villain but he is a selfish egomaniac.
  • Big Eater: In "A Change Of Heart", he orders a lot of food at the cafe, leading to his heart attack.
  • Big Ego, Hidden Depths: "Easy Comb Easy Go" hints he fakes his egoism.
  • Casanova Wannabe: Continuously flirts with the female characters throughout the series. The only female he has not flirted with is Lammy.
  • Catch Phrase: "Oh yeah."
  • Deep-Fried Whatever: Which lead to bad consequences in A Change Of Heart and Ipso Fatso.
  • Disco Dan: Lives in a house with typical 1970's paraphernalia, such as shag carpeting and wood paneling. In early episodes a disco ball would appear out of nowhere to signal his arrival. He even wakes up to it on his alarm clock.
  • Fat Comic Relief: In "Ipso Fatso".
  • Fat Bastard: When he temporarily gained a fat belly in "Ipso Fatso".
  • Flat Character: Before the TV series, that is.
  • Funny Afro: Often seen caring for it.
  • Inferiority Superiority Complex: "Easy Comb Easy Go" suggests he might not be as egotistic as he acts.
  • Informed Deformity: In "Ipso Fatso", he had a flabby gut due to his poor diet and lifestyle.
  • Narcissist: Admiring his good looks, to the point where his self-esteem drops at the sight of imperfections.
  • Laser-Guided Karma: At the end of "Ski Ya, Wouldn't Wanna Be Ya!"
  • Out of Focus: He has only made a whopping 3 appearance roles in season 3.
    • Season 4 however seemed to have finally Subverted this after getting another starring role in "Put Your Back Into It"
  • Screams Like a Little Girl: For a character with a deep voice, he screams in a high-pitched voice when he's in pain.
  • Traumatic Haircut: In Easy Comb, Easy Go.

Voiced by: N/A

A prehistoric yellow marmot who wears a leopard-skin loincloth and carries a club. Cro-Marmot is always seen encased entirely in a large block of ice (except for the irregular episode Dino-Sore Days). Despite this, he will often be seen doing activities (almost always off-camera), and is apparently known for his impressive talents, all unseen by the viewer. His main method of transportation is an ice cream truck.

    Flippy and Fliqpy
"Fire fried food is a feast for a famished soldier."
Voiced by: Kenn Navarro (Flippy), Aubrey Ankrum (Fliqpy)

A war-torn green bear who wears a military jacket, beret, and dog tags. His rank is apparently sergeant (by USA stripes; other countries have other rank insignia).

Flippy suffers from severe post-traumatic stress disorder due to the time he spent in the W.A.R (Weaponized Animal Regiment). While his "good" side tends to be one of the kinder and more sociable of the Tree Friends, his 'evil' side "Fliqpy" will emerge whenever he sees or hears something that reminds him of war or death. Once in his evil state (usually dubbed "Fliqpy"), he turns into a highly efficient killing machine, slaughtering everyone around him. He is arguably the most popular character of the series among fans. He stars in Ka-pow! alongside Splendid and Buddhist Monkey. Is revealed to be allergic to venison in "Party Animal".

  • Alas, Poor Villain: He doesn't die often, and when he does it's a particular sore spot for the fanbase.
    • To date he's died in Jumping the Shark, Remains to be Seen, Class Act, Hear Today, Gone Tomorrow, Double Whammy/Autopsy Turvy, Without a Hitch, Claw / Youtube Live Episode (Confirmed by the creators), A Vicious Cycle and By the Seat of Your Pants. A relatively low count for a Tree Friend.
  • Anti-Hero: In Operation: Tiger Bomb.
  • Anti-Villain: Type II
  • Art Evolution: The show took a while to settle on his appearance while flipped out. In his very first episode he actually looked just like normal Flippy. After that he was drawn with crooked teeth for a while, until these were finally replaced by fangs.
  • Ax-Crazy: His flipped-out state.
  • Badass Adorable: Flippy can still put up a pretty tough fight even when he isn't flipped, as we see in Double Whammy.
  • Bears are Bad News: Flippy actually plays with this trope, being one of the nicest characters in his normal state. However, when he does flip out, he becomes an Ax-Crazy serial killer.
  • Beary Friendly: His good side plays this straight as an arrow.
  • Berserk Button: If Flippy encounters anything that reminds him of war: RUN, BITCH, RUN!!!.
  • Beware the Nice Ones: Flippy is one of the sweetest characters on the show, just as long as he doesn't turn into Fliqpy...
    • He also kills Flaky in "Happy Trails Part 2" after she accidentally pops the raft with her quills. It's noticeably the first time he has intentionally killed someone when not in Fliqpy mode.
  • Big Bad: Fliqpy can be considered this due to his large role throughout the series and routinely killing people in all of his starring roles.
  • Bruiser with a Soft Center: Fliqpy is a scary, murderous bear, but is a big softie in his "Flippy" persona.
  • Conservation of Ninjutsu: In "Double Whammy" an army of evil Flippys and a army of good Flippys are much less resistant than the originals.
  • Creator Cameo: Both of the voice actors (good and evil) are creators of the show.
  • Creepy Shadowed Undereyes: He gets these whenever he goes into Fliqpy mode.
  • Curtains Match the Window: While he normally has black Pac-Man-like eyes like the rest of the tree folk, he gains Green Eyes when he flips out, which is a darker shade than his light green fur.
  • Dark and Troubled Past: We aren't given too many specifics about his actual time in the W.A.R. until Operation: Tiger Bomb where it was revealed that the first time he flips out was after killing his teammates by accident and having to hide in one of their corpses to survive.
  • Death Glare: Fliqpy's default face whenever he isn't having a Slasher Smile.
  • The Determinator: Fliqpy seems to try to kill Lumpy more obsessively than he does with the other characters, and goes to great lengths to do, the biggest examples being: "Remains to be Seen", "Hear Today Gone Tomorrow", and "By The Seat Of Your Pants", and in all of those episodes, he dies while Lumpy manages to survive.
  • Demonic Possession: Fliqpy possesses Cub's bike in "A Vicious Cycle" after being struck by lightning holding it.
  • Disproportionate Retribution: He, along with Lumpy, Handy, and Sniffles, kills Flaky (despite not flipping out), just for accidentally popping the raft with her quills.
  • Even Evil Has Standards:
    • In some episodes, it's implied that Fliqpy only kills to defend himself because he thinks he's still in the war.
    • It is hinted that he only hurts those that can defend themselves. It depends on the episode, though.
  • Evil Laugh: Fliqpy has a normally deep one, though he uses a more raspy variant in Party Animal.
  • Evil Sounds Deep: Fliqpy's voice is much deeper than Flippy's.
  • Expy: Of Rambo. In his first appearance, his kills mirror that of Rambo.
  • Eye Scream: Flaky stabs him in the eye in "Without a Hitch", suffering from her own Sanity Slippage due to remembering her various deaths at his hands (keep in mind that he never flips out in the episode whatsoever). This leads to him getting hit by a truck.
  • Fangs Are Evil: One of Fliqpy's main distinguishing features.
  • Green and Mean: As Fliqpy.
  • Hair-Trigger Temper: Anything that reminds Flippy of war will trigger his evil side.
  • Heavy Sleeper: As seen in Easy For You to Sleigh and Hear Today, Gone Tomorrow. In the former, Lifty and Shifty drop a vase on the floor, accidentally turn on the TV, tie him up, and drive a forklift around his house, and he doesn't even stir until they try to steal his cookies and drop a crumb on the floor.
  • Half-Dressed Cartoon Animal: Wears no pants.
  • Helicopter Blender: In Hear Today Gone Tomorrow.
  • Improvised Weapon: Fliqpy has a knack for transforming nearby objects into lethal weapons, such as a movie projector, a propeller blade, a rose, a straw, and even a Christmas cookie.
  • Jekyll & Hyde: Flippy and Fliqpy are complete polar opposites of each other, yet Flippy is the only character who can hold his own in a fight with Fliqpy.
  • Karma Houdini: While Flippy often dies, the same can't be said for Fliqpy.
    • Though Fliqpy not dying is inverted in Remains to be Seen and By the Seat of Your Pants.
  • Karmic Death: In Remains to be Seen, Fliqpy first gets killed when he rams his truck to a tree, killing himself and everyone near him. Then he becomes a zombie and dies again when he gets his brain stuck to a leaf blower and a zombified Toothy bites his brain, causing it to explode.
    • Also happens in By the Seat of Your Pants, when he attacks Lumpy, only for him to bounce off of Lumpy's shortened skin (used as a swim trunk) and be impaled by a flagpole (which he survives), where he then attempts to climb out of it, only to be roped down by Lumpy, disemboweling and killing him. Thus, Lumpy is now considered the third character to intentionally kill Flippy (the first be the zombified Toothy, and, indirectly, Flaky, though the latter killed him while he was not flipped out).
  • Knife Nut: A bowie knife is his iconic killing tool; not that he needs it.
  • The Millstone: In Operation: Tiger Bomb, he's singlehandedly responsible for the deaths of his teammates and the mission going to hell in a handbasket... until he flips out for what is implied to be the first time and cleans house.
  • Mood-Swinger: While this is not his disorder, and merely triggered by his Berserk Button, he can go from heartwarmingly friendly one minute to a cold-blooded killer the next.
  • Nice Guy: As Flippy.
  • Obliviously Evil: Flippy never knew that he was killing other Tree Friends until Double Whammy.
  • Pet the Dog: His episodes contain some moments of this for Flaky. In episodes such as Party Animal, Without A Hitch and Random Acts of Silence, he doesn't purposely kill her despite killing everyone else around him. This is often seen as either an Relationship Writing Fumble or Fanservice from the creators for the most popular Fan-Preferred Couple.
    • One of the most famous example is in "Hear Today, Gone Tomorrow" in the episode, Fliqpy tries to shred Lumpy with his helicopter, he then imagines a familiar scene of his good self riding his unicorn, and cries before flipping back and deciding to save Lumpy.
  • Rasputinian Death: See Karmic Death.
  • Plot Allergy: Venison, in the episode "Party Animal".
  • Real Men Wear Pink: Besides collecting weapons in his bunker-house, he likes flowers, tea parties, pink penguins and unicorns.
  • Recurring Riff: Typically, when Flippy is triggered enough to start killing, his transformation is triggered by a quite literal Recurring Riff: a low, descending guitar tone and background sounds of warfare.
  • Scary Librarian: In Random Acts of Silence when he flips out.
  • Shell-Shocked Veteran: His post-traumatic stress disorder had manifested itself into both schizophrenia (having hallucinations of his evil self and of many versions of himself and his evil self going into battle) and Split Personality (he becomes an entirely different person when something reminds him of war and he doesn't remember the things he's done as his other self either).
  • Ship Tease: Taking the show's standards into account, he is this with Flaky, particularly "Lesser of Two Evils" on both parts and "Without A Hitch" on Flippy's part. In his flipped out state in "Lesser of Two Evils", "Random Acts of Silence" and "Double Whammy" Flaky is the only character he doesn't kill. In fact, she snapped him out of his flipped out state once with her screams.
    • Not that he hasn't ever killed her, however. He's murdered her in his debut, even.
  • Slasher Smile: Fliqpy, always.
  • Split Personality: See Jekyll & Hyde.
  • Super Mode: As of recently, Flippy can trigger Fliqpy mode on the word go, as seen in "Random Acts of Silence"
  • Super Strength: He once stopped the blades of a biplane with his bare hands during a flip-out.
  • Taking You with Me: Fliqpy manages to pull this off in Remains to be Seen, driving his truck straight into the Tree Friends, killing himself in the progress.
  • Trigger: Has many relating to war that will cause his flip-outs; some examples being popping sounds, fire, sharp objects, and gunshot-like noises.
  • Villain Protagonist: Though not intentionally, once Flippy flips out, he kills other characters without remorse or mercy.
  • Woobie, Destroyer of Worlds: PTSD is a devastating mental illness, and it's very easy to feel sorry for Flippy, even though he has the second-highest kill count in the series.
  • Would Hit a Girl: Would kill one, in fact. He's killed Flaky, Giggles and a few others on occasion.
  • Would Hurt a Child: He kills Cub in "Flippin' Burgers". Word of God also implied that Fliqpy killed him at the end of "A Vicious Cycle".

"Super squirrel swooping in for the save!"
Voiced by: David Winn

A heroic blue flying squirrel who is always seen with a red mask. Splendid is a superhero with super strength/speed, heat vision, the ability to fly, and more. Despite his helpful nature, he always seems to hurt more than he helps. When not saving the world, he's quite the homemaker who enjoys baking and sewing. He is a comic book legend in-universe, and is an idol to Sniffles and Toothy in particular. His only weakness is a green acorn-shaped rock called Kryptonut, which caused his only on-screen death throughout the whole series (The only other death being in "Class Act"). He has an evil twin/evil counterpart, Splendont, who ironically is much better at being a superhero. Splendid stars in Ka-pow! alongside Flippy and Buddhist Monkey.

    Lammy and Mr. Pickels 
"Long lasting friends don't tend to be fickle. More likely, they would laugh and love to tickle!"
Voiced by: Renée T. MacDonald
Mr. Pickels

A wooly violet lamb who wears a purple hairbow and a white wool sweater, and a pickle dressed in a top hat and mustache. Winners of the Vote or Die 10th anniversary new character contest held by the Happy Tree Friends website in early 2010, Lammy and Mr. Pickels are the newest additions to the HTF cast. While Lammy appears to be a relatively normal girl, her (seemingly imaginary) friend Mr. Pickels gleefully causes mischief with others, even killing them. As a disturbing twist, when Lammy tries to stop Mr. Pickels from harming others, it's Lammy unintentionally causing pain and grief.

  • Ax-Crazy: Mr. Pickels (intentionally), and Lammy (unintentionally).
  • Beware the Nice Ones: Lammy is a friendly sheep, but apparently is the one accidentally doing all the killing whilst she imagines Mr. Pickels is doing it.
  • Companion Cube: In A Bit of a Pickle, Mr. Pickels is shown to be a regular pickle that Lammy considers her Imaginary Friend.
  • Expy: Of the Ventriloquist. Both are mild-mannered, friendly people with a murderous Maybe Magic, Maybe Mundane 'imaginary' friend and companion.
  • Eye Scream: In their debut episode, Lammy is shot in the eye with a taser, and then electrocuted. We later see her with her eye horribly swollen, dark red, and covered in welts.
    • Actually, if you pause while she's being tased, you'll notice she has a crack in her skull. Hmm...
  • Hair Decorations: Lammy wears a bow.
  • Imaginary Friend / Not-So-Imaginary Friend : Mr. Pickels can be either one of these tropes.
    • Royal Flush seems to show that Mr. Pickels is not just in her imagination, as he kills Flaky while Lammy's whereabouts are accounted for. Note that Mr. Pickels pulls the rug from under Flaky when he's supposed to be in the toilet.
  • Green and Mean: Mr. Pickles, a psychotic murderous pickle.
  • Half-Dressed Cartoon Animal: Lammy only wears a shirt.
  • Nice Girl: Lammy, whenever she isn't actually killing people.
  • Nice Hat: For a pickle, anyway.
  • Nice Job Breaking It, Hero!: Lammy's attempts to stop Mr. Pickels end in death and disaster.
  • Pokémon Speak: Lammy speaks with a sheep's bleat. It's most pronounced when she's laughing or panicking.
  • Spell My Name with an "S": Yes, it's meant to be "Pickels."
  • Split Personality: It's implied that Mr. Pickels is the result of Lammy having Dissociative Identity Disorder.
  • Tertiary Sexual Characteristics: Lammy has long eyelashes and, like Giggles, wears a bow on her head. Mr. Pickels, on the male end of the spectrum, wears a top hat and has a mustache.
  • Tomboy And Girly Girl: Lammy is the girly girl to Flaky's tomboy.
  • The Voiceless: Mr. Pickels
  • Yandere: Mr. Pickels doesn't like when Lammy shows affection to others...

Other Notable Characters

     The Ant Family
Voiced by:Kenn Navarro, Ken Pontac, Warren Graff

A family of ants who are Sniffles' arch-enemies. Small but surprisingly deadly.

  • Berserk Button: They have a tendency to act violently whenever Sniffles attempts to eat them.
  • Cold-Blooded Torture: They inflict this on Sniffles whenever he tries to eat them.
  • Disappeared Dad: The family consists of a baby, a brother, sister, and mother ant. Where's the father ant? Some fans assume he died prior to the series; most likely eaten by Sniffles.
  • Disproportionate Retribution: Why must they torture that poor anteater who only wants a snack?
  • Four-Legged Insect: They also lack antannae, except the baby ant who has one antenna on his head like a strand of hair.
  • Even Evil Has Loved Ones: They do seem to care about each other.
  • Karma Houdini: They ALWAYS get away with torturing and killing Sniffles. The closest thing they got to a comeuppance was the baby ant catching Sniffles' cold at the end of "Suck It Up".
  • Mama Bear: In "A Hard Act to Swallow", the mother ant attacks and goes inside Sniffles to rescue her youngest offspring, who was eaten at the beginning of the episode.
  • Put on a Bus: Since "Tongue in Cheek" back in 2006, they have made no appearances in the show, being absent for all of Season 3 and, so far, Season 4 of the Internet series.
  • Sadist: Their torture methods would make even Fliqpy wince.

     The Cursed Idol
A mysterious golden object that causes death and destruction to anyone near it.
  • Artifact of Death: Just being near it will guarantee you a death.
  • The Cameo: Similarly to Truffles, the Idol can be seen hidden in the background on several episodes.
  • A Day In The Lime Light: "Treasure Those Idol Moments", "Hello Dolly" and "Idol Curiosity".
  • Demoted to Extra: Hasn't made a starring role since "Idol Curiosity" in 2006.
  • Expy: Of the Fertility Idol.
  • Even Evil Has Standards: It was willing to pay for the taxi's fare in "Idol Curiosity" rather than just killing the driver.
  • Reality Warper: The Idol can bend the laws of physics whether it be body-piercing coils or sentient earthquakes just to kill any of the main characters.

     Lumpy's Elephant
A non-anthropomorphic purple elephant that belongs to Lumpy.

     Generic Tree Friends

Background characters who, very much like the main cast, can be caught up in messed-up gory glory.

  • Faceless Masses: Mostly their faces aren't shown. One of the few exceptions being "Class Act", where Flippy is briefly shown stabbing one to death in the background.
  • Put on a Bus: They haven't made an actual physical appearance since "Wrath of Con"
  • Recurring Extra: Usually seen in the background.
  • Reused Character Design: As of "Class Act", they all look very similar to Toothy.

A blue pig who was rejected in favour of Lammy and Mr. Pickles. His numerous cameo appearances seem to serve as a Running Gag. The creators have confirmed that he will never have a larger role in the series.

  • Anyone Can Die: He's been killed three times so far ("All in Vein", "By the Seat of Your Pants" and "An Inconvenient Tooth"), but all his deaths occur offscreen.
    • It's also worth noting that he has the second highest survival rate of all the characters (Excluding Buddhist Monkey and the Ant Family) with number one being Mr. Pickels.
  • Blowing a Raspberry: Seen doing this as one of his poses.
  • The Cameo: Ever since he lost Vote or Die to Lammy & Mr. Pickles, Truffles could only appear through making small cameos in the background of episodes. Ironically, however, he makes more appearances than Lammy & Mr. Pickles.
  • Demoted to Extra: Only has non-speaking cameos.
  • Flat Character: Mostly due to the fact that he will never have his own episode.
  • Non-Standard Character Design: Like Lumpy and Sniffles, he lacks the common nose style of most characters. While distinctly heart-shaped, it is bigger, has visible nostrils, and is more purplish in color. He also lacks normal hands and feet, having hooves instead, as well as being the only character to bear tusks. His ears and tail are unique as well.
  • Running Gag: His constant cameos throughout the series starting in "A Bit of a Pickle".
  • Spoiled Brat: Truffles has been referenced as a brat by the creators. His personality could also be hinted by his appearance.
  • Silent Bob: We've never heard his voice. At least not yet.

    The Demon
A strange squid-like creature that possesses Cub in the episode "Read em' and Weep"

Ka-Pow! Characters

     Buddhist Monkey 
Voiced by: Jeff Biancalana

A peaceful orange monkey who wears a dark orange Buddhist robe and large prayer beads. Buddhist Monkey is, as his name suggests, a monkey who practices Buddhism and is normally nonviolent. However, when attacked by Generic Tree Ninjas and others sent from a mysterious, dark overlord, he sheds his passive outer nature and call upon his extensive martial arts training to kill his enemies. A flashback focused on his training by Sensei Orangutan, who had died sometime between the flashback and the series. He is the only main recurring character to not have died yet (although the fact he's only appeared in person in Ka-pow!! helps immensely). He stars in Ka-pow! alongside Flippy and Splendid.

     Tiger General 
Voiced by:Ken Pontac

Leader of the Tiger Soldiers, bent on world domination. Flippy and his squad were sent to assassinate him and foil his plans.

     Sneaky and Mouse Ka-Boom 

Flippy's squadmates, dispatched to take down the Tiger Army. Unfortunately, both of them died due to Flippy's incompetence.
