Wally Darling has a messy dark blue hair which is styled into a pompadour, has dark red eyes, he has paw pads on his strikingly human looking hands, he's mostly human aside from his yellow skin, he does not have a tail or any form of animal ears, he's mostly human looking. He wears a large white coat that is covered in colour splotches and some of the colour leaks onto his skin which he doesn't bother to clean. Wally has a Coffee addiction and barely sleeps, which is why he has little patience.
