How to:
Snack-o-Lantern Fruit Cups
adapted from Disney Family Fun, via Pennies on a Platter
Slice the top off of each orange. Discard it or save it for serving with the cups. Use a sharp knife to cut a cone out of the orange, then use a spoon and/or your fingers to scrape out the remaining orange segments. Rinse the outside of each orange under cold water, then set upside down on a clean kitchen towel.
Cut out the eyes, nose, and mouth as you like.
Cover and refrigerate until ready to use. Fill with desired fruit up to 2-3 hours before serving.
