Magrolo Mouse is an anthropomorphic mouse with black fur all over his body, including his tail. He wears red overalls with white buttons and red shoes. His appearence is often compared to Super Mario often, and he grew a hatred towards Mario and anything/anyone that looks like him. He's very twitchy, but doesn't have rabies. He looks kinda crazy, but he's just twitchy. He's usually good-natured and calm, but is easy to lose his patience.
