Lyle is an anthropomorphic saltwater crocodile, and the main titular protagonist in Lyle, Lyle, Crocodile, as well as the popular the book series by the late Bernard Waber. He may be unable to talk, but he has an incredible singing talent.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
