Melt margarine in large saucepan over low heat. Add marshmallows and stir until completely melted. Remove from heat.
Add Kellogg's® Rice Krispies® cereal. Stir until well coated.
Using 1/2 cup measure coated with cooking spray, portion hot cereal mixture. Shape into balls, inserting wooden stick. Roll and press in coconut or drizzle with chocolate. Faces can be created with frosting, marshmallows or candies, if desired. Best if served the same day.
In a large microwave safe bowl, heat margarine and marshmallows at HIGH 3 minutes, stirring after 2 minutes. Stir until smooth. Follow steps 2 and 3 above. Microwave cooking times may vary.
