Ghost Goomba

Ghost Goombas (generically referred to by Nintendo Power as ghosts ) are Boo-like ghosts of Goombas found in Super Mario Land 2: 6 Golden Coins. They are only present in the third level of the Pumpkin Zone. True to its appearance, the Ghost Goomba is invincible like a Boo, but moves and acts like a Goomba. Green Shells and Stars are effective in defeating it.

A Ghost Goomba appears in the concept art of Super Mario Odyssey, suggesting they may have been planned to appear in the game somewhere early in development.

The ghost has no physical form and is totally immune to Mario's attacks. Mario must run through it quickly, as it moves in a very unpredictable manner.''

Trivia

 * In a KC Deluxe mini-guide, Ghost Goombas are referred to as the ghost of Chibibo. In actuality, Ghost Goombas are approximately the size of regular Goombas and even slightly bigger than the game's Boos.
