2	[[caption-width-right:350:Yes, that's a Happy Tree Friend adventuring there. Yep, that [[MadeOfPlasticine extremely fragile]] Happy Tree Friend.]]
3	''Happy Tree Friends Adventures'' is a fangame based off the ''WebAnimation/HappyTreeFriends'' series created by a Polish Creator/{{Konami}} fan named [=Radel999=] (or [=HTFMegaman=]) from Website/DeviantArt.
4
5	The series involves the main cast of HTF as they have to rescue Giggles (now Allay as of ''2'') from Bowser (the main villain of the ''Franchise/SuperMarioBros'' series), and the game is a crossover with many famous video game franchises like ''Mario'' (the most of it), ''Franchise/MegaMan'', etc. and the gameplay is a style of... you guessed it, Creator/{{Konami}}'s NES games. The game is made in Multimedia Fusion 2/Clickteam Fusion 2.5 and the series was begun back in 2009, and plenty of sequels and spin-offs were made (in total of 11 as of 2017), many of them still being made or on hiatus. The list of the series' games are here:
6	* ''Happy Tree Friends Adventures'' (2009)
7	* ''Happy Tree Friends Adventures 2'' (2010)
8	* ''Happy Tree Friends Adventures 3'' (2010)
9	* ''Happy Tree Friends Adventures 4'' (2010)
10	* ''Happy Tree Friends Origins'' (2010): First spin-off centering around Lemy and Allay.
11	* ''Happy Tree Friends Adventures 5'' (2011)
12	* ''Happy Tree Friends Adventures 6'' (2011)
13	* ''Happy Tree Friends Adventures Game Boy'' (2012): Another spin-off and it is ExactlyWhatItSaysOnTheTin, it is a UsefulNotes/GameBoy-styled spin-off. Unlike ''Origins'', the standard six Happy Tree Friends are playable instead of [[OriginalCharacter fan characters]].
14	* ''Happy Tree Friends Adventures Land'' (2013): The third spin-off. Not only the standard six Happy Tree Friends are playable, but also Neena and Tacho, who are playable for the first time in this game.
15	* ''Happy Tree Friends Adventures Maker'' (2016): Basically ''WebAnimation/HappyTreeFriends'' meets ''VideoGame/SuperMarioMaker''.
16	* ''Happy Tree Friends Adventures RPG: The Fire Point'' (2017): The first and only RPG spinoff of HTFA. Made using RPG Maker VX Ace.
17
18	...and many, many more planned.
19
20	The downloads for these games were firstly uploaded on [=MegaUpload=] officially from [=Radel999=], but when it was shut down, many old HTFA games were lost in ashes, until somebody has recovered the games. Recently, the author himself has compiled all of the existing HTFA games along with his other game projects in [[https://www.mediafire.com/folder/y2m9gyh0w4lmf/Dunami_Projects a MediaFire folder]].
21
22	[=Radel999=] is on [[https://www.youtube.com/user/radel999 YouTube]] along with [[https://www.youtube.com/user/DunamiCoLtd/ his Dunami Co. Ltd. channel]] (most of ''6''- and ''Legends''- related videos go here and it was never been re-used since now), however, he appears more often [[http://htfmegaman.deviantart.com/ in DeviantART]], which he carries on a bunch of HTF fanart in decent HTF style. He even tried to make Bowser appear in HTF style too, but judging from his journals, HTFA is not the only series he made.

24	''Happy Tree Friends Adventures Maker'''s levels can be shared in its own version of ''Maker'' bookmark, a [=WordPress=] blog titled simply ''[[https://htfabookmark.wordpress.com/ Happy Tree Friends Adventures Bookmark]]''. Keep in mind that the site isn't managed by [=Radel999=] himself.

52	----
53	!! This game provides examples of:
54	* OneUp: Can be gained from either picking up extra life items or obtaining [[LawOfOneHundred 100 collectibles]] (the latter is limited to certain games).
55	* AbnormalAmmo: Most of the HTFA series' playable characters throw balls instead of just melee attacking.
56	** Some of the special powers can be this too. For example, Cuddles hurls a carrot.
57	* ActionGirl: Flaky, Petunia, Giggles, Neena and Allay (in HTF Origins).
58	* AdaptationalBadass: Bowser, and that's [=Radel999=]'s favourite character. He was notable for kidnapping Allay, allying with creepy aliens, and summoning his koopalings to try to end the heroes. He as well made [[spoiler:a giant mecha]] in HTFA 6 and he was once friends with the HTF villains.
59	** The Happy Tree Friends are given this treatment as well. They're usually known for being [[MadeOfPlasticine very fragile]] and die from even the slightest impact or the most mundane objects. Here, they can take several hits from ''any'' hazard (except for bottomless pits, poisonous bogs, and lava; they'll always die instantly from those hazards) before dying and are capable of taking down a huge army sent out by Bowser, which normally has enough power to kill them about a thousand times over or more if it's applied in the HTF universe.
60	* AdvancingWallOfDoom: A few levels in the series have one section or an entire level involving you being chased by something, usually in the form of DescendingCeiling.
61	** On the rarer instances, it's the "burning hot" version of RiseToTheChallenge instead.
62	** AdvancingBossOfDoom: In HTF Origins, a [[VideoGame/{{Shinobi}} Godzilla-lookalike]] creature chases you when you first encountered him. You can't damage him at all until you're back at the pyramid's entrance, at which point he falls into a conveniently-placed lava pool.
63	* AirborneMook: There are several enemies that are classified as this.
64	* AmbidextrousSprite: More noticeable on certain characters, like Nutty (his candy accessories switch places depending on where he's facing, same goes for his eyes).
65	** For Nutty's case, it's averted in HTFA GB. Depending on which side he's facing, you can either see his normal eye (with black pupil) or his googly one (colored).
66	* AntiFrustrationFeatures: Since HTFA 2, it has konami-style passwords as saves, until HTFA 6, it now provides a softer save data system.
67	* ArtEvolution: [[http://fc07.deviantart.net/fs71/f/2011/295/1/2/htfa___history_of_sprites_by_radel999-d4dle0k.png This picture explains it all, with the example of Cuddles.]] HTFA 1 to 4's sprites didn't look bad (keep in mind that those sprites (the playable ones) are taken from ''Blood Money'' (more specifically, basing the sprites off of Cuddles), a HTF mobile game), while in HTFA 5, it switched to a more retro-ish style, until HTFA 6 and its present games' sprites soon were made in Flash and resized into actual sprites.
68	** The HTFA 6 to now sprites look like decently from the HTF series.
69	* AscendedExtra: Giggles was a DamselInDistress and Toothy was a minor NPC in HTFA 1. Starting from HTFA 2, both became a prominent part of the playable cast.
70	* AuthorAppeal: The reason why Bowser mostly appears in every HTFA game is because Radel's favourite character of all time was Bowser, also he made a contra fan game depicting Bowser in the place of Bill Rizer, and the name of the game is ''Bowser the Warrior''.
71	* AutoSave: Used in HTFA Land.
72	* AutoscrollingLevel: Several final stages of the games tend to have these.
73	* BadassAdorable: The playable HTF characters. See the AdaptationalBadass section above for more explanation.
74	* BigBad: Bowser.
75	* BigBoosHaunt: The "undead"-themed levels.
76	* BigDamnHeroes:
77	** Toothy in HTFA 1, who has his spaceship ready to pick up the heroes and [[DamselInDistress Giggles]] while Bowser's lair is collapsing.
78	** [[Franchise/SuperMarioBros The winged Yoshi]] in HTFA 3, who manages to save the heroes and [[DamselInDistress Allay]] from falling to their doom after Bowser's ship self-destructed.
79	* BigFancyCastle: The castle levels.
80	* BlandNameProduct: The company that made the series is named Dunami. The logo symbol hints it's based off Konami's old logo.
81	* BlindIdiotTranslation: [=Radel999=] is Polish and his English isn't very good, so the games serve many typos from his Engrish.
82	** In the credits, we can see a noticeable typo as "Sound/Graphics/etc. Desinger" instead of "Designer".
83	* BlowYouAway: Brandy's Special Power, which involves him shooting mini-twisters.
84	* BossOnlyLevel: In HTFA 5, the final level of a kingdom only consists of a boss fight.
85	* BossRoom: Most boss levels (especially [[BossOnlyLevel boss-only levels]]) take place in a single room.
86	* BossRush: Most of the HTFA games have the previous bosses you fought before the final stage.
87	* BubblegloopSwamp: Not really commonplace in this series. If there's one, it usually has pools of poisonous bog that can instantly kill you if you fall in.
88	* BuildLikeAnEgyptian: The pyramid levels.
89	* CaptainErsatz: Look at those cute Rainbow Critters/Furries in HTFA Land... wait, what do you mean they're simply [[VideoGame/KirbySqueakSquad Squeakers]] with feet and different facial features?!
90	* CharacterPortrait: Used in conversations in HTFA 5 and ''Origins''.
91	* CheckPoint:
92	** In HTFA games with "long" levels (span multiple screens), checkpoints are placed after a screen change so if you die you end up continuing from the level segment you currently ended up instead of starting from the very beginning of the level.
93	** "Save game"-wise, HTFA 3 and 5 have their own checkpoints in the form of PasswordSave being available per world/kingdom due to the levels in those worlds/kingdoms being shorter.
94	* CheckpointStarvation: The first HTFA game didn't have a password system, and it will be a pain to start over if you get a game over, same goes for HTFA GB.
95	** HTFA Land might as well suffer from this, due to having an infamous GameBreakingBug regarding game saves.
96	* ClassicCheatCode: In HTFA 2, after you beat the game, [[spoiler:the credits gives you a ninfty cheat code to access the hidden menu, including all the levels and the secret Flippy boss fight]]. The shortcut is [[spoiler:Shift+Ctrl+Spacebar]].
97	** KonamiCode:In HTFA Land, it is even actually possible to do it so, [[spoiler:it will give you 30 lives just like in the {{VideoGame/Contra}} series]].
98	* ClimaxBoss: [[spoiler:Tiger General]] in HTFA 6, he's like Cossack from the ''Franchise/MegaMan'' series and he's [[spoiler:the final boss of his fortress]], surprisingly, [[spoiler:he has one of the mechas from the series too, ready to smash you]].
99	* ColourCodedForYourConvenience: In HTFA 1 and HTFA Land, each character's HUD has its own color.
100	* ContinuingIsPainful: In HTFA games that feature long levels (that spans multiple "screen" changes), if you die you have to start over from a checkpoint (which is placed after a "screen" change). '''Not so''' if you get a GameOver instead, where if you choose to continue, you start the level ALL over again. Hurts more if the level is incredibly difficult and you often lost many lives there. Hurts even, EVEN more if the level ends with a difficult BossBattle.
101	** This can also apply to short levels, provided if the level is nearing PlatformHell status.
102	** Even if you've taken notes on passwords for the earlier HTFA games, if you choose to use them to immediately access a later level, unless you're really skilled, you will possibly end up getting a GameOver early, as the game will always set the same initial number of lives (if you can't adjust them) every time it's booted.
103	** HTFA 3 and 5 can feel like this if you have to quit before you finish your playthrough. Sure the games use PasswordSave, but a password is given per ''world/kingdom'', not level. So, if you decided to take a break by quitting one of those games, you have to begin from the first level of a world/kingdom again if the password is used. It sure hurts for you to start a world/kingdom over if you were at the world's/kingdom's penultimate level or at its boss level prior to closing the game.
104	* ConvectionSchmonvection
105	* ConvenientWeaknessPlacement: Boss battles involving Wheel Gator always have some kind of water containment that can be spilled via either a convenient flashing spot (in HTFA 2) or huge buttons on each side (in HTFA Land).
106	* CriticalExistenceFailure: The Happy Tree Friends still look fine even after taking so much damage they're down to 1 hit point. Get hit at that critical state, then he/she will either explode into LudicrousGibs, end up brutally wounded, or collapse.
107	* CrossOver: This game mostly cross-overs with ''Franchise/SuperMarioBros'' due to Bowser being the main villain and is responsible for summoning his minions (including his Koopalings).
108	** The later games also deal with ''VideoGame/{{Contra}}'', ''Franchise/MegaMan'', ''VideoGame/AdventureIsland'', and some other franchises from the NES and from Konami.
109	** Not to mention that VideoGame/TwinBee (as well as [=WinBee=]) also appear in this game as the heroes' spaceship/submarine.
110	** From the HTF's Ka-Pow! series, [[spoiler:Tiger General]] also appears in HTF Origins [[spoiler:as one of the bosses]] and HTFA 6 [[spoiler:as the final boss of Tiger General's fortress]].
111	** [[spoiler:From the [[Anime/DigimonAdventure Digimon]] universe, the game also includes Izzy, who is playable in HTFA 6. For some reason, he appears in HTF form.]]
112	* CueTheSun: The credits roll of HTFA 2 shows the protagonists and Allay standing while the sun slowly rises.
113	* DarkerAndEdgier: The final moments of every HTFA game, it can be either [[spoiler:a (space) fortress full of minions ready to attack you and/or a alien lair]].
114	* ADayInTheLimelight: In most HTFA games, Allay is often present in her princess form and end up being kidnapped by Bowser. In HTF Origins, you can finally get to play as her (if you choose to play as her anyway), albeit in her normal "yellow bear" look.
115	* DeathIsASlapOnTheWrist: In a few HTFA games, other than the ones that have ContinuingIsPainful applied to them, getting a GameOver is more or less a minor annoyance (that is, if you're still allowed to continue... and you're not running out of continues (in certain games) as well).
116	* DeathMountain: The mountain levels.
117	* DeathThrows: Used starting from HTFA 2. In HTFA 1, the playable characters simply [[LudicrousGibs explode into blood and gore]] upon death.
118	* DefeatMeansPlayable: Only applied to Brandy in HTFA 6.
119	* DegradedBoss: The boss from the Volcanic Jungle level in HTF Origins. Actually, it's applied to his machine. The {{Mook}} version of those machines are smaller and easier to destroy.
120	* DemotedToExtra: Lemy. He only got one major role, and that's in a spinoff. After that, he ends up being an NPC that only appears in cutscenes in HTFA 5.
121	* DenialOfDiagonalAttack: In HTFA games with the more stable engine, the Happy Tree Friends can only fire horizontally. Averted in the first three games, only if you involve some jumping, and even then it's still difficult to ''actually'' fire diagonally (and they're mostly fired downwards).
122	* DramaticThunder: HTFA 6 has one during the Castle intros.
123	* EarlyInstallmentWeirdness:
124	** Comparing HTFA 1 with the next games can be quite jarring. In HTFA 1:
125	*** There are only four characters you can pick. Future games usually stick with the standard six plus a few other characters if necessary, with HTF Origins being the only exception.
126	*** Instead of a fan character, a canon character (Giggles) is the DamselInDistress.
127	*** You start with three health points, but you can increase the amount by picking up Hearts (up to around 16), unlike the other games where you'll always start with the maximum amount of health.
128	*** The game mechanics and physics are the most broken out of all HTFA games. It's Radel's one of the earliest projects, and it shows.
129	*** The character's HUD is located on the bottom instead on the top part of the screen. (the only later HTFA title to have this is HTFA GB)
130	*** You cannot kill Cheep-Cheeps.
131	*** The cast can be considered minimalist compared to the future games. For one thing, no HTF fan characters appear. Second, bosses are mainly taken from ''Franchise/SuperMarioBros universe. Other non-SMB and non-HTF characters are considered lacking in variety.
132	*** It's the only HTFA game to depict Bowser's [[FamilyUnfriendlyDeath graphic]] [[YourHeadASplode death]] on-screen after you defeat him for the final time in said game. Other HTFA games either depict his base/lair destroyed/collapsed with him still inside or have him escape from said destruction.
133	*** There are no dialogues whatsoever. Characters began speaking starting from HTFA 2.
134	** When it comes to spinoffs, the very first one, HTF Origins, is weird in its own way for having only two playable characters, and both are fan characters, no official HTF characters. It's also the only game so far where you get to interact with a NPC in-level (not counting the intro one, the intermission (between levels) ones and the pre-boss battle ones). As for the game's character cast, ''Origins'' has loads of characters (especially due to the fact that the kidnapped Happy Tree Friends are also shown on-screen) compared to the more "minimalist" cast in HTFA GB and HTFA Land.
135	* EarWings: The rainbow critters have large ears allowing them to fly.
136	* EdibleCollectible: [[PowerUpFood Candies]], fruits, etc.
137	* EnergyWeapon: For his Special Power, [[spoiler:Izzy carries a RayGun that he can use to shoot laser, probably to make up for the fact that his Digimon partner doesn't appear in the series]].
138	* EscapeSequence: There's one in HTF Origins where you have to run away from a [[VideoGame/{{Shinobi}} Godzilla-lookalike]] after going to the deepest part of the pyramid in [[ShiftingSandLand Desert of Koopa]]. The way it's implemented, however, looks more like a glorified AutoScrollingLevel.
139	* EternalEngine: More noticable in HTFA 6, where its fortress levels are basically this, what with the machinery being almost everywhere there.
140	* [[EveryoneHasASpecialMove Every Playable Character Has A Special Move]]: The playable characters' Special Powers, which are featured starting from HTFA 6, except for HTFA GB.
141	* EverythingsBetterWithRainbows: The Rainbow Critters and their kingdom in HTFA Land.
142	* ExcusePlot: The main HTFA series' plots are like this, when Giggles/Allay gets kidnapped by Bowser, except in HTF Origins and HTFA Land.
143	* ExplosionsInSpace: Seeing that most final boss battles take place in a base located in the outer space, this trope tends to happen.
144	* FakeDifficulty: For the earlier games, most of the difficulty is actually caused by the troublesome game mechanics and controls.
145	* FanSequel: Somebody (or certainly the creator of this page) attempted once to make a fangame out of this series named Happy Tree Friends Adventures Reborn. It has a different storyline, other characters that didn't appear in the series, and even it was planned to have a really long game length of stages, but there was a word of god from the creator that it was cancelled due to lack of ideas and possibly moving on to other projects.
146	* FightingYourFriend: Brandy in HTFA 6 as one of the first 7 bosses, many players find it out he was brainwashed.
147	* FinalBossPreview: In HTFA 2, the 6th stage's boss is Bowser along with an creepy looking alien head from Wai Wai World, which is then also fought in the final stage.
148	* FlashOfPain: Depending on the game and boss.
149	* FloatingPlatforms
150	* [[FollowTheMoney Follow The Jewels/Gems]]
151	* GameBreakingBug
152	** In most HTFA games, if your computer isn't fast enough, stage elements (particularly moving platforms and certain bosses) may behave strangely and can cause {{Unwinnable}} condition.
153	** HTFA Land's notable flaw is its tendency to crash when loading a saved game. Other times, the save game can be loaded, but rendered useless after a few levels as it will end up crashing anyway.
154	** In HTFA 6, a somewhat rare glitch can cause your character to get stuck in swimming sections where the passage (vertical only) is as wide as your character. "Wide", as in being as wide as the characters with large tail, which there are 5 of them (out of 8).
155	** HTFA Maker has one where if you place the [[LevelGoal flag]] on brick tiles (and no other tiles of a different kind), the Bowser flag and your character will go down indefinitely, necessitating a fix.
156	* GameOverMan:
157	** HTFA 1 has Bowser standing in the background while all four protagonists fall into spikes when you get a game over. "YOU MUST DIE"
158	** In HTFA 6, the game over screen features Bowser once again, who [[OffWithHisHead has decapitated Cuddles and Giggles]].
159	** HTFA Land depicts Bowser flying in his Clown Car in the game over screen.
160	* GameplayAllyImmortality: HTFA 4's fourth level and one level in HTFA 5 have Neena carry you across the sea via water-skiing. In both cases, Neena can't be harmed and can pass through obstacles just fine (even despite the latter case having Neena semi-controllable by allowing her to jump along with the player).
161	* GangplankGalleon: The ship levels.
162	* TheGoomba:
163	** From the first four games, the ''unarmed'' Hammer Bros take this role. They are common enemies that walk back and forth, only dealing damage via CollisionDamage, and die in one hit.
164	** In HTF Origins and HTFA 5-6, green Koopa Troopas are this. They're also this in HTFA GB, too, even though it marked the debut of a ''Goomba'' (albeit its subspecies, the Paragoomba), thanks to the latter being less common than the former.
165	** Only starting from HTFA Land do the proper Goombas appear and take this role.
166	* GoombaStomp: In HTF Origins and HTFA Land, you can have chance to stomp several enemies.
167	* GreenHillZone: The first levels of each game tend to be this.
168	* GuestFighter: A non-FightingGame example. [[spoiler:[[Anime/DigimonAdventure Izzy]] appears as a playable character in HTFA 6, albeit in HTF form]].
169	* HappyEndingOverride: The introductory cutscene in HTFA 5 shows the ending of HTFA 4 (where the heroes managed to escape Bowser's space station that was in the middle of blowing up), but later on it's revealed that Bowser somehow hitched a ride inside a meteorite(?!) which crashed not far where Allay lives. Bowser then immediately kidnapped Allay once again.
170	* HardLevelsEasyBosses: Applied to the first HTFA. The levels tend to be hard due to the broken physics and the near-lack of MercyInvincibility, while every boss except the last one is actually very easy to beat.
171	* HeadSwap: Notable examples include the majority of the Koopa Masters in HTFA 6, with half of its members being simply [[Franchise/MegaMan Robot Masters]] with [[Franchise/SuperMarioBros Koopa heads]] and the Robo Koopa in HTFA GB, who is basically a ''VideoGame/BionicCommando'' boss with a Koopa head.
172	** For an enemy example, the Koopa Muscler in HTFA 6. From the name alone, [=Radel999=] didn't even try to hide the fact that it's [[VideoGame/MegaMan5 Power Muscler]] with a Bowser-like face.
173	* HealingCheckpoint: Each time you get in the next part of a level, your health seems to be recovered.
174	* HeartsAreHealth
175	* HeavilyArmoredMook: In later levels of HTFA 4, you can find [[PaletteSwap gray Hammer Bros]] that stop you on your tracks and force you to fight against them. Unlike regular Hammer Bros and Fire Bros, they take multiple hits before losing their "armor" and reverting back to a normal Hammer Bro. Their only means of attacking is throwing hammers which burst into flame sparks when they hit the ground. You can even encounter more than one in the same fight, but the group can take similar punishment as a lone one as if they have a shared health bar.
176	* HyperspaceArsenal: One must wonder where those tree friends keep the balls/orbs/Special Power-based objects for their projectile weapon. This is the only answer, since they all have an infinite supply of balls/orbs/Special Power weapons.
177	* IconicSequelCharacter: Neena and Tacho were introduced in HTFA 4. Both of them are now as iconic as the six main characters, even becoming playable in HTFA Land. Not convinced enough? Take a look at Radel's Website/DeviantArt gallery and favorites. Especially his favorites. Whenever he's requesting for a fanart, he usually mentions the two fan characters, along with his own.
178	* ImmediateSequel: See the HappyEndingOverride section.
179	* ImprobableWeaponUser: For an example, Cuddles uses carrots as weapon, which can also somehow break fragile walls.
180	* InASingleBound: Flaky's most recent Special Power invokes this.
181	* InescapableAmbush: Later levels of HTFA 4 have certain sections where you can't go back or progress further unless you defeat all (as in, remove the armor) of the armored Hammer Bros.
182	* InNameOnly: Starting from HTFA Maker onwards (though [[OlderThanTheyThink HTFA GB started it first]]), the series has become "''WebAnimation/HappyTreeFriends'' InNameOnly" because of [=HTFMegaman=]'s plan of removing all blood and gore in the later games. For those who haven't watched the HTF show, it's well-known for blood and gore applied to adorable critters as part of its BlackComedy purpose, so removing them while still keeping the canon characters in the cast (albeit changed according to [=HTFMegaman=]'s liking) will result in this trope.
183	* Instant180DegreeTurn
184	* InterfaceSpoiler: If you've watched the ''W.A.R. Journal'' short, this should hint you [[spoiler:that the first fortress you're going to actually belongs to Tiger General]], thanks to the yellow symbol on the fortress.
185	* InvincibilityPowerUp: Only in HTF Origins. Plays the {{VideoGame/Bomberman}} music when picked up.
186	* KidHero: Despite their vague age in canon, the playable cast is this, thanks to the creator making up their ages (the six standard playable characters are 9 according to him; other playable characters tend to be older).
187	* LaResistance: The heroes are a team of cute animals and there are 8 of them as of the current HTFA games.
188	* LaterInstallmentWeirdness: HTFA Maker is the first HTFA game published after [=Radel999=]'s confirmation regarding the removal of blood and gore from the later entries in the series (though [[OlderThanTheyThink HTFA GB already did it first]]; meanwhile, the still beta HTFA RPG was actually developed prior to said announcement). Considering this is still ''WebAnimation/HappyTreeFriends'' fanwork, the weirdness of this later title is noticeable.
189	** Organic enemies now explode in a puff of smoke (in [[{{Retraux}} HTFA GB]], they simply explode without any blood) instead of blood and gore. Even the Happy Tree Friends don't bleed anymore when they get damaged by enemies/hazards.
190	** The rather-jarring voice change applied to some of the playable characters. Flaky, Petunia, Nutty and Giggles's voice actors have been changed for HTFA Maker, and when compared to previous voice actors and the original show's voices, the only conclusion that can be made is the fact that the four characters' voices end up being way too high-pitched compared to their original voices. Keep in mind that the previous voice actors actually ''tried'' to emulate their original voice, even if it's slightly off. In HTFA Maker, they end up sounding way off from how they originally sound in the show, with Flaky and Petunia suffering the worst (not only being way too high-pitched, but when speaking, they ''don't sound like themselves at all''). Nutty's new voice actor at least tried to emulate his laughs and Giggles's new voice sounds a little bit closer to how Lori Jee would voice her in the later seasons of the HTF show (albeit, once again, being more high-pitched).
191	* LavaPit: A common hazard in the series. Often found in caves and Bowser's territory.
192	* LawOfOneHundred: In certain games, collecting 100 collectibles (usually valuables like jewels and gems) will reward you with an extra life.
193	* LeapOfFaith: The "Game Boy"-styled spinoff is the worst offender. Due to the "zoomed-in" look, whenever you come across what seems to be a huge gap, you might be unsure whether to jump down or not, as more often than not, a bottomless pit is ''indeed'' a bottomless pit. Few of these cases are usually accompanied by an arrow pointing down, but why those arrows aren't used on other places is never known. Another way to check for safety is to see if there are visible, on-ground enemies walking by. If there are no other clues, you may as well try jumping down and hope you land on solid ground.
194	* LethalLavaLand: Many final stages have these, serving as Bowser's homes.
195	* LevelAte: There's one level in HTFA 4 which is made up of cakes.
196	* LevelEditor: The whole point of HTFA Maker.
197	* LevelGoal: The ''VideoGame/SuperMarioWorld'' gates in HTFA 1, the "GOAL" sign in HTFA 3, defeating [[Franchise/SuperMarioBros Birdo]] in HTFA 5, and the ''VideoGame/SuperMarioBros1''-esque flagpole in HTFA Land and ''Maker''.
198	* LevelsTakeFlight: In HTFA 2, there's one level where you ride either [=TwinBee=] or [=WinBee=] to go to the outer space.
199	* LifeMeter: Its appearance and amount of hit points contained depend on game. HTFA GB has the shortest LifeMeter with only 5 hit points at max.
200	* LiftOfDoom: A few levels contain this gimmick. The ''reverse'' version, as in it moves down instead of rising up, can be found in the second level of HTFA 4.
201	* LighterAndSofter: Overall, the series feels like this. You go from the earlier titles, which often involve abominations like the ones from ''VideoGame/{{Contra}}'' and, for the ''Origins'' spinoff, a dark plot, to the more fantasy-esque HTFA 5, then take a little dip to the DarkerAndEdgier HTFA 6, then come back out with the less dark HTFA GB and the more colorful and closer to ''Franchise/SuperMarioBros'' HTFA game, HTFA Land (though it has one level based on the DarkerAndEdgier near-endgame levels in early HTFA games). Now it's confirmed via WordOfGod that the fangame series will lack blood and gore (as well as horrible injuries) that the HTF show is known for, starting from HTFA Maker (though [[OlderThanTheyThink HTFA GB started it first]]).
202	* LuckBasedMission: In HTFA 4, the boss battle against Ludwig is this. His machine fires one bullet per shot, but there is no exact pattern of where the bullet will be shot to. So, the player can either avoid many of his bullets easily without losing a life, finally defeat him after losing several lives, or getting a game over often.
203	* LudicrousGibs: Each enemy you kill explodes into a gorefest just like seen in Happy Tree Friends' episodes. Averted in [[{{Retraux}} HTFA GB]] and the later games starting from HTFA Maker, as confirmed by WordOfGod.
204	* MakingASplash: Toothy's Special Power, which involves him ''shooting his own tears''.
205	* MeaninglessLives: In games where lives can be easily replenished by picking up enough collectibles (in addition to the usual extra life pick-ups), it's hard to run out of lives unless you do so deliberately. Especially noticeable in HTFA Land, where every time you die, the number of gems collected simply resets back to the amount when you first begin the level, thus allowing you to recover your previously-lost life easily by recollecting the gems again.
206	** In HTFA 2, you can simply farm lives [[spoiler:from the boss battle against [[OptionalBoss Flippy]], which will always give you 20 extra lives after defeating him]]. Considering that a session can be done in roughly 2 minutes, this makes the whole life-farming in this game a borderline GameBreaker.
207	* MegaCrossover: See CrossOver above.
208	* MusicalNod: The series' music come from many well-known NES games from popular franchises and several Konami games.
209	* NewWorkRecycledGraphics:
210	** Three HTFA games after the first often re-use character sprites from the first. In turn, several graphical elements from HTFA 2 (like the HUD) had their graphics re-used in HTFA 3 and 4. Meanwhile, the polished Happy Tree Friends sprites are re-used in HTF Origins.
211	** Enemy graphics used in HTFA 5 are then mostly re-used in HTFA 6.
212	* NightOfTheLivingMooks: In haunted/ghostly-themed levels, you can encounter this type of {{Mook}}.
213	* NostalgiaLevel: One fan managed to re-create the first level from HTFA 1 in HTFA Maker. Load up your own HTFA Maker app and load [[https://www.dropbox.com/s/58yj8ohxgf2krej/HTFA1%201-1%20v3.arr?dl=0 this level]] to check it out.
214	* NotTheIntendedUse: The password system in the HTFA games that use them. It's intended to be a PasswordSave system, but due to how the password system works (and the fact that the passwords are never randomized per level/world), once a player discovers and remembers a given password, that player can simply enter said password to warp to a later level. Having trouble with a level in your current run? Skip to another, provided you know the password. You can also warp to an earlier, easier level if you want to farm extra lives. If you've discovered a password for the final level? Just warp to said level, provided you're able to handle the final boss (and BossRush sections if any). This can result in some HTFA games lasting only a few minutes because of this exploit. [[DownplayedTrope Downplayed]] in HTFA 3 and 5, where using a password will warp you to the first level of a given world instead of on any level. But still, nothing stops you from warping to the final world, once again provided you can handle the later levels and boss battle(s).
215	** This may be the reason why HTFA 6 and the ''Land'' spin-off use the regular save system ([[{{Retraux}} HTFA GB]] lacking a save system is intentional in order to emulate the limitations of UsefulNotes/GameBoy games), though the latter game may as well lack any due to a GameBreakingBug.
216	* NumberedSequels
217	* OfficiallyShortenedTitle: Radel himself doesn't mind calling the series' title "HTF Adventures" or simply HTFA.
218	* OneHitPolykill: Some Special Powers can result in this if you fire a single shot to a group of weak enemies.
219	* OneSteveLimit:
220	** The limit is a bit broken notably in HTFA 6 where there are two instances where the name [[PlayingWithFire Fire Koopa]] is used: one for the [[{{Mook}} regular enemies]] that spew fireballs as their attack (and they have a winged/"para" variant) and one for the [[BossBattle early-game boss]].
221	** For this series in general, there's [[OriginalCharacter Lemy]] the lemur and [[Franchise/SuperMarioBros Lemmy]] the Koopaling.
222	* OneWingedAngel: In some HTFA games, Bowser [[spoiler:grows up in his giant size for his 2nd form from something like a spell]].
223	** In HTFA 6, instead, [[spoiler:he uses his giant mecha looking like himself in the final battle against him]].
224	* OptionalBoss: [[spoiler:Flippy]] in HTFA 2 can be only fought [[spoiler:by accessing in a hidden level select screen]].
225	* PalmtreePanic: The beach levels.
226	* PasswordSave: Used in the all HTFA games prior to HTFA 6, except for the first game.
227	* PeopleJars: One example can be found in HTFA Land. In the level "Fake Bowser Clone Laboratory", there are several jars filled with the still-developing Fake Bowsers that litter the place.
228	* UsefulNotes/{{Plagiarism}}: This fan game series is notorious for re-using assets (graphics and music) from already existing games. So much that the original content is very little to none. While Radel did give credit to some of the asset creators, there are still several (mostly music and unique sound effects) that went by uncredited (so this issue still counts), and thus making the already horrible series (yet [[SoBadItsGood still charming in a different way]]) even more horrible. In fact, this is one of the main criticisms pointed at the series, along with the premise.
229	* PlayingWithFire: Common attacks used by most enemies and bosses. Also, Tacho's Special Power.
230	* PlotCoupon: The keys in HTF Origins. They're required to access Bowser's empire.
231	** The diamonds in HTFA GB. They can only be gained from bosses (except in the last level) and function simply as a proof that you've beaten a level.
232	** PlotCouponThatDoesSomething: The red orbs that are gained from defeating the first seven bosses in HTFA 6. They're actually required to access the first fortress, but as [[spoiler:Izzy]] stated, the orbs also contain a hidden power that grants the Happy Tree Friends (and [[spoiler:Izzy]] himself) a special ability each. These special abilities are part of the Special Power mechanic in-game, where a button (by default, Spacebar) can be used to utilize that power and a new type of item pretty much refills the secondary gauge underneath the character's lifebar. The Special Power mechanic even extends to the future HTFA games (except for HTFA GB).
233	* PostEndGameContent: In HTFA 2 and HTFA Land, you will be hinted a cheat code in the credits, see ClassicCheatCode and KonamiCode above.
234	* PromotedToPlayable: Brandy becomes playable when you beat him in HTFA 6, while [[spoiler:Izzy]] is later unlocked after beating all the first bosses.
235	** Neena and Tacho spend most of their time as {{NPC}}s. They're now playable in HTFA Land.
236	* PutOnABus: The Koopalings haven't made another appearance since HTFA 4.
237	* QuicksandSucks: The desert levels tend to have this.
238	* RatchetScrolling: Thankfully none in most levels, but vertical levels tend to have this when it's not about RiseToTheChallenge or DescendingCeiling...
239	* RecycledSoundtrack: The games mostly use music from many games, see MusicalNod above.
240	* RemilitarizedZone: Most notably, later levels of HTF Origins have this feel.
241	* ReTraux: The games tend to be in NES style and it's based off Konami's NES games, unlike the graphics, they're not 8-bit that much.
242	** HTFA GB is actually in Game Boy style.
243	* RuinsForRuinsSake: The levels taking place in the ruins. It's never explained why those ruins are present.
244	* TheRuinsICaused: Some HTFA games show a shot of Bowser's lair collapsing into debris after the final battle.
245	* SavePoint: HTFA 6 gives you a choice whether to save your progress or not after a level.
246	* SaveThePrincess: The typical plot for most HTFA games.
247	* ScoreScreen: In certain games.
248	* ScrollingText: HTFA 4 uses this in cutscenes.
249	* SecondaryFire: Most special powers tend to have this trait.
250	* SecretLevel: There's one in HTFA 2. [[spoiler:It merely consists of a boss fight against [[OptionalBoss Flippy]], where beating him gives you 20 extra lives to start your adventure with.]]
251	* SequentialBoss: Some HTFA games have the final boss battles being this.
252	** The final boss battle in HTFA 2 has you fight Bowser and his [[VideoGame/WaiWaiWorld alien]] pet once again (first encountered in that game's sixth level), then you end up fighting [[MakeMyMonsterGrow a gigantic version of Bowser]] once the first round was finished.
253	** In HTFA 3, you fight Shi-vai first before fighting Bowser himself. [[spoiler:After finally defeating the latter, the battle isn't finished yet. One last battle pits you against Giga Bowser.]]
254	** HTFA 4 has you fight Bowser twice in the same room (albeit with different boss strategies). The battle after those two has you fight the gigantic Bowser once again.
255	** HTFA 6 has you fight Bowser's mech. After depleting the health of said mech, its head part flies off and reveals Bowser riding said head part like a flying vehicle, and you have to battle him in that state before the game can end properly.
256	** HTF Origins has a one-on-one fight against Bowser in the end of the final level. After that, Bowser makes a comeback by riding a mech.
257	** [[{{Retraux}} HTFA GB]] has you go through a BossRush before facing a mech shaped like Bowser's head. Defeating it allows you to have a proper battle against Bowser himself.
258	** HTFA Land's final boss battle is divided into two rounds. The first is ridiculously easy, being a throwback to ''[[VideoGame/SuperMarioBros1 Super Mario Bros.]]'' boss battles. The second one, however... let's just say that if the game messes up, get ready to start over.[[note]]HTFA Land, despite [[{{Autosave}} autosaving]] your progress, is very likely to crash whenever you decided to reload your save. Why this is highly concerned is because occasionally the game [[GameBreakingBug glitches in a way that causes the gigantic Bowser to leap off-screen and never come back]], which will cause you to reload.[[/note]]
259	* ShiftingSandLand: The desert levels.
260	* ShockwaveStomp: Used by [[VideoGame/WarioLand Spiked Pirate]] in [[{{Retraux}} HTFA GB]].
261	* ShoutOut:
262	** The games are homage to the classic NES games such as the [[WesternAnimation/TinyToonAdventures Tiny Toon Adventures]] game series, [[AdventureIsland Adventure Island]] and ''Franchise/MegaMan''.
263	** Flaky's [[RollingAttack Special Power]] in HTFA 6 is basically [[VideoGame/SonicTheHedgehog Sonic's Spin Dash]].
264	** This [[http://htfmegaman.deviantart.com/art/Happy-Tree-Friends-Adventures-World-Wallpaper-502060979 promotional wallpaper]] for HTFA World is a ShoutOut to [[http://www.ssbwiki.com/File:Mega_Man_Poster.jpg this Super Smash Bros. poster]]. It even has Bowser in the background (with the same pose to boot!) and Cuddles mimicking Mega Man's pose.
265	** In HTFA 6, [[VideoGame/YoshisIsland Cub the baby bear is seen riding a Yoshi]].
266	** In HTFA GB, during the introductory cutscene, Bowser's thought bubble briefly shows Allay having wings similar to those of [[Franchise/TouhouProject Flandre's]].
267	** The second level of HTFA 4 is called Lemmy's Crazy Fortress. It happens to look like a typical castle-like level. Replace the "Fortress" part with "Castle" and "Lemmy" with either "WesternAnimation/BugsBunny" or "WesternAnimation/WoodyWoodpecker", and you get the idea.
268	** HTFA Maker's splash screen shows Cuddles with Handy's accessories (minus the bandages, natch) holding a gem, with a pose similar to Mario's in ''VideoGame/SuperMarioMaker''. Even the game icon shares the same pose.
269	* SideView
270	* SlippySlideyIceWorld: The icy/snowy levels.
271	* SoundOfNoDamage: Can be heard during battle against Wheel Gator if he's hit normally, as he is only weak against [[KillItWithWater water]] (Toothy's [[MakingASplash Tear Pump]] doesn't work, for some reason).
272	* SpecialAttack: The special powers. Limited in use and its gauge can be replenished by picking up [[ManaPotion special candies]].
273	* SpikesOfDoom
274	* SpreadShot: In HTF Origins, there's a powerup which shoots 3-way balls.
275	** Brandy and Neena's Special Power is this.
276	* SpringsSpringsEverywhere: A few levels in HTFA Land feature many springboards for level navigation.
277	** You can also induce this in HTFA Maker by creating a level with lots of springboards.
278	* TheStinger:
279	** After the credits roll in HTFA 2, a message is shown as a hint to access the hidden level select screen.
280	** In HTFA 5, if you choose to sit through the credits, the message "Happy Tree Friends is not dead" can be seen after the credits end. This is actually a reference to the HTF show's hiatus that occurred between early 2011 (or late 2010 if one uses the "See You Later, Elevator"'s release date) to Christmas 2011, and that hiatus period is infamous for the HTF Break episodes that mostly end with the "Happy Tree Friends is dead!" message, which for the first time may alert the fans, but after several times end up irritating them. HTFA 5 itself was made during the show's hiatus.
281	** HTFA 6 originally didn't have this. However, its most recent update includes this in the form of Franchise/MegaMan showing up after the "Presented by Dunami" message comes up, which marks the end of the credits roll. He's shown holding up a wooden sign with [[{{Engrish}} a rather hilarious Engrish]] message: "Stop lefting HTF fandom!"
282	** After HTFA Land's credits roll ends, the heroes are shown standing together on the grassy ground... while Bowser falls into the water in the distance (followed by the text [[SequelHook "To be continued..."]]). The screen then turns into black and the game says "Good bye and see (you) next time in ''Happy Tree Friends Adventures 7''!". [[spoiler:The game also tells you in that same screen that you can get 30 extra lives by performing the Konami code.]]
283	* SugarBowl: Happy Tree Kingdom, the kingdom the protagonists are living in.
284	** In HTFA Land, there's [[EverythingsBetterWithRainbows Rainbow World]] where the rainbow critters originally reside. [[spoiler:A SugarApocalypse in the form of Bowser's army taking over that world is actually happening when you get there.]]
285	* SuperNotDrowningSkills: The playable characters can swim, yes, but they're not equipped with any kind of diving gear. Normally, in HTF universe, they'd drown easily.
286	* SuperTitle64Advance: ''Happy Tree Friends Adventures '''Game Boy''''', despite not actually being released for UsefulNotes/GameBoy. It's actually a {{Retraux}} game in Game Boy style.
287	* TakenForGranite: Nutty's Special Power allows him to freeze weak enemies into a chocolate block.
288	* [[ThisIsADrill This Is a Carrot Drill]]
289	* TomatoSurprise: In HTFA 6, after you defeat [[spoiler:Tiger General]], [[spoiler:Bowser zaps the dead corpse with a thunder and shows up, flying in his clown car and informing the heroes to get him on his fortress]].
290	* TransformationTrinket: Allay's crown, when worn, can transform her from being an ordinary yellow bear with brown hair and blue outfit to a pink princess bear in red dress (as shown in HTFA 3). Note that this isn't actually part of her character, as it's only made up by Radel himself and Allay herself isn't his fan character to begin with, which can make other people not knowing the real Allay mistake her for Radel's character (this is often shown in fanworks, where the character is often credited to Radel himself).
291	* TrialAndErrorGameplay: A certain vertical section in the second level of Bowser's fortress. Unless you know full well which directions you will take when falling through this section, get ready to die multiple times in this section, as the hazards there deal ''3'' points of damage each (when the player's max is 8).
292	* UndergroundLevel: The levels that take place in, well, underground.
293	* UnderTheSea: The completely underwater levels.
294	* UnexpectedGameplayChange: In HTFA 2, the two levels where you get to ride either [[VideoGame/TwinBee TwinBee or WinBee]] are [[UnexpectedShmupLevel shmup levels]].
295	* UnexplainedRecovery: No matter how many times Bowser ended up dying after almost each game (this is more prevalent in the earlier titles), he'll always come back unharmed and ready to kidnap someone once again. HTFA 5 tried to justify his survival after his defeat in HTFA 4 by having him hitching a ride ''inside a meteorite'', which is just as absurd as it sounds. [[FridgeBrilliance He might be like the Happy Tree Friends, though, as they always come back from every death as well, and how they fully recovered also remains a mystery.]]
296	* TheUnfought: In HTFA 6, Pete the Koopa and the twin raccoons Lifty and Shifty.
297	* {{Unwinnable}}: If a GameBreakingBug is in effect, most of the time. It's even worse on games that lack any save feature (HTFA 1, HTFA GB).
298	** In HTFA Maker, due to the levels being entirely user-generated, this issue can happen either due to the lack of testing or use of wrong character when a player gets to play it. For example, a level that requires a high jumper to progress through the level is literally unplayable with any character but [[InASingleBound Flaky]].
299	* VictoryPose: Used in HTFA Land and HTFA Maker.
300	* VoiceGrunting: Starting from HTFA 4 onwards (except for [[{{Retraux}} HTFA GB]]), every playable character is given short voice clips whenever they jump, getting an extra life or die. Starting from HTFA 6, they also make a noise every time they shoot.
301	* WaddlingHead: The rainbow critters in HTFA Land.
302	* WalkDontSwim: Applied in the games prior to HTFA 5.
303	* AWinnerIsYou: Hilariously, some HTFA games' credits have these Engrish style sentences because of [=Radel999=]'s English grammar.
304	* YourSizeMayVary: One notable example: A Yoshi appears in HTFA 3, 6 and ''Land''. In HTFA 3, he's large enough to hold seven Happy Tree Friends on his back, while in HTFA 6 he's a lot smaller and can only carry one. A somewhat bigger Yoshi (compared to the one in HTFA 6) appears in HTFA Land, and he can carry up to two Happy Tree Friends.
305	** An extreme example: Bowser is about one head taller than the Happy Tree Friends in HTFA 2. Yet in the same game, Ludwig is about twice the height of Bowser! ...Must be the magic.
