Onbu moves at a normal pace, only turning upon collision with a wall or bomb. Periodically it will trip and fall down. It then struggles to get back up for a while before returning to its regular movement pattern. It will harm the player on collision.
Upon defeat, Onbu becomes a biological Egg.
When riding Onbu, the player moves at an incredibly slow pace.
"Onbu" is a Japanese word that means "to carry on one's back".
