1. Line a baking sheet with parchment paper. Arrange 10 donut holes on parchment, leaving 2 or 3 inches of space between them. Insert one or two horn-shaped candies (such as Hot Tamales, Mike & Ike, Good and Plenty, or candy corn) into each donut hole.
2. Melt 1 cup of green candy coating according to the package directions. Working on one donut hole at a time, remove the candy pieces and spoon the melted candy coating on the donut hole, letting the excess drip down the sides. Return the candy to its place. Decorate with candy eyes and orange sprinkles. Let stand until set. Makes 10 servings.
