Gooper Blooper (Japanese: ボスゲッソーBoss Gessō) is a giant Blooper with large and longer tentacles. He is also an ally of Bowser, King of the Koopas. He first appears as a boss in Super Mario Sunshine, where he appears in the levels Ricco Harbor and Noki Bay. He uses his tentacles to smack Mario, draining the plumber's health points. He also sprays goop for Mario to clean. After his debut in Super Mario Sunshine, Gooper Blooper also appears in sports games and spin-offs. Like Petey Piranha, it is quite likely that he is the ruler of his kind, as suggested by his Japanese name, Boss Gessō, "Gessō" being the Japanese name for Bloopers.
