It has a flat, dome-shaped head with two blank and green eyes, orange-tipped stubby flaps resembling Knuckles' dreadlocks, and a thin grey muzzle. Possessing no neck, it has a long body shaped like an arch with thrusters on its back, a wide pelvis, and a thin grey intake across its chest. It also has thick grey and red arms, three-fingered orange hands with solid grey fingers, thick red legs with orange rims, and red and grey feet fashioned in the image of Knuckles' shoes.

Overview
