Grumple is dark brown with two yellow eyes. Its mouth is black inside and appears to have a single tooth protruding upwards from its lower "lip." It appears to be angry.
Grumples only appears in two games.
Kirby's Dream Land
Grumples shares its moveset with Kabu, but moves more quickly. Grumples appears in extra mode.
Kirby Super Star Ultra
Grumples has the same behavior he did in Kirby's Dream Land and only appears in Revenge of the King, which itself is a more difficult version of Spring Breeze, which is a remake of Kirby's Dream Land.
