Stoneface is a small brown Ankylosaurus-like experiment with armor plated hide with spikes protruding from head, down around his back, to a spiked club at the tip of his tail. Designed to eat large amounts of rocks and eats more than his body weight. When he gets big enough, he is then programmed to find the nearest hill, roll down it, and smash into the nearest town. Seen in pod form in Stitch! The Movie. His one true place is helping Holio (606) in getting rid of debris.
