Puffy the Dolphin
From the Super Mario Wiki
Puffy the Dolphin is an enemy encountered in Wario: Master of Disguise. They appear in Blowhole Castle during Wario's adventure there. They are anthromorphic, deceased dolphins that wear shades and sport a brown afro and golden necklace. They attack by sending hairballs at Wario from their afro. Wario can only defeat and obtain damage from Puffy the Dolphins if he has activated a spirit switch to its solid form.
A dolphin who loves two things: shrimp and music. Years ago, he left the music scene to live as a recluse inside a scary mansion. And eat shrimp, presumably.
