This is probably and always will be, my most epic ref sheet!!!

Dark Chatty, the demon squirrel.

DC does have hair, but its kinda blended into the background. He has a short mohawk. Black and dark grey!

The stripped part on the right, is the top side of his tail and the lighter grey part under it is the bottom of the tail.

Towards the bottom of his arms and legs, his fur becomes a much darker grey.
