MELT chocolate in microwave as directed on package. Use a clean small paint brush to paint a monster face on the inside of each of four clear 5-oz. plastic cups with the melted chocolate. Refrigerate until ready to use. (You could also just draw on the outside of the cups with a permanent black marker)
ADD milk and food coloring to dry pudding mix in medium bowl. Beat with wire whisk 2 min. or until well blended. Immediately pour into prepared cups.
