C. Round resembles a red uncrowned checker piece with brown legs protruding from its edge and a smiling dog-like face on one of his flat sides. He has no arms. When turning into K. Round, he appears as a bigger checker piece with a crown and tall muscular legs. C. Round does not know how to speak English, but he tries to, and he's almost always excited and likes to dance. If you bow to him, he'll bow back.
