Chihuahua back legs, and whole body and head. Chihuahua back legs are pretty dang strong they can jump over two and a half times their height with those little legs. Of course they have chi heads and their ever so cute ears. So really the only squirrel parts are the tail the teeth and the front hands because squirrels are so good at using their hands.

No they definitely do not land softly, the ones that get spaced well they eventually blow up in space or become bloody balls of fire. Even those that are only lifted 10 feet in the air and then set free, fall with a little extra force than normal, thus some broken legs or ankles to remember their transgression by.
