Ba-Boom is a black baboon with blue cheeks and messy hair. He wears a hat with the Snowmad symbol as well as blue bracelets on his arms and legs. Ba-Boom's brothers look exactly like him except one of them has light-blue cheeks and bracelets while the other has red cheeks and bracelets. Another way to tell the brothers apart is that as they take damage, their fur gets lighter, while the true Ba-Boom's color stays the same. However, no matter which one gets attacked, any of the three could show light blue fur.
