Comment Bubble Bug#
If Pyoro or Pyoro 2 catches a Flashing Bean and gets hit by a bean at the same time while a comment bubble appears, the comment bubble won't disappear and descend downwards to this position seen in the screenshot above. It'll stay like that until the comment bubble disappears or quitting out the game.
Interestingly, the comment bubble appears to be layered outside the frame instead of being layered inside.
