Buyo Buyo can be found in FC World B, surrounded by four statues. Interacting with it will give Madotsuki the Buyo Buyo Effect. It reacts normally to the Cat and Knife effects.
Trivia
- When the Stoplight Effect is used, Buyo Buyo's sprite will change and the pupil will disappear.
- "Buyo Buyo" is a Japanese SFX that can mean "flabby" or "squishy/swollen".
- In the game's files, there is an unused Buyo Buyo in the game's regular art style. This could mean he was originally not meant to be in the FC World.
