1. Start with packaged (or homemade) Rice Krispies Treats, and push each one onto a wooden skewer; set aside.
2. Melt 1 cup white-chocolate chips and 1 Tbs shortening; stir in green or neon-green food coloring.
3. Spoon melted chocolate over all sides of the treats; place on wax-paper-lined cookie sheet.
4. Use M&M's to create eyes and ears, a piece of gummy worm for the mouth and Jujubes for the neck bolts. Refrigerate until the chocolate has hardened, then remove from skewers. Draw on hair and dot eyes with black decorating icing.
