Made from sweet candies, these scurrying spiders will have partygoers squeal with delight -- not fright. Melt candy coating or candy discs and place in a resealable plastic bag; snip off a small corner. Pipe spider legs onto a waxed paper-lined baking sheet and sprinkle with nonpareils (if desired). Chill legs in the refrigerator until firm. Squeeze small circles of melted coating onto another waxed paper-lined baking sheet and insert eight, chilled legs into each circle. Add a 1-inch candy truffle on top of each circle for the spider body. Add small candies or frosting for eyes; chill in refrigerator until firm.
