Chinchillynx

The Chinchillynx is an animal that was mentioned in Dawn of the Croods episode Voice Fail. Ugga mentions one while impersonating Grug who had lost his voice.

It presumably shares features of a chincilla and a lynx.

Trivia

 * The Chinchillynx also resembles the nundu, a kind of magical leopard from Harry Potter, and maybe the possible concept for the franchise in the DreamWorks Animation adaption.
