Wormwould

Wormwould is an earthworm boss found in Wario Land 3. It's located in The Grasslands guarding the Grey Treasure.

His main attack is to spit rocks to hit Wario. If Wario is hit, he will roll out of the arena and have to restart again. To defeat it, Wario has to use his Ground Pound on Wormwould's head. When hit three times, it will fall, and some vines will grow to allow Wario to get the first music box.
