Panther: "Hi! My name is Percy, but everybody calls me Perk." Perk Panther? Maybe.
Lynx: ... No, Lynx doesn't work. Lynxes (linges?) are too mellow.
Echo Ermine? Herman Ermine? (Ermines are small, tho, IIRC, like weasel-sized.)
Heh ... instead of Cody Coyote, maybe he's attached to Litho's Magnificent Donkey, making him "Roadie Coyote?"
Sully Serval? Lanny Leopard? Parker Puma?
Considering that this is not supposed to be a long-term addition to the cast, he's turning into a lot of work!
EDIT: Duh! How about "Brody Coyote?" Hmm... *starts sketching*
