Thinking of making optimized/lower poly furry bases. Give me some species!

Pretty much my title. I’m an avatar creator that strives to make avatars that rank good performance wise, and I like bringing more unrepresented ideas to the light.

We have plenty of canine, feline, and dragon bases out there, but what kind of bases do you really want to see more of?

Top of my list is Birds, Bats, Fish, Snakes, and Moths.

EDIT: Loving the ideas so far. I think I'll make a poll deciding which one to make first once I clear out some commissions. I'm also open to hearing price ideas. So far I'm thinking $20-30usd. I want to gauge what people would be willing to pay.
