- 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 it was originally not meant to be in the FC World (See Unused Content). It is revealed that it was used around version 0.06, where Buyo Buyo appeared in one of the houses at the Barracks Settlement, and gives you the effect.
