Anthropomorphic space animal characters like Fox kind of get an anatomical pass when they're just human-shaped bodies with an animal head and tail stapled on either end, but once you try to deconstruct that idea a little further the shambling homunculus starts to fall apart.

I have no idea if Fox is maybe just a normal-proportioned human dude with way too much hair or instead a weird dog that has crushed its horrible body into the vague shape of a man. Someone needs to ask Nintendo these tough and important questions??
