The Saber-Toothed Squirrel is a wild and dangerous small squirrel-like creature from the Ice Age.
Retro turns a squirrel into a Saber-Toothed Squirrel. It seemed very dangerous when it attacked Stitch, but the liitle Saber-Toothed Squirrel fell into the trash can. It was probably later rescued by Stitch. It has long fangs, long ears, brown fur, a pink tail with fur on the tip of it, and sharp claws.
The creature may be a refrence to the character Scrat from the "Ice Age" film franchise.
