A lookalike of Arthur was in the audience at a Grebes game. He was surprised when Muffy cheered when the other team scored.

Physical appearance
This character looks remarkably like Arthur, except he is a white aardvark with red-framed glasses, a light green sweater, and green and white sneakers. He looked like he was wearing a hat.
