Coal

Coal is a dark gray dog-like rock the shape and size of a boulder, with four dark, stubby legs, a similarly rock-like tail and black snowflake marks on her cheeks. She has a bored, tired, somewhat cross expression on her face, having dark circles under her eyes and thick, furrowed brows. She wears a red two-sided satchel over her back with a flag on it, the flag having a similar crossbone design to the marks on her face. Coal is a rather stoic Toon, though she often appears grumpy, frequently growling. She generally isn't excited about many things. (From DW wiki)
