Goomboss, also known as King Goomba or the Goomba King, is a recurring boss in the Mario series. He is a giant, king-like 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 video-gaming 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.
- Goomboss does not physically appear in Paper Mario: The Thousand-Year Door, but he is mentioned in the Super Luigi books. However, the English translation referred to the character as the "Chestnut King".
- Goomboss is one of the few Paper Mario exclusive characters to make an appearance in a main series Mario game.
