Arumajiron (アルマジロン, meaning "Armadillon") are armadillo enemies from Donkey Kong for the Game Boy. They appear in the Desert, making their debut in Stage 5-7. They behave just like Rappies: they walk in circles around the environment, up walls and on the ceiling. They do not hurt Mario, and can only push him. They can be stood on in order to hitch a free ride on their hunched backs, but can not be picked up nor defeated in any way.
