Testing fruits and writing down bugs in the order they appear in creative.
Fruits that didn't have anything aren't included.
Allosaurus: Mink cosmetics don't appear in hybrid form, it is like this for every hybrid form, but since this one still has most of the human body, I assume this might be a bug/unintended.
Rhino: The passive for dashing into and damaging things doesn't seem to work.
Axolotl: My axolotl isn't a funny color!!! (This one has no bugs from what I can tell)
Brachio: Missing the grab move will put it on cooldown, but other moves like suplex won't, idk if this is intended for balancing or if it is simply a bug. Also, when in walk point, you can't hit things like pigs because the range is so bad.
Turtle: Hybrid form removes mink cosmetics, but I know for sure this time they should still be there, given a mink has this fruit in the series.
Hito: No ability category that says "Enlightenment: You have gained enlightenment."
Mole: It just doesn't have a walk point? Wtf Wynd, lazy?!?!
Bison: Much like Rhino, the dash damage passive does not work.
Buddha: Much like brachio, you become too tall to hit anything. Also, when you are in your inventory, because of the beams of light you emit you cannot see your items.
Mega: Somewhat of a smilar problem to brachio and buddha, but it's not as bad due to the player model being much skinnier than that of those zoans. Also no mink cosmetics.
Karu: Touching things like fire/cactus makes you gain karma at an INCREDIBLE rate, near instantly, as well as there being no mink cosmetics.
Jiki: When using Punk Gibson, Damned Punk, and Punk Corna Dio mink cosmetics are not visible as well as the player skin being broken if using a slim skin. Also, Punk Gibson does not increase the players M1 range despite being a giant metal arm.
Oto: All the moves share the same cooldown. I do not know if this is for balancing sake or unintended.
Bara: Most importantly, you can still be hurt by cactus despite being "immune" to slashing/piercing attacks! Also, the legs that are spawned during Bara Split can still be hurt by slashing attacks, which is a major debuff and needs to be fixed this instant! No mink cosmetics appear and slim skins are broken on all moves including Buggy Car and even Bara Bara Festival. No passive appears in the menu telling the player of slash immunity.
Sube: When using Sube Sube Spur, you will not be able to speed up if running diagonally. I have no reason why this might be happening???
Hana: Summoned hands don't work correctly when using slim skins, which is especially noticable when using Cien Fleur. In previous versions, you would stick your hand out forwards when using Veinte Fleur, but now you just cross your arms as the summoned arms float in front of you.
Mini: Mink cosmetics do not appear.
Kuku: Gastromorph changes chests into sponge cake too.
Nagi: Advancement sounds still play, as well as button sounds in the menu.
Doa: Trying to use Door Door on a block that is not as high as your feet simply activates the cooldown without using the ability.
Yomi: The physical body left behind while using Yomi no Reiki has pretty fat arms for a skeleton. The players skeleton model stands still and faces north at the end of Katsuriuta: Fubuki Giri, but only if you hit an enemy.
Horu: Ganmen Seicho Hormone doesn't keep the second layer of the players skin or their mink cosmetics.
Bari: Barrierbility Stairs has no cooldown.
Supa: Spiral Hollow looks really cool for no reason. Also Atomic Spurt has the same problem as Sube's "Sube Sube Spur".
Horo: While using Yutai Ridatsu the player's spirit keeps their mink cosmetics, but the body left behind doesn't, and once again slim skins don't work.
Ito: The user gets hurt by their own birdcage. Black Knight doesn't keep mink cosmetics, nor does it work with slim skins. Attempting to change Black Knight into defensive mode has given me many different issues, such as spawning a permanent unremovable Black Knight (more can be summoned) or straight up just crashing the game.
Zushi: Gravi Zone doesn't keep enemies still or repel them as well as it used to. I don't know if this was a balance change or a bug, but I'm putting it here because it's so dogshit that it might as well be considered a bug.
Doku: The abilities in the menu do not inform the player that they are upgraded when using Venom Demon, nor do they change to reflect this once actually transformed. (Other fruits, such as Gomu or Doru do this.)
Doru: Clones created by Doru Doru no Yakata don't have mink cosmetics, and slim skins don't work. When using Candle Champion, the players skin does not keep its mink cosmetics, nor does it keep the second layer. Candle Champion also cannot hold items correctly, and it has the same range issue as previous fruits. An infinite number of pickaxes can be created using Doru Doru Arts: Pickaxe, though the same cannot be said for creating swords using Doru Doru Arts: Ken.
Kage: By shift using Doppelman, you can summon one in defensive mode, and cannot switch it back to aggressive. You can summon infinite Doppelmen by shift using Doppelman instead of using it regular to turn the ability off. You cannot switch places with any of the cloned Doppelmen, only the "original/current" Doppelman. The cloned Doppelmen can be given shadows to grow in size and become stronger, though this is a bit finicky. When using Shadow's Asgard, the players camera stays at the same height, despite the model growing, mink cosmetics are also lost.
Gura: No bugs, just wanna say I like gura I think it is my favourite fruit, simple but pretty strong :]
Bomu: Also no bugs, but I've just gotta say Wynd, the fact Bomu (funny this one comes right after gura) does the same damage as gura with most moves, and MORE with one of them is fucking insane. Nerf this AND buff gura.
Suke: Maybe it only works on crew members (I'm testing in singleplayer) but Suke Punch doesn't seem to work.
Gomu: Gear Fourth doesn't keep the players mink cosmetics.
Bane: While the mink cosmetics do stay this time, slim skins still don't work.
Gasu: Surprisingly Shinokuni doesn't have a range issue, however; it does still strip away the second layer of the players skin.
That is all the bugs I found while testing out every single fruit in singleplayer. I know it's mostly visual bugs, but I think that's pretty important. Also, from testing all the fruits, I can say this: Gura needs to be buffed CONSIDERABLY, even if just a numbers buff I think it would be good (I think it's fun how it is rn). Also, certain fruits like suna are very very fun. Good job.
