It will be a new creature.
Actually, I've made a design for Squeek. He's sort of a Chippunk, but he has these huge ears that he can use to create a whoosh of air that starts him hopping along the ground really fast. The ears are made of cartiladge that can harden or soften at any time, so they're a useful sheild, weapon, and glider. Plus he has a tail filled with same cartiladge. So it can be used a hand, weapon, or any other tool. I though it was a cool design.
I'd post pictures, but I hid them all somewhere because they sucked.
