Top Definition
A giant freakish-looking plant-monster that is clad in nothing but red and white polkadotted underwear. Attacks by either puking up toxic sludge (in Super Mario Sunshine) or by leaping up and stomping down, and swinging cages which are permanently welded to its arms (in Super Smash Bros. Brawl). Has also been spotted playing golf for some reason.
