Nummskull appears to be a skeleton Yo-kai. He has a round skull with a pink crack on top. His eyes have black sclera with yellow irises with teal-colored pupils. He has a simple black body with pink stripes around his stomach. Nummskull also has lanky arms with far shorter legs.
Powers and Abilities[]
