A Goomba Mask is an item appearing Super Mario 3D World. The mask can be found after defeating a certain Goomba. Like several objects in the game, the Goomba Mask can be worn over the player's body. Upon wearing it, enemies will not recognize the player as a threat and will not chase them. But the player can not throw items or get other block items unless it is removed. The Goomba Mask can still be affected by other enemies, however.
- The Goomba Mask make a sound whenever the player jumps. The sound sounds like the sound Goombas make when they see a threat.
