I would really love a Sphynx cat! It has been suggested by plenty <3
A chameleon with its eyes facing two different directions. I mean, that's something really cool about them, why not put it to use? It would also be really cool if there was a background/something in the background on one of them and it was made to blend in.
More Albino animals, maybe?
A deer with its antlers turning into a tree/with flowers as well/just more decoration on the antlers
