A Goomba Mask is an item that appears in Super Mario 3D World.
Goomba Masks sometimes appear after the player has defeated a Goomba. They can be worn on the player's head allowing them to disguise themselves as a Goomba. This also makes the player hardly noticeable.
- Goomba Masks should logically lose their functions if their wear attacks an enemy, but this does not occur.
- A paper-machê variation appears in Paper Mario: The Origami King. When Paper Mario wears it, he pretends to stumble drunkenly. Olivia then laughs at his antics.
