He is an older "version" of Chowder. He only appeared in "Hey Hey It's Knishmas!". He's has a blue mustashe and taller than Chowder. When Mung was worried about telling Chowder about the Smingerbread House. Truffles said that he's a full grown man... Cat.. Rabbit.. Bear.. kind of thing. Mung looks at the older Chowder and real him was really behind the older him. He's the 3rd Cat/Bunny/Bear and the 1st lookalike shown.
