Tripet is a happy little three-legged monster that wants to play! He’s adorable and huggable and stands all on his own. Tripet brings joy and love wherever he goes. Use some Poly Pellets in his feet to help him stand, and then fill the rest of him with Poly Fil. You can even add more legs or arms, as they are all attached separately. Tripet is made in several pieces and then joined together. He’d be amazing in lots of other color combos as well, making him a great stash buster.
