To Decorate Cookies: Using chocolate icing, pipe hair. Using white icing, pipe two small dollops for eyes; press 1 brown milk chocolate candy on each. Using red icing, pipe pea-sized dot for nose; press on 1 red milk chocolate candy. Pipe on ears and mouth. To make hats, cut fruit snacks in half vertically into rectangles. Fold rectangles in half, creating squares. Fold squares in half diagonally to create triangles . To create hat brims, slightly roll up 1 edge of each triangle. If necessary, gently pull and stretch hat to fit cookie. Fold hat tip down, at an angle, to meet brim (see photo). Using white icing, pipe small dot where tip of hat meets brim; press 1 red milk chocolate candy on dot. Let stand until frosting is set. Store in airtight container, using waxed paper between cookie layers.
