Ok, if you've ever walked by a toy store you've probably seen the little creatures attached to the battery operated ball that rolls around in a basket. Well me and a buddy invested into one of those and spent a couple dollars worth of quarters in one of those crane games and got a little white stuffed lion. It was the size of a rabbit. I took my knife and made a cut on the stuffed toy's belly and removed the cotton from the body (not the head) then we turned on the ball and placed it in the cavity and safety pinned it closed. We took a couple of brown markers and painted it leaving a white tail (of course) and wouldn't you know it the animal shakes back and forth with little to no sound from the battery operated ball. The coyotes love it and there's no strings attached. I've even gotten a nice bobcat from it. Good luck with the project.
