-->''"Cute, Cuddly, and [[BreadEggsMilkSquick Horribly Wrong]]"''
-->-- The show's {{tagline}}, which sums things up quite well

''[[http://happytreefriends.atomfilms.com/ Happy Tree Friends]]'' (1999-present) is a series of web-based (and later televised) animated shorts. The series stars a [[GangOfCritters gang of]] [[AmazingTechnicolorWildlife colorful]] [[RidiculouslyCuteCritter adorable animals]] that live in a [[SugarBowl bright and]] [[TastesLikeDiabetes happy world]] -- [[TemptingFate right?]]

Actually, [[CrapsaccharineWorld they live in a world]] where each and every character is [[TheChewToy a chew toy]] doomed to suffer a [[NightmareFuel nightmarish]], [[{{Gorn}} gorn-filled]], and [[NauseaFuel absolutely disgusting]] demise. Expect horrific things to occur OnceAnEpisode to the [[BodyHorror body]] and less frequently to the [[EyeScream eyes]]. It is one of the most prominent among series in wide circulation that CrossesTheLineTwice, since it's designed to [[NightmareFuel horrify]] and [[NauseaFuel gross out]] people to such extremes that we [[BlackComedy laugh]]. SubvertedKidsShow [[UpToEleven doesn't even begin to describe it.]]

After you pick up your [[JawDrop jaw from the floor]], you'll be laughing your guts out (not literally, though the show ''does'' do that a few times) -- and subsequently lose all faith in humanity and compassion for your fellow man in the process. It doesn't help that the SickeninglySweet characters and setting so perfectly emulate a number of the most [[PeripheryHatedom annoying children's shows ever]] (they even have ''{{Carebears}}''-esque hearts for noses!) or that the poor critters are [[NegativeContinuity endlessly resurrected]] between episodes [[TheManyDeathsOfYou to die in new ways]] that even [[TheyKilledKennyAgain Kenny]] would wince at.

This show has a [[Characters/HappyTreeFriends Character Sheet]] and a well-deserved [[NightmareFuel/HappyTreeFriends Nightmare Fuel]] page to seal away the show's scares.

The series also has a really popular {{Fanon}} [[JustForFun/HappyTreeFriendsTheAnime anime version]].

----
!!This show provides grisly examples of:

* [[AbsurdlySharpBlade Absurdly Sharp Everything]]
* AddedAlliterativeAppeal: The alliterative sentences for characters in starring images for the 3rd season. It was even lampshaded in the Wrath of Con Blurb. "'Wrath' was the first episode ever to be entirely developed in HD...and inventively initiated illiterated illustrations into the titles!"
* AdultFear: Anything involving Pop and Cub.
* AdultsAreUseless: Very much so in Pop's case. As well-meaning as he is, his lack of attention and ineptitude often leads to Cub's death (and occasionally his own). Lumpy also falls under this banner in episodes such as "From A To Zoo", and when Giggles' Mom shows up for the first (and probably last) time, she doesn't notice when her daughter's head is replaced with an acorn... or when it falls off, squirting blood in her face.
* AlwaysChaoticEvil: Well not always, but whenever you see birds in this show you should probably start running. Particularly the man-eating [[MorallyAmbiguousDucktorate ducks.]]
* AmazingTechnicolorWildlife
* AmbidextrousSprite: The Mole's mole, Lumpy's inverted antler, Russell's hook hand and eye patch, and Nutty's lazy eye tend to change from side to side, often in contiguous shots. This is done so often that it almost seems intentional.
* AmbiguousGender: In the show, Flaky's gender is never directly stated and has led to some confusion; WordOfGod is inconsistent on the subject. Jokes about her gender confusion are sometimes slipped into the show because one of the writers, Kenn Nevarro, finds it hilarious to watch people argue over his gender.
* AmusingInjuries: Played straight or subverted, depending on how realistically the injury is depicted.
* AnAesop: If the series has any fairly consistent aesop, it's household safety. It's quite impossible for parents to claim that the shorts set a bad example for small children, since many of the deaths involve accidents caused by playing with kitchen tools, matches, and the old favorite, not turning something off at the plug. Alternatively, the characters make very certain to turn things off, and it's something else that causes the accident.
* AndIMustScream
* AndKnowingIsHalfTheBattle: Each episode ends with a lesson, cheerful thought, or general admonition like "Don't forget to brush your teeth!". Since these were inserted into the Television Series, they now have some distant relation to the lesson you should have learnt.
* AnyoneCanDie: Taken UpToEleven several times.
* ArtEvolution: The character designs were refined over time, becoming less stiff and a little "cuter." For instance, the characters' buck teeth are rounder, and Sniffles' snout has gotten shorter. The animation has also gotten smoother over time, and the deaths have become more graphically detailed.
** Now with a [[http://images1.wikia.nocookie.net/happytreefriends/images/4/4e/Happy_Tree_Friends_Art_Evolution.jpg comparison!]]
* ArtStyleDissonance: If all you saw were the characters and backgrounds, you'd never in a million years guess [[DeathAsComedy the show's true premise.]]
* ArtifactOfDeath: A cursed idol which appears in several episodes, most notably ''Treasure These Idol Moments''.
* AssShove: When Toothy flies off his bike seat in ''Brake the Cycle,'' he lands on the seat part minus the seat. [[ThePratfall Ouch.]]
* AsideGlance: Whenever Handy's lack of hands inconveniences him, he glares into the camera.
* AxCrazy: Flippy, when his evil side emerges, will kill everyone around him with no remorse.
** Quite ''why'' he's so utterly insane under his outgoing, if nervous, exterior was explored in the short ''Operation Tiger Bomb''. Let's just say it cemented Flippy's status as the most batshit crazy character in the series.
* {{Badass}}:
** Flippy. In his evil state, he is able to make almost anything lethal. ''Double Whammy Part 2'' reveals that his good side is equally badass.
** Lumpy also gets a few moments where he goes from bumbling to badass. In ''Doggone It'' he takes on a giant squid... with a mousetrap. And wins. Unfortunately for him and all involved the [[TookALevelInBadass level in badass]] doesn't last. He gets another moment of badass in the halloween episode ''Read 'Em and Weep'' when he takes on a demonic Cub, though infection by {{The Corruption}} is hinted at at the end.
* BaitAndSwitch: The reason why ''Random Acts Of Silence'' dragged out for several minutes until Flippy finally flipped out, despite being provoked with war-reminding sounds repeatedly.
* BananaPeel: Subverted in ''Ipso Fatso''. Lumpy notices he's about to step on one, and lifts his foot over it... only to see that the floor also has nails, a snake, spikes, a frayed cord and ''lava'' in various places.
** [[DoubleSubversion Then he falls over anyway]] back outside and onto a bike, breaking his spine.
* BattleCry: Evil Flippy/Fliqpy, has a genuinely alarming one.
* BearsAreBadNews: Flippy plays with this trope, and when it ''is'' worse, that's an '''''understatement'''''.
** The actual wild bear that mauls Lumpy in ''Take a Hike''.
* BeatStillMyHeart: Lumpy's heart after Cub rips it out at the end of "Rink Hijinks".
* BeCarefulWhatYouWishFor: The premise (and the moral) of ''As You Wish''.
* BehindTheBlack: Cro-Marmot can only move when off camera.
** Similarly, Handy (who has no hands) will do things off camera like [[RuleOfFunny shovel snow and build an entire house]], but once he's on screen he can't do any of the same.
** The Mole is able to eat things off camera with his mouth covered all the time.
* BerserkButton: Don't do ''anything'' that reminds Flippy of the war...which happens to be a lot of things, making it more of a berserk ''''minefield''''!
** Subverted in ''Without A Hitch''. Flaky is hugely paranoid that Flippy will go insane and kill her, with three imagined deaths shown. He actually doesn't do anything bad at all. Consequently, she stabs him in the eye and he gets run over by a truck...
** Nor should you ruin a library or kill the Buddhist Monkey's plant.
** The Ants react very violently whenever Sniffles tries to eat them, but after he destroys their anthill, they proceed to torture him to death.
* BewareTheNiceOnes:
** Flippy is normally one of the nicest characters on the show, but once you [[BerserkButton remind him of the war]][[AxCrazy .]][[KillEmAll .]][[SlasherSmile .]]
*** Even ''Good'' Flippy gets this sometimes - he's one of the only characters that have killed someone for ''revenge''.
** Also, Lammy. Though she may seem very nice (and she is) she is schizophrenic and will kill you without meaning to whenever "Mr. Pickles is trying to kill you".
** Flaky is generally kind, if cautious. However, in ''Without A Hitch'', not only did Flippy ''not'' flip out, she flipped out for fear of him killing her and stabbed '''''him''''', which led to him getting run over by a truck!
* BigNo: Splendid when he discovers his bread is burnt in ''Better Off Bread''.
* {{Bizarrchitecture}}: The episode where everybody builds Giggles a new house. Because of scrambled blueprints, it ends up being a total [[strike:funhouse]] slaughterhouse.
* BlatantLies: The episode description for ''Happy Trails - Part 1'': "Is this really the end of the [[MadeOfPlasticine indestructible]] Happy Tree Friends?"
* BlowGun: In one short, Lumpy attempts to sedate a baboon mauling Sniffles, but accidentally sucks the dart in when taking his breath.
* ABloodyMess: Occurs in ''Flippin' Burgers'' where Giggles gets ketchup splattered on her and Flippy mistakes it for blood, causing him to flip out. Promptly inverted later in the episode, when Flippy dips a fry in Cuddles's blood.
* BaitAndSwitch: Why Flippy's BerserkButton was dragged out in ''Random Acts Of Silence'' for several minutes until he finally flipped out.
* BodyHorror: Every. Single. Episode. One that stands out is Cub in ''Read 'em and Weep''.
* BolivianArmyEnding: Subverted by accident. "Happy Trails - Part 1" was ''supposed'' to be this. At the time, they thought it would be the last ever episode of Happy Tree Friends, and at the end of the episode, the bus falls off of the cliff, with the words "to be continued." However, they ended up creating more episodes, the first of which resolved the cliffhanger.
* BloodyHilarious: To those who enjoy that kind of thing.
* BottomlessMagazines: Zig-Zagged in ''Double Whammy [[spoiler::Part 2]]''. While Flippy and [[spoiler:Evil Flippys']] staple guns do eventually run out of staples, they seem to hold more than should be possible.
* BreakTheCutie: Literally ''break'' them.
* BumblingDad: Deconstructed with Pop, in a world which pities no mistakes, or some seemingly safe decisions. If he's distracted by something, you can bet the results for Cub will be fatal.
* ByWallThatIsHoley: Subverted in ''A Hole Lotta Love'.' Cuddles looks like he's about to be saved this way, but the frame of the window cuts him apart. Played straight with Mime, though.
* TheCameo: Truffles, the other candidate from the ''Vote or Die'' event that Lammy and Mr. Pickles won against, occasionally shows up as a background character. [[AnyoneCanDie And, of course, he's been killed at least twice]].
* CaptionHumor: The Blurb version is all about this.
* CarnivoreConfusion: Flippy has eaten Mime's remains, and has drunk Cuddles's and Shifty's blood. This seems akin to cannibalism until you realize that Flippy is a bear, and the other three are a deer, a rabbit, and a raccoon respectively; suddenly, the issue becomes that much more complicated.
* CasanovaWannabe: Disco Bear. He always hits on female characters, but they don't see to care for him. There have been multiple occasions where, when the ladies he hits on are actually dying, he believes they are dancing.
* CensorBox: Lumpy gets one in the "Just Desert" Blurb reading: [[SelfDemonstratingArticle "Blurb placed for your protection!"]]
* ColdBloodedTorture: Whenever there's an episode with Sniffles and the ants. (shiver)
* ComedicSociopathy: Plenty of it. The characters' disregard for one another's safety is astonishing, though they might just be too dim to realize what they're doing to each other, seeing as they react with plenty enough horror when confronted with another dead character.
* CosmicPlaything: Any character in any situation is likely to be this. [[DoubleSubversion Often, they survive incredible things only to die from a throwaway detail anyway.]] See also: DiabolusExMachina, EverythingTryingToKillYou
* TheChewToy: Everyone, apart from Splendid and Cro-Marmot.
* ChekhovsGun: This is one of those shows where if you see some innocuous item or event early on, chances are it'll come back at the very last second to kill the last character who's still alive.
** That said, some characters definitely get the short end of the stick more than others. The likes of Splendid, Cro-Marmot and Flippy rarely ever die or even get seriously injured, and to a lesser extent Pop, The Mole and Lumpy die much less often than most other characters. Meanwhile the likes of Petunia, Sniffles, Lifty, Shifty and Cub suffer more than their fair share of the most cringe-inducing, sadistic deaths in the series.
* CrapsaccharineWorld: The world looks sweet and cuddly and so friendly that you can't imagine anything possibly dying in it...which makes it all the more hilarious when the inevitable bloody slaughter begins.
* CrouchingMoronHiddenBadass: See BadAss above.
* CruelAndUnusualDeath
* DeadlyRotaryFan:
** In "Party Animal", Flippy ties some balloons to Cuddles's neck, causing him to float up and get shredded by the fan.
** In "No Time Like The Present", Handy gets his foot stuck on the floor with a knife, so he gets a saw to cut a hole in the floor. He cuts right where the fan downstairs is, and Lumpy, who is right below it, gets his head sliced off when the piece of ceiling is detached.
* DeathAsComedy: In buckets. Then several more buckets.
* DeathIsCheap: ''And how''. By the end of the episode, at least one character (often more) will be dead or otherwise horrifically injured (e.g reduced to a burnt and bloodied mush after being set on fire and having it stamped out), yet you can guarantee that they'll be perfectly alive and well by the next episode, with no regards to any past deaths. Several of the main characters on the show have died ''over forty times in total''.
* DepartmentOfRedundancyDepartment: The television show was sometimes advertised as "Happy Tree Friends and Friends".
* DeliberatelyMonochrome: ''Without a Hitch''. It's silent also.
* DiabolusExMachina: Almost every episode. PlayedForLaughs.
** Most blatantly, "Swelter Skelter" where the deaths barely try to make sense. Nutty is tripped and his head breaks open like an egg. [[MindScrew And how else can ''frozen fire that turns back into fire when melted'' be explained?]]
*** [[ToonPhysics Rule of]] [[RuleOfFunny funny.]]
* DisasterDominoes: A character will be injured, they or others will panic, this panic will lead to a worse injury or death, leading to a wider panic which [[KillEmAll tends to kill off those left standing.]]
* DiscoDan: Disco Bear is stuck in the '70s.
* DisintegratorRay: In an episode where characters are competing for the brightest Christmas tree, [[LethalKlutz Lumpy]] goes a little too far, causing some folks who are exposed to the light to catch fire, and another to completely vanish, complete with charred outline on the fence behind him, a la Hiroshima bomb.
* DisneyDeath: Cub has one in "And The Kitchen Sink" when Pop believes he was decapitated, but he was only buried up to his head in sand. He does actually die later by drowning in the bathtub.
* DisproportionateRetribution: [[ShipSinking Flippy]], Lumpy, Handy and Sniffles killed Flaky in a gruesome way [[GoryDiscretionShot off-screen]] just because she stung a hole in the raft.
* TheDitz: Lumpy. His stupidity constantly endangers others and himself.
* DoesThisRemindYouOfAnything: The new character, Lammy is sweet and innocent. Until you think about the fact that her best friend is a pickle that makes her do evil things.
* TheDoorSlamsYou: Frequently and with gruesome consequences.
* DoubleSubversion: An example occurs in "Home Is Where the Hurt Is". Handy looks like he's about to pierce his foot on a nail, but moves his foot away from it... just in time to knock the board loose and drive the nail through his skull.
** Another case with nails (from "The Wrong Side of the Tracks"): Sniffles finds a rusty nail, gets disappointed, and throws it away. You'd think that Mime would get stung with it... only for the nail to pop Mime's balloon. Then Lumpy reacts to the sound by turning around so fast that the nails on the plank he's carrying get stuck on Mime's backhead, killing him. A nail ''did'' kill him after all!
* DrivesLikeCrazy: The Mole. Justified because he is blind.
* DrivenToSuicide: Petunia in ''Wishy Washy''. When she got covered in gunk, after several failed attempts to clean it off, she skins herself with a ''potato peeler''. OUCH!
** [[AlternativeCharacterInterpretation a popular interpretation]] is that she was trying to clean the dirt off her and tried the potato peeler since she had nothing else in her kitchen drawer that she hadn't tried yet'
* EarlyInstallmentWeirdness: The [[http://www.youtube.com/watch?v=-09DtJb4PLQ&feature=player_embedded very first]] episode from 1999, ''Banjo Frenzy,'' has little resemblance to the series other than gory deaths. Most notably, Lumpy is a dinosaur with a personality not unlike Flippy; Giggles is blue instead of pink; and the art style is almost nothing like seen in the actual series.
** The most unusual of all is that, after Toothy is decapitated, his head is somehow still alive and bites Lumpy in the foot. You'll never see something like that in the actual show.
* EverybodyLives: Nobody dies in "Nuttin' But The Tooth" and "Out On A Limb", but there is still blood. Several other episodes have no gore whatsoever, most notably "Asbestos I Can Do".
* EverythingsBetterWithPenguins: Flippy has tea with three pink penguins in [[MushroomSamba his hypnotism-induced "happy place"]] in "Double Whammy".
* EverythingsDeaderWithZombies: "Remains to Be Seen".
* EverythingTryingToKillYou: Whoo boy. The scenery, the antics of the other characters, and wildlife in particular.
* EvilSoundsDeep: Flippy's voice becomes deeper and more ominous whenever his SuperPoweredEvilSide takes over.
* {{Expy}}: Flippy is based on [[{{Rambo}} John Rambo]]. Heck, the first time he shows up ("Hide and Seek"), all his kills are shout-outs to Rambo's kills.
** Splendid is essentially the squirrel version of {{Superman}}.
** Lumpy looks so much like [[RockyAndBullwinkle Bullwinkle]], one of his antlers had to be inverted so he didn't look ''too'' much like him.
** A particularly obscure one is Sniffles, who may be based on the aardvark from ''TheAntAndTheAardvark'' shorts by the same guys as ThePinkPanther shorts.
* EyeScream: The series ''loves'' doing this.
** "Eyes Cold Lemonade" has Giggles blinded by a falling sign while she and Petunia are working a lemonade stand, and then later Petunia gets her face flattened by the other side of the sign falling. She's killed and her eyeball pops out and lands near Giggles, who's cutting up more lemons, and...[[{{Squick}} you can probably already guess where this is going.]]
** The music video they did for FallOutBoy's "Carpal Tunnel of Love." Toothy gets stung in the eye by a ''bee.'' Then it happens ''again.''
** "Eye Candy" is a famous example in which Toothy accidentally jams a lollipop into his eye socket and ends up pulling his eye out. The optic nerve hangs around a tree branch [[ToonPhysics somehow]], and then a woodpecker comes and...[[{{Squick}} yeah.]]
** Another example: both Toothy and Nutty get parts of their eyes sliced off by a rogue paper airplane in "Sight for Sore Eyes" and again, the show briefly cuts to their points of view (Toothy's being half forward, half backward, and Nutty's with big red spots in the middle). Russell averts the trope ''twice'' in the same episode: first, when Lumpy tries to examine his eyes with a dirty glove, and again when Russell puts in his contact lens with his hook hand.
** In "Easy Comb, Easy Go", Disco Bear pulls a hair out of his eye, slices the front parts off of them, AND has a huge mass of hair grow out of them... which he then tries to ''shave off''.
** In ''Blind Date'', guess what part of the body Disco Bear gets pepper sprayed to?
** ''A Bit of a Pickle'' includes Lammy getting taser wires straight to the left eye. Yeah.
** There's one in "We're Scrooged" where Lumpy gets a top's tip in his eye. Soon the top begins to ''drill into his eye''.
** In the episode "Without a Hitch", Flaky stabs Flippy in the eye with ''a shard of glass''. Then we get to see the world through his messed up POV.
** In the episode "Random Acts of Silence", Mime gets a papercut across his eye by Flippy.
** Pretty much the basis of [[MeaningfulName "Camp Pokeneyeout"]]. Nutty gets his eye burned by his marshmallow ([[spoiler:and by the end he is eyeless]]), and Cuddles beans Toothy with a rock so hard ''it leaves a dent in his eye''. Ouch. Petunia also gets her slingshot rammed into her eyes.
* FalseUtopia : the world is cute and perfect, but for some reason, the characters always die painfully.
* {{Fanart}}: A lot in anime style, [[http://www.zerochan.net/Happy+Tree+Friends?s=fav here]]
* FantasyGunControl: There are no guns that fire real bullets anywhere in the series (the only time when a gun shows up, in ''Concrete Solution'', it shoots nails). The writers' reason? "[[HaveANiceDeath Too]] [[TheManyDeathsOfYou easy.]]"
* FinaglesLaw: The only way of explaining some of the accidents. In one episode, Flaky manages to overcome her fear of flying in "Wingin' It", and heroically lands an out of control plane... [[ThreateningShark before a shark promptly chomps her.]] Then he spits her out... and then ''Franchise/{{Godzilla}}'' kills her.
* {{Fingore}}: Sniffles in ''Tongue in Cheek'', when he gets his hand sewn to the ground ''and'' one of his fingernails torn off ''AND'' salt on the exposed wound. ''[[{{Squick}} Oh, God...]]''
* FiveManBand: In "From A to Zoo" and "Take a Hike"
** TheLeader: Lumpy
** TheLancer: Cuddles
** TheSmartGuy: Sniffles
** TheChick: Petunia
** TheEveryman: Toothy
** TheHeart: Flaky
** [[SixthRanger Seventh Ranger]]: Nutty
* {{Flanderization}}: Flaky started out as afraid of actual dangerous situations (''Water You Wading For'', ''Ski Ya Wouldn't Wanna Be Ya''), to half-dangerous situations (''Mime To Five'', ''Wingin' It'') to almost ''anything'' (''A To Zoo'', ''Something Fishy'')
** Giggles started out as TheChick, but is now more of a GranolaGirl who ReallyGetsAround.
** Petunia started out as a PaletteSwap of Giggles, but then gained her NeatFreak tendencies as one of her unique traits.
** In the beginning, Fliqpy's killing sprees were just what happened and nothing more, to have those plots turn into more serious, advanced subjects and BaitAndSwitch moments. He also went from killing everyone, to [[ShipTease avoid killing Flaky]], to start killing her again on occasion.
* FlyingBrick: Splendid
* FracturedFairyTale: ''Dunce Upon A Time'', which parodies ''Literature/JackAndTheBeanstalk''. Lumpy is the giant.
* FurryConfusion: The episode "Take A Hike" has a grizzly bear slice Nutty in pieces and maul Lumpy to death. There are four anthropomorphic bear characters in the main cast (though none of them appeared in that episode).
* GangOfCritters
* GenreBlind: Everyone except for [[OnlySaneMan Flaky]].
* GenreSavvy: Flaky in particular, not that it helps her. Several characters are on edge around Flippy, but that doesn't help them either.
** Flippy is this in ''Double Whammy/Autopsy Turvy''.
* GoodVersusGood: Splendid vs. Splendont
* GoOutWithASmile: Giggles at the end of the Valentine smoochie.
* {{Gorn}}
* GoryDiscretionShot: Some deaths, although they often show the corpses anyway.
* GoshHornet: Bees are occasionally a cause of death, most notably with Nutty in "Sweet Ride".
* GreenRocks: Splendid's weakness is Kryptonut, as seen in "Gems The Breaks".
* GroinAttack: A rare female example occurs in "Home Is Where The Hurt Is". In one of the most painful-looking deaths in the series, Giggles slides down an incredibly long banister with nails sticking out of the top. She's groin-ground completely in half. Then there's Nutty in his Party Smoochie, where a [[KillerYoyo yoyo]] trick ends up hitting him in the crotch, grinding until the friction sets him on fire, and he ends up [[KillItWithFire burnt to death]].
** It's implied that the killer Turtle from ''Letter Late Than Never'' bites Lumpy in his lower areas too, given how he has plaster over both his crotch and behind in that episode.
* GrossoutShow: Though it's more focused on gory details than the usual ToiletHumour, though this does happen on occasion, such as in ''Breaking Wind''.
* GrotesqueCute: Evil Flippy.
* HalfDressedCartoonAnimal: Flippy, Pop, Lammy, Mime, and The Mole all wear only jackets/sweaters. Averted for Disco Bear, Russell and Truffles, however, since they wear full sets of clothing.
* HalloweenEpisode: A bunch of these come out per year that turn the {{gorn}} dial UpToEleven. Only one gets the title of that year's Halloween special. Examples include "Without a Hitch", "Peas in a Pod", and "A Vicious Cycle".
* HeatWave: ''Swelter Skelter'' is a ludicrously exaggerated example.
* HeliumSpeech: Cuddles in "A to Zoo". This being Happy Tree Friends, he later [[EyeScream impales his eyeball]] on the nozzle and inflates his other one, letting out a scream the becomes ridiculously high before stopping altogether.
* HereWeGoAgain: A few episodes end this way.
* HeroicComedicSociopath: There's a reason Flippy is one of the more popular characters.
** Splendid seems more than willing to get people killed while going after crooks.
* HighVoltageDeath: In the episode "In A Jam", Russel is electrocuted and reduced to ashes by a shorted amplifier at the beginning. Notable for being one of the most cartoony and least gory deaths in the series.
* HopeSpot: A lot of these happen. Notably, Flaky in "Mime to Five," after falling off of Cuddles' outstretched intestines and rebounding back up from a trampoline, visibly sighs in relief just in time to get bisected by Cuddles' intestine as she comes back up.
* HumanCannonball: Cuddles in ''Mime to Five''. It doesn't end well due to Toothy misinterpreting Mime's instructions, and therefore putting in two ''barrels'' of gunpowder instead of two scoops.
* IdiotHero: Splendid. And ''how!'' He has little care for his job and kills more people than he saves.
** Lumpy, quite frequently. He's the most common "last man standing" of the cast, even at times when he's the cause of it all (although it only happens when it's unintentional).
* IncrediblyLamePun: Pretty much every episode title is one of these, and sometimes the moral at the end is too.
* InexplicablyTailless: Giggles, type 1. She's a tailless chipmunk.
* InfantImmortality: Subverted whenever Pop and Cub are shown. Pop actually survives far more often than Cub, though that might be due more to his neglectful parenting.
* InstrumentOfMurder: In ''Double Whammy Part 2'', Flippy fights [[spoiler:an imaginary version of]] himself using instruments from a music store, such as recorders and a harp for bow-and-arrows, a cymbal for a shield (and somewhat of a frisbee), a guitar and Flippy gets knocked out by a trap with a piano.
* IrisOut: At the end of almost every episode.
** The recorder-arrows actually kill [[spoiler:Lifty and Shifty]]
* ItWasHisSled: Invoked in the blurb version of "Blind Date" after a Running Gag of "Same [insert object here] that Orson Welles used in ''Film/CitizenKane''."
* JerkAss: Lumpy at times, such as "We're Scrooged", where he's willing to let Toothy die just so he can sell his body parts.
** Nutty. He's even willing to steal a lollipop from Cub.
** Lifty and Shifty probably qualify the most. They have no problem stealing from others and even hurting them. In a couple of episodes, Shifty will kill Lifty to save himself.
* KarmaHoudini: Flippy often gets away with murdering as his evil self. His good self...not so much.
** Though the true masters of this trope are The Ants, who always get away with torturing Sniffles. The closest thing they got to Karma was when one of them caught Sniffles' cold.
* KarmicDeath: Lumpy (when portrayed as a villain), Lifty and Shifty.
** Flippy in ''Remains to be Seen'' and ''By the Seat of Your Pants''.
** Splendid in ''Gems the Breaks''.
** Arguably Sniffles each time he tries to eat the Ants.
* KillEmAll: Every character, excluding Buddhist Monkey, Panda Mom, and Giggles' Mom has died at least once. The latter has only had a role in ONE episode so far...
* KillTheCutie
* KillerRabbit: The ducks in ''Mime to Five'', a puppy (and, as it is later revealed, several dozen more) in ''Doggone It'', and the turtle in ''Letter Late Than Never''.
* LampshadeHanging: The "Blurb" versions.
* LethallyStupid: Lumpy. Good god Lumpy. Remove this Lethal Moron from the show, and the death count will drop by half.
* LifeOrLimbDecision: Being one of the most horrific thing that could happen to someone, the episode "Out On A Limb" [[CrossesTheLineTwice of course makes a joke out of it]]. One of Lumpy's legs is trapped by a falling tree and he spends the next three days hacking his leg off. With a spoon. After finally finishing he finds [[spoiler: he cut off the wrong leg. And then the spoon breaks, so he has to use a paperclip.]]
** In ''Ski Ya, Wouldn't Wanna be Ya'', Flaky has to [[AgonyOfTheFeet stomp on a plank with a nail in it]] to use it as an improvised snowboard to escape from an avalanche.
* LudicrousGibs: Oh yes.
* MadeOfIron: Cro-Marmot, Flippy, Splendid, and Lumpy seem to be able to survive situations and wounds that would kill a normal tree friend (due to being entrapped in ice, serving in the military and being a FlyingBrick, respectively), making their deaths among the more gruesome ones in the show. In Lumpy's case, he is the tallest of the main cast, and with the exceptions of Splendid and possibly Evil Flippy, he is the strongest. In cases where Lumpy does not die immediately, he ends up getting injured.
** Pop and The Mole also seem to die somewhat less than other characters, although this can be attributed to luck more than anything else.
** Buddhist Monkey is not part of the regular cast; however, he can take far more punishment than the [[{{Mooks}} mooks]] [[MadeOfPlasticine he deals with]].
* MadeOfPlasticine: Somehow, tripping on a staircase is all it takes for Cuddles to be sliced in thirds.
** Pop once sliced Cub's scalp open with an electric hair trimmer.
** If you're one of the Friends, you'd want to think twice about being near an outward-opening door. Mole actually ''is'' killed by an opening door in "Home Is Where The Hurt Is".
** It gets turned UpToEleven with Nutty in "Swelter Skelter" and Sniffles in "Moppin' Up". Nutty gets tripped by Shifty and Sniffles trips in a pool of cleaning liquid. Their brains crack out of their heads. That's it.
** It pretty much depends on what makes for a more hilarious death. Apparently, a Christmas cookie, as seen in "Easy For You To Sleigh", is both soft enough to crumble into pieces upon hitting the floor and hard enough to ''carve through Shifty's ribcage.''
* MandatoryTwistEnding: In almost every episode at least one character dies horribly. Only a handful of episodes contain no deaths and in those, except for the five mentioned above, at least one character suffers grievous bodily harm.
* TheManyDeathsOfYou: Probably half the fun you'll get out of starting a new episode is wondering how many of the characters involved will be dead by the end, and from what.
* MeaningfulName: Everybody has one.
* MediumAwareness: The last segment of "Blast from the Past" re-creates the first official sketch, "Spin Fun Knowing Ya" (in which three of the characters die after being flung off a merry-go-round). Just before Cuddles flies off in this re-creation, he screams what sounds like "Oh my God! I'm gonna die! Not this old death again!"
* MindScrew: "Double Whammy".
** "A Bit of a Pickle".
** "Without A Hitch".
** "Blast From the Past".
* MoodWhiplash: Most episodes. They often end with a lingering shot of a scene of carnage, or a dead character, then a quick cut to the happy, bouncy theme music and colorful credits.
* NakedPeopleAreFunny: Giggles has seen Lumpy's privates in "You're Bakin' Me Crazy" after his towel drops, and in "Let It Slide" when his swimsuit comes off in the pool. [[note]]He's always wearing skin-tight shirts, as seen in You're Bakin' Me Crazy, but his typical lack of pants is best explained by HalfDressedCartoonAnimal[[/note]]
* NeatFreak: Petunia, particularly in later episodes.
* NegativeContinuity: The only way to keep the series going, or else everyone would be dead after about 5 episodes.
* NeverTrustAHairTonic: In "Easy Comb Easy Go", Disco Bear dunks his head in hair tonic after burning his afro. His hair grows back...but in his eyes. Cue EyeScream when he cuts his eyes off with a razor as he tries to remove the hair from his eyes.
* NeverTrustATrailer: The whole show is frequently marketed as an adorable kids' show about fluffy bunnies. Trailers are generally made out of the only thirty seconds of each episode that don't involve somebody getting gutted.
* NonSequitur: The {{aesop}}s, sometimes.
* NonstandardCharacterDesign: Lumpy.
* NoodleIncident: In the episode "A Change of Heart," an already dead and mangled Handy is shown in a pilot's outfit next to a dead and rather mutilated orca whale in the middle of a ''soccer field''. No explanation is given (which, to be honest, may be for the better).
* NothingIsScarier: Sometimes employed for an extra disturbing effect, such as the idol of ''"Treasure Those Idol Moments"'' appearing in Lumpy's car after it has caused every other character in contact with it to die horribly. The scene goes black after doing a closeup on the idol in the backseat, with the sound of an unseen car crash.
** The trope is also sometimes used to emphasize the already disturbing grievous injuries and deaths seen. ''"Nuttin' Wrong With Candy"'' features an already mangled Nutty getting threatened with EyeScream torture by the vending machine's metal coils and cuts to an outside shot of the fallen machine with blood pooling beneath it.
** In ''"Happy Trails Pt. 2: Jumping the Shark"'', we don't see what happens to Flaky, as it goes from the other characters glaring at her menacingly before the scene cuts to a sadistically laughing Flippy pounding a headstone into the ground while the other survivors leer from the shadows. The fact that this was the ''normal, sane'' Flippy does not help. And neither does the fact that her death was originally supposed to be onscreen, ''but was cut for being too gruesome.''
* NotTheFallThatKillsYou: Brutally averted in "Better Off Bread"; when [[IdiotHero Splendid]] catches a falling Giggles in midair, the impact snaps her spine in half. [[AndCallHimGeorge He obliviously carries her broken corpse around for most of the episode, and it becomes increasingly more mangled from his constant changes in velocity and high-speed flying.]]
* NutritionalNightmare: In one episode, a character enjoys several unhealthy foods in rapid succession, culminating in a deep fried block of butter; he has a heart attack, and in the hospital an X-ray reveals the undigested block of butter blocking one of his arteries.
* OffingTheOffspring: Many of Cub's deaths are due to negligence on Pop's behalf. However, in ''Read 'Em and Weep'', Pop intentionally kills Cub by beating him to death with a shovel, thinking he was still possessed.
* OffModel:
** The animators tend to forget that Toothy's buck teeth have a gap between them, instead drawing them like the other characters' buck teeth.
** Perhaps the most {{egregious}} is a scene in "Flippin' Burgers" where Cuddles' arms are attached ''to his cheeks'' for a couple seconds. How do you make a mistake like that?
* OffscreenMomentOfAwesome: The only time Flippy ever kills Lumpy (in "Keeping It Reel"), it happens off screen.
* OhCrap: For when death is imminent and the characters are well aware of it. Handy in particular gets an epic one in "Don't Yank My Chain."
* OmegaCast: Most of the time. Some exceptions include Generic Tree Friends and The Ants.
* TheOneWhoWearsShoes: Cuddles and Disco Bear.
* OneSteveLimit: Played straight so far, and we already have at least 25 named characters now. In addition to all of the differently named 20 main characters, there's also others such as Lammy, Truffles, Mr. Pickles, Buddhist Monkey, Sneaky, Moues Ka-Boom, Splendont, and a few others.
* OnlySaneMan: Flaky. Considering that, in the world of HTF, pretty much everything can and will kill you, Flaky is right to be scared all the time.
* PieEyed
* PrecisionFStrike: Lumpy gets one in ''Doggone It.''
** Flippy, too, in Autopsy Turvy.
* PressurePoint: The mysterious, faceless EvilOverlord, who keeps sending the ninjas after Buddhist Monkey, uses those to kill i.a. [[YouHaveFailedMe mooks who failed him]].
* PunnyName: Toothy, Lumpy, Nutty, [[SplitPersonality Flippy]], Handy, Flaky, Lammy, Lifty and Shifty.
* RealityEnsues: Anytime someone is killed by something that would do the exact same thing in real life.
** Several episodes feature comical devices or fantastic vehicles, such as the Driller with a bubble porthole in Hole Lotta Love. You'd expect the driller to dig a hole around the entirety of the vehicle, but it only digs a hole big enough for the body to go through, which unfortunately destroys the porthole and crushes Mole's head.
* RecordNeedleScratch: Occurs in [[http://www.youtube.com/watch?v=rU9Lp0TV_WU&feature=related this]] Christmas short and in "Ipso Fatso" when Disco Bear realizes he's fat.
* RedShirt: Sniffles and Mime become this figuratively and literally in ''Something Fishy.''
* ReedRichardsIsUseless: Sniffles, resident book worm and inventor, creates some rather useful inventions. Most of his creations backfire when being used by idiots. Although he sometimes tends to come up with incredibly overcomplicated solutions to simple problems, like building a DrillTank to rescue Cub from a well, despite the fact that a longer rope would have just as, if not more effective. Of course, he isn't immune to the IdiotBall, despite his intelligence. Sometimes borders on ScienceRelatedMemeticDisorder.
* ResetButton: ''Better Off Bread''.
* RoadRunnervsCoyote: Sniffles vs. the Ants.
* RougeAnglesOfSatin: In the opening credits of ''Swelter Skelter'', "Starring" is spelled "Staring".
* RuleOfFunny: The main explanation for some of the less logical deaths.
* SadistShow: How else can you describe it? Enjoyment essentially comes from watching a group of hapless woodland critters horribly burn, maim and torture themselves and each other.
* ScreamsLikeALittleGirl: Several characters. Funnily enough both Splendid and good Flippy.
* SeldomSeenSpecies: Cro-Marmot, who could possibly be the only fiction marmot in cartoon history (gophers are more common, though). Note that he never displays any marmot-like behavior. Or any behavior, for that matter.
* SelfDeprecation: In the "blurb" version of "We're Scrooged!", during a scene where Cuddles is playing with a robot, the blurb reads, "in the future, this robot will write better jokes than us!"
* SerialEscalation: Much of the gore, naturally, but the worst case is when Lumpy created such a huge display of lights for Christmas, that he not only set several characters on fire, but even ''The Mole'' had to shield his eyes.
* SeriousBusiness: ''Class Act'' is the subject of a great deal of debate in the fandom. Major points of dispute include whether or not Toothy was responsible for [[spoiler:the fire that burned down the school]], and whether or not [[spoiler:Splendid, Cro-Marmot and Flippy]] died in the explosion. For the latter, though, the answer was later confirmed as [[spoiler:yes.]]
* ShellShockedSenior: Flippy, who even has "triggers" that set him off, from the time that he fought in the W.A.R.
* ShootTheShaggyDog: Almost every episode, although some prominent examples are the depressingly hard to watch "Ski Ya, Wouldn't Wanna be Ya", where Flaky goes those a lot self-imposed pain just to survive, and "Double Whammy" wherein Flippy goes through a lot of trouble and has an epic battle with his demons, finally overcoming his PTSD...just in time to get roadkilled by a chicken truck.
* ShoutOut: Double Whammy is probably a huge reference to ''Film/FightClub.''
** Blatant one to Film/TheShining in the episode "Aw Shucks!" Lumpy is trying to get a crow out of his house, and the crow seeks refuge in his bathroom. Cue Lumpy (with ax in hand) breaking through the door, complete with a Simlish [[MemeticMutation "Heeerrrreee's Lumpy!"]]
** Splendid, an unashamed {{pastiche}} resp. parody of {{Superman}} as a character, once [[TimeTravel traveled back in time by flying around the Earth faster than light]] just like Superman did in the [[{{Film/Superman}} 1978 film]] to SetRightWhatOnceWentWrong, but not to prevent the several catastrophes he participated in in the original timeline, but to prevent the cake in his oven from scorching.
** Episode #55 (the halloween parody, where Pop buys Cub a cursed book, reads from it and Cub becomes possessed by [[EldritchAbomination something]],) is a blatant parody of TheExorcist.
** One early episode is called "Series/WhoseLineIsItAnyway".
** "Wrath of Con", being named after ''Film/StarTrekIITheWrathOfKhan'' and taking place at a con, would of course be packed with visual nods to other series:
*** Several people are dressed up; Giggles and Petunia as [[Franchise/StarWars Leia and an Ewok respectively]], Nutty as {{Franchise/Batman}}, a background character as [[{{ComicBook/Watchmen}} Rorschach]]...
*** The building which the episode takes place in was based on [[WesternAnimation/SuperFriends the Hall of Justice]].
** Speaking of Star Trek
* SingleTear: Giggles does this in "Helping Helps." when she sees that there's a massive tidal wave coming right at her and there's no escape.
* SneezeOfDoom: Giggles has one in the Valentine's Day Smoochie that blows her brains out the back of her head.
* SoundtrackDissonance: The series is scored using mostly happy and jaunty music typical of cutesy kids' shows. Even when the inevitable carnage occurs, the music remains upbeat, though it gets mixed in with upbeat {{ScareChord}}s whenever something gruesome occurs. It is quite jarring to say the least.
* SpeakingSimlish: They ''do'' speak English, it's just almost always rendered barely intelligible. Many times, you can make out actual words, without the consonants (see MediumAwareness above for one example).
** Nutty is an exception; most of the time, he just [[LaughingMad laughs madly]] or says "Ooooh!". The only time the audience gets to know what he's said is in "As You Wish" [[note]]Random Acts of Silence has him whispering something to Sniffles[[/note]]; "I wish I had a scrumptious lollipop!"
* SpecialEditionTitle: The ThemeTune was done in minor key on a Halloween episode.
* SpoofAesop
* StatusQuoIsGod: Despite the number of times that the main characters have been killed and the horrific ways in which this occurs, they'll always be alive and well by the next episode.
* StepfordSmiler: Flippy is Type C.
* SubvertedKidsShow: Given the hate mail the producers have received from angry parents, probably one of the most effective in this regard.
* SuddenAnatomy: The characters regularly go back and forth between having four-fingered hands and hands that look like oven mitts, even within an episode. They normally have featureless feet without toes, but Lumpy gained two large, hoof-like toes for one scene in "Every Litter Bit Hurts"...and then he was given three toes for a surfing scene in "Wipe Out".
* SugarApocalypse: Happens routinely."Class Act" has half of the forest critters die when the school they were watching a Christmas play in burns down. The other half dies when the school explodes.
* SugarBowl: Their tree town is very pretty and happy, a first world forest nation as it were. Pity it goes down in flames every fifth episode.
* SuperPoweredEvilSide: Flippy and his alternate personality subvert this - it turns out in "Double Whammy" that [[{{Badass}} Good Flippy is every bit as competent]].
* TeamDad: Lumpy usually fills the "adult" roles in many episodes, playing chaperones, drivers and whatnot. [[LethallyStupid Too bad for the other Tree Friends in his care]].
* TheUnintelligible: It's very hard to understand a lot of what most characters say, and while they do usually speak in English, it can take a few views to interpret it. This was probably because the show was originally an internet series.
* ThemeTuneCameo: The cast sings part of it in "A to Zoo."
** This also happens in ''Happy Trails - Part 1'' and ''Take a Hike''
* TheyKilledKenny: Entire cast. Except for Cro-Marmot, Evil Flippy, and Splendid, who rarely ever die in the series.
* ThreateningShark: The sharks that frequently show up in beach episodes or episodes involving the ocean.
* ThrowingTheDistraction: Sniffles throws a rock to escape The Crack in "Idol Curiosity".
* TomeOfEldritchLore: What causes the events of "Read 'Em and Weep".
* TongueOnTheFlagpole:
** In "Tongue Twister Trouble", Sniffles the anteater gets his tongue frozen to a lake after trying to eat an ant.
** In another episode, Giggles and Petunia get their lips frozen to Cro-Marmot's ice block after trying to kiss him.
* TongueTrauma:
** In Giggles' Valentine smoochie, she tries licking an envelope and gets a paper cut so severe that ''the tip of her tongue falls off''.
** A series of [[ColdBloodedTorture horrific things]] get inflicted onto Sniffles' tongue in "Crazy Ant-ics" and "Tongue in Cheek".
* TrademarkFavoriteFood: Mime is seen eating peanuts in several episodes (though he dies by choking on one in "Happy Trails"), and Lifty and Shifty are seen stealing meat several times. [[KarmicDeath Just before they become meat]].
* TreesIntoToothpicks: In one episode, Lumpy destroys an entire tree for one toothpick.
* TwistEnding: The characters are rarely killed by the most likely and obvious cause - all too often it's something else that causes it.
* UnexplainedRecovery: The characters die in every episode and inexplicably come back to life in the next.
* VagueAge: Used to the creators' advantage to depict characters as either children or adults, depending on the episode (Lumpy, Disco Bear, Flippy, Pop and Cub are excluded from this).
* VengefulVendingMachine: An episode has Nutty try to buy a candy bar from a vending machine, but it gets stuck. He [[MadeOfPlasticine manages to somehow rip his own arm off]] pulling on the stuck candy bar, before the machine falls on him and finishes him off gruesomely.
* VisualPun: The Mole has a mole on his face.
* VomitIndiscretionShot: Used a lot, most notably in the episode "Gems the Breaks".
** Its [[VomitDiscretionShot younger, more sensitive brother]] appears too, in the form of letting the camera stay focused on where the character's upper body was before it went down.
* WantonCrueltyToTheCommonComma: The episode "Whose Line Is It Anyway" is spelled "''Who's'' Line Is It Anyway" on the title card.
* WhamEpisode: The ending of the aptly titled ''Double Whammy'', where [[spoiler: Flippy is confronted by his evil self.]] Then ''Autopsy-Turvy'', [[spoiler: which turns out to really be ''Double Whammy: Part 2''.]] Then subverted, since it looks like it didn't effect the status quo after all.
* WholesomeCrossdresser: "Aw Shucks!" shows us [[http://img3.wikia.nocookie.net/__cb20140221155730/happytreefriends/images/3/3b/Wholesome_Crossdresser.png a photo with Lumpy dressed in a pink and somewhat frilly dress]] for a few seconds. Cro-Marmot also has done this, when he was playing dress-up with Cuddles and Toothy in "Double Whammy, Part 2".
* WhyDidItHaveToBeSnakes: While Flaky is a coward in general, she seems especially terrified of baby chicks for some reason. Though one can't blame her after "Take A Hike" where she accidentally kills a chick, and a bird snatches her up and uses her corpse for a new nest.
* WingdingEyes: Lumpy gets the dollar sign variation in ''We're Scrooged!'' [[RuleOfThree three times]]. On the third iteration, a dollar sign also appears on his tongue. Lampshaded in the "Blurb" version, where the blurb reads, "$ eyes is a sign of serious illness."
** Petunia gets the heart variation in ''I Nub You''.
** Mime gets the dollar sign variation in "Mime to Five," followed promptly by unicycles (he'd been wanting to raise money for one all episode).

* YawnAndReach: The Mole does this to Lumpy in ''Blind Date''. Lampshaded in the Blurb version.
** Nutty imagines doing this to the [[ItMakesJustAsMuchSenseInContext gumball machine]] [[CargoShip he's dating]] in ''Sucker for Love''.
* YouWannaGetSued?: Happy Tree Friends made a special ''[[Website/{{Youtube}} Youtube]]'' video about Copyright law that will appear when a user gets a copyright strike on Youtube and the user will be forced to watch the Happy Tree Friends Copyright video and take the trivia questions about Copyright. As the announcer would say "Even though Youtube is a free video sharing site, You can still get into serious trouble."
