Marrio is the father of Mabbio, Weebee, and Mawepieo. He is a plumber like Mario and Luigi. Because of this, they are good friends. Weegee does not like him because he is friends with Luigi. He was born completely bald and has been bald for all of his life. Since he is a plumber, he did not join the Anti The Anti-Weegee Alliance Weegee Foundation.
