History VideoGame / HappyTreeFriendsAdventures

* LetsPlay: This game is obscure in popularity, but there are few people who played this game and atleast made playthroughs of it.
** xxxGreyFoxNinja11xxx did a LetsPlay of HTFA 4. [[https://www.youtube.com/watch?v=j2TmLVnzNhc Part 1 begins here.]]
** [[https://www.youtube.com/playlist?list=PL5B84BD7455B07ADA blamaxtric did HTFA 6.]]

** Wirgliusz did HTFA GB. ([[https://www.youtube.com/watch?v=JEsGOxF4wZA part 1]], [[https://www.youtube.com/watch?v=xk04LU2fEG0 part 2]]) (also in Polish)

* SelfImposedChallenge: Despite no one attempting this kind of challenge (as of this writing), due to how the game is set up, you can either try:
** OneHundredPercentCompletion: This means that you have to collect all pickups (gems/fruits, power-ups, etc.) and defeat all enemies (that aren't invulnerable, obviously). The series never keeps track of %-completion, so this can fit in such challenge. It's harder than it sounds. For a better challenge, either play [[CheckPointStarvation HTFA 1 or GB]] with this exact restriction or play the other HTFA games with this restriction but you're not allowed to reset (either using passwords or loading saves). HTFA Land might unintentionally reinforce the latter due to a GameBreakingBug regarding game saves.
** MinimalistRun: Collect as few pickups as possible (if possible, ''never'' picking up items ''at all''). The latter tends to be outright impossible in some games due to certain item placements outright blocking the only path to move forward.
*** In HTFA 1, this makes it a "three-heart" run, due to [[EarlyInstallmentWeirdness you always starting with three health points every time you die]].
** NoDamageRun: [[ExactlyWhatItSaysOnTheTin Never take any damage.]]
** SoloCharacterRun: As each character tends to have their own distinct trait that distinguishes them from each other, challenges like [[InASingleBound Flaky-only]] run (her high jump can be useful for {{Speedrun}}s), Petunia-/Giggles-only run (same reason as Flaky, but more emphasis on speed than taking tricky shortcuts), etc. are possible. Some character-only runs tend to be rather dull due to traits that don't make much difference in gameplay (Nutty, Lemy, Allay, Tacho) and certain characters aren't possible to be used in a pure SoloCharacterRun due to being need to be unlocked (Brandy, [[spoiler:Izzy]]).
** Obviously, there's the usual {{Speedrun}} challenge. As mentioned above, Petunia and Giggles are recommended choices for such run.
** For HTFA 6 and later games (except for HTFA GB), the no-"Special Power" run, meaning you can only damage enemies with your regular shots and you can't take advantage of Special Powers for level navigation (Cuddles's [[ThisIsADrill Carrot Drill]], Flaky's [[InASingleBound High Jump]]).
** For ''Origins'' and ''Land'', the "no [[GoombaStomp stomping on enemies]]" run. For the latter game, try doing so while also restricted by the no-"Special Power" challenge mentioned above.
** For games with adjustable number of starting lives, you can set the number to 1, which essentially makes it a No Death Run, only if you also agree to not pick up any extra lives and agree to not have 100 collectibles (only possible in certain games). Combined with "no continuing from passwords/game saves", the challenge becomes FinalDeathMode.

* PlatformHell: Most of these games do have waves of moving platforms along with a deadly pit, be straightly careful when you get to parts like this.

* LuckBasedMission: In HTFA 4, the boss battle against Ludwig is this, as mentioned in the NintendoHard section. His machine fires one bullet per shot, but there's no exact pattern of where the bullet will be shot to. So, you 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.

* NintendoHard: Surprisingly, few bosses and levels may tend to be hard for some players.
** For example, HTFA 4 has Ludwig von Koopa's flying machine serving as the surfing stage boss, with his bullets that are almost unavoidable and it's nearly the hardest for players.

* DummiedOut: A HTFA 6 beta had a test level where Radel999 tests out every playable character's [[SpecialAttack Special Power]]. No such level with the similar design appears in the final game.

* TheDragon: Bowser sometimes has tamed monsters, one of them is a literal Dragon in ''Happy Tree Friends Origins''.

** In HTFA 3, you fight [[TheDragon 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.]]

* BraggingRightsReward: Defeating [[spoiler:Flippy]] in HTFA 2 will [[spoiler:award you 20 extra lives]].

* AuthorTract: 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 fangame depicting Bowser in the place of Bill Rizer, and the name of the game is Bowser the Warrior.

''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 deviantART.

The series involves the main cast of HTF as they have to rescue Giggles (now Allay as of HTFA 2) from Bowser (the main villain of the ''Franchise/SuperMarioBros'' series), and the game is a crossover to many famous video game franchises like Super Mario (the most of it), Mega Man, 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 10 as of 2016), many of them still being made or on hiatus. The list of the series' games are here:
* ''Happy Tree Friends Adventures'' (2009, released)
* ''Happy Tree Friends Adventures 2'' (2010, released)
* ''Happy Tree Friends Adventures 3'' (2010, released)
* ''Happy Tree Friends Adventures 4'' (2010, released)
* ''Happy Tree Friends Origins'' (2010, released): First spin-off centering around Lemy and Allay.
* ''Happy Tree Friends Adventures 5'' (2011, released)
* ''Happy Tree Friends Adventures 6'' (2011, released)
* ''Happy Tree Friends Adventures Game Boy'' (2012, released): Another spin-off and it's ExactlyWhatItSaysOnTheTin, it's a UsefulNotes/GameBoy-styled spin-off. Unlike HTF Origins, the standard six Happy Tree Friends are playable instead of [[OriginalCharacter fan characters]].
* ''Happy Tree Friends Adventures Land'' (2013, released): The third spin-off. Not only you can play as one of the standard six Happy Tree Friends, but you can also play as Neena or Tacho, who are playable for the first time in this game.
* ''Happy Tree Friends Adventures Maker'' (2016, released): Basically ''WebAnimation/HappyTreeFriends'' meets ''VideoGame/SuperMarioMaker''.
* ''Happy Tree Friends Adventures RPG: The Fire Point'' (2016, beta): The first and only RPG spinoff of HTFA. Made using RPG Maker VX Ace.
* ''Happy Tree Friends Adventures World'' (2016, incomplete): Development began in 2014. The sequel to the ''Land'' spin-off. It is revealed that the game will have its screen bigger than the previous one.
* ''Happy Tree Friends Adventures 7: The Greatest Battle Ever'' (20??, incomplete): Development began in 2012. Currently in development hell.
* ''Happy Tree Friends Adventures 3D'' (20??, tentative): First and likely the only 3D game of the series. However, it has almost no information of it, and it is likely confirmed that it is being made in Unity. Only sign of evidence so far is [[http://htfmegaman.deviantart.com/art/HTF-Adventures-3D-Project-302514458 this deviation]] teasing the game.
* ''Happy Tree Friends Adventures 8: The Daemon Conquest'' (20??, tentative): The tentative eighth main installment of the series.

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 (except for HTFA 2, which is still missing) along with his other game projects in [[https://www.mediafire.com/folder/y2m9gyh0w4lmf/Dunami_Projects a MediaFire folder]].

[=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 HTFA 6 and HTFA 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 isn't the only series he made.

** Flaky's [[RollingAttack Special Power]] in HTFA 6 is basically [[SonicTheHedgehog Sonic's Spin Dash]].

* SuperTitle64Advance: ''Happy Tree Friends Adventures '''Game Boy''''', despite not actually being released for GameBoy. It's actually a {{Retraux}} game in Game Boy style.

* ''Franchise/WonderBoy''[[note]]Represented only by a [[PaletteSwap recolored]] character.[[/note]]

* ClimaxBoss: [[spoiler:Tiger General]] in HTFA 6, he's like Cossack from the [[MegaMan Mega Man]] 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]].

** The later games also deal with {{VideoGame/Contra}}, [[MegaMan Mega Man]], [[AdventureIsland Adventure Island]], and some other franchises from the NES and from Konami.

** The games are homage to the classic NES games such as the [[WesternAnimation/TinyToonAdventures Tiny Toon Adventures]] game series, [[AdventureIsland Adventure Island]] and [[MegaMan Mega Man]].

* XMeetsY: For the most part, this series is mainly ''WebAnimation/HappyTreeFriends'' meets ''Franchise/SuperMarioBros''.
** HTFA 3 is the former meets ''VideoGame/AdventureIsland'' series, down to the graphic style (mostly), map, and the character selection screen.
** HTFA 5 is HTF meets ''VideoGame/Kirby64TheCrystalShards'' (despite not in 3D), [[WordOfGod according to Radel999]].
** HTFA 6 is, obviously, HTF meets ''Franchise/MegaMan'' series, as shown by the majority of the graphic and music style used and most of this game's bosses and enemies.
** HTFA Land is basically HTF meets ''VideoGame/NewSuperMarioBros'' series (with a dash of ''VideoGame/MegaManX'', thanks to the bosses featured), considering the similarity of most world themes and the overworld map (even including the castle and airship levels; but the gameplay is progressively linear, you can't revisit finished levels).
** As mentioned before, HTFA Maker is HTF meets ''VideoGame/SuperMarioMaker''.

The series involves the main cast of HTF as they have to rescue Giggles (now Allay as of HTFA 2) from Bowser (the main villain of the [[SuperMarioBros Super Mario Bros.]] series), and the game is a crossover to many famous video game franchises like Super Mario (the most of it), Mega Man, 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 10 as of 2016), many of them still being made or on hiatus. The list of the series' games are here:

* CrossOver: This game mostly cross-overs with [[SuperMarioBros Super Mario Bros.]] due to Bowser being the main villain and is responsible for summoning his minions (including his Koopalings).

*** 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 Super Mario Bros.]] universe. Other non-SMB and non-HTF characters are considered lacking in variety.

** Wirgliusz did HTFA GB. ([[https://www.youtube.com/watch?v=JEsGOxF4wZA part 1]], [[https://www.youtube.com/watch?v=xk04LU2fEG0 part 2]])

The list of the series' games are here:

* LostForever: The HTFA game engine (based on HTFA 6, requires Multimedia Fusion 2) which was packaged with [[VideoGameRemake HTFA Deluxe]] is no longer available on the web. Can be averted if someone managed to ask [=Radel999=] for it and share/re-upload it somewhere... though as of now, this has yet to happen.

* VictoryPose: Used in HTFA Land.

''Happy Tree Friends Adventures'' is a fangame based off the ''WebAnimation/HappyTreeFriends'' series created by a polish Konami fan named [=Radel999=] (or [=HTFMegaman=]) from deviantART.

* {{Backtracking}}: There's one instance in HTF Origins, disguised with AdvancingBossOfDoom. You have to return to the very first starting point in the pyramid to make the boss fall into the lava so you can properly fight him later (you normally can't deal damage to him otherwise).

* ChekhovsGun: There's lava pool inside a pyramid in [[ShiftingSandLand Desert of Koopa]] in HTF Origins. It seems to be out-of-place, considering that you don't see any other lava pools like it in the same level section. Cue {{Backtracking}} in the deepest part of the pyramid after triggering an EscapeSequence from an AdvancingBossOfDoom.

** In the first three HTFA games, Flaky had visible ears, which coincidentally makes it an accidental DevelopmentGag on part of the actual show (one of the early HTF concept arts depicts Flaky (at that time named Corky) with ears)
** Related to those games, pretty much every Happy Tree Friend not named Cuddles (except for [[spoiler:Flippy in HTFA 2 only, where his sprite was taken from ''Flippy Attack'' instead]]) suffer from this because of how awkward the sprite edits look (weirdly enough, neither Giggles nor Petunia use their own sprites from the same game where Cuddles's sprite originated). It was until HTFA 4 the ''Blood Money'' sprites became slightly polished, and by HTFA 5, Radel pretty much ditched those sprites.

* InNameOnly: Starting from HTFA Maker onwards, 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.

* LaterInstallmentWeirdness: HTFA Maker is the first HTFA game published after [=Radel999=]'s confirmation regarding the removal of blood and gore from the series (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.
** Organic enemies now explode in a puff of smoke instead of blood and gore. Even the Happy Tree Friends don't bleed anymore when they get damaged by enemies/hazards.

* 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.

* LudicrousGibs: Each enemy you kill explodes into a gorefest just like seen in Happy Tree Friends' episodes. Averted in the later games starting from HTFA Maker, as confirmed by WordOfGod.
