Mega Grindarr is a humongous variant of Grindarr; as such, it is a rectangular stone block attached to a long, silver chain. It has no hands, but instead has feet with three digits on each. It has a pair of vigilant eyes, a nose, a large oblong mouth, and an enormous tongue. The enemy is a metallic gray color. In Kirby and the Rainbow Curse, Mega Grindarr is a square shape and is a lighter shade of gray. It no longer connects to a chain.
