Hitboxes are the underlying data that control when a character is hit/grabbed/invincible, etc. in almost all fighting games. Below are the hitboxes for Fishbunjin in gif form so they're easy to view, share and reference. All gifs are about 15% speed. The gifs start the frame before the attack begins, and end a frame after the attack ends.

• Yellow: Hurtbox. When a red hitbox comes into contact with a yellow hurtbox, you or your opponent(s) receive damage. Hurtboxes are always active unless the character is in another "state such as the ones above, even when a attack's hitbox is active.
  
• Red: Hitbox. Vice versa. Most hitboxes only appear for a few frames compared to hurtboxes, called "active" frames. Hurtboxes are still active, and an attacking character can still be attacked even through the hitbox.
  
• Blue: Invincibility. Dodging, teching, ledge climbing, etc. They replace hurtboxes and are active from frame 1, but not near the last few frames, leaving characters vulnerable for a moment. Shields are colored the same thing.
  
• Purple: Grab. Ignores shields and activates an animation and grabbed state if it comes in contact with a hurtbox. All characters have a grab.
  
• Green: Super Armor. Does not flinch when attacked, but still takes damage.

Fish can extend his down strong by inputting down strong again for each slam backwards.

Hitboxes differ slightly for the dumbbell if charged or uncharged.

See the end of this guide for charged down special hitboxes.

Down special has 8 different stages Fish can charge through. Each stage extends its hitbox further but takes progressively longer to reach. Stage 7 and 8 have super armor.

Stage 2


Stage 3


Stage 4 (Stars)


Stage 5 (Fire)


Stage 6


Stage 7


Stage 8 (PLANET DESTRUCTION FORM)

All gifs were collected by me. No credit is needed, but appreciated.

All gifs can be sped up without any file size issues. A website like this one https://ezgif.com/speed/ can speed up the gif fine so you can view it at 100% speed. (300% is close to in-game.)

I plan on including frame data for each attack once the frame data collection is complete -- for now I'm just offering the gifs for every attack.
