Melt your candy disks, only microwave 30 seconds at a time or they will seize up into a chunky mess. Stir every 30 seconds until they are fully melted.
Spread the melted disks out on the tray and make sure all of the pieces are covered. Use a spatula to help. Top with a few extra candy corn and Halloween sprinkles. Wait for it to dry. Some people put it in the fridge to speed it up, but since I was going to package it, I was worried about it "sweating" if it was cold.
