Dark Dark Boo

Dark Dark Boos (not to be confused with Dark Boos) are shadow versions of Boos. They made their debut in Super Paper Mario, only appearing in Flopside's Pit of 100 Trials. They are the strongest of the Boos in that game.

It can be tough fighting Dark Dark Boos. The player may have a hard time telling which way it is facing. Also, it might blend in with the black block platforms in the pit.
