It would, in fact, be a total hoot if you could rig up a mechanism that would make one of these animal sporrans lift it's head and open and close its mouth...sure to be a hit with the kiddies!

The fox and racoon skins are reasonably reasonable...some of these are a bit steep. I suppose that you could inquire about skunks and the like.
