Attracted to any source of music, Wild Mike is usually in a crate and is released by Otis when he wants to party. He dances wildly which, thanks to Otis' personality, makes him want to join in; however, it is unknown if he really is a mutant (as described by Bessy) or if he is just an unknown animal. He has a strange power that occurs when he dances: Anyone who sees him joins in automatically.
