He drives a magical steamroller that has the ability to access the inside of anybody's dreams. Thanks to this steamroller, he and Retzorg almost always have together-dreams, whether Retzorg likes it or not.

He is capable of crying.
He wants to be a freak but automatically can't because he hasn't appeared in any Marioshames. He would definitely be a freak if he appeared in said shames, though.
