A Grunt is a bandit that wears a helmet instead of a mask. Their masks can be knocked off with an egg. They will run frantically. They are found in W4-4: Marching Milde's Fort, W6-1: Scary Skeleton Goonies, and W6-Extra: Castles: Masterpiece Set. Yoshi can eat them.
- They are one of the two Shy Guy species that show their faces. The other ones are Shy Guy Ghosts from Luigi's Mansion.
