Goomboss, also known as the Goomba King, is a recurring boss in the Mario series. He is a giant, kinglike Goomba who was first seen in Paper Mario as on of the first bosses Mario and his goomba counterpart, Goombario fight. He later reprises his role as a boss in the games Super Mario 64 DS and Mario Kart DS. He has serious eye problems, as his eyes are always spinning around and around.
Goomboss is an obvious portmanteau of Goomba (the enemy which it resembles) and boss (a videogaming word for a difficult-to-defeat end-of-the-level character). Now, whether Goomba comes from the Sicilian word gumba (pronounced the same as Goomba) is debatable.
