Combine margarine and marshmallows in 2-quart glass bowl. Microwave (high), uncovered, 2 1/2-3 minutes or until marshmallows are puffed. Add orange gelatin; mix until combined. Stir in cereal until well coated. Mix in candy corn. Cool enough to handle. With buttered hands, form mixture into 24 balls. Place on waxed paper until cool. Wrap tightly in plastic wrap for storage. Tips: Pieces of cut black licorice can be substituted for candy corn. Mixture can be pressed into greased 13- by 9-inch baking pan and cut into squares for serving.
