Bubba

Bubbas are big fish with shades that will eat you if you get anywhere near him. They look and act a lot like Boss Bass from Super Mario Bros. 3. They appear in Tiny Huge Island in Super Mario 64. Bubba appears to be a species of Blurp. Related to them is the small Bub fish.

Additionally, stepping on a Happening Space on Yoshi's Tropical Island would make Bubba switch Toad's and Bowser's position. This is, of course, only in the original Mario Party.
