Bonzo is easily distinguishable due to his bulky body shape, composed of his round torso and relatively short limbs. His head seems to connect with the torso without a visible neck.
He has gray fur, lighter on the mouth and darker on the torso; supplemented by black stripes on his head and back in seasons 2 and 5.
Bonzo has appeared in two different outfits:
- a blue swimsuit, with red outlines in Beach Blanket Bonzo.
- a cowboy outfit in The Life and Times of the Lasagna Kid, composed of blue jeans with a brown belt, a sand yellow vest, with a black bandanna worn around his neck, and a dark brown Plainsman hat, with flat top.
In short, Bonzo can be described as feline equivalent of Bluto from Popeye cartoons - he is bulky, violent and openly aggressive. In The Life and Times of the Lasagna Kid, it's also revealed that he lacks patience in waiting for ordered meals.
