You can harvest a whole pumpkin patch full of these sweet treats in minutes.
For each pumpkin, cut one circus peanut in half. Cut a small piece from a green gumdrop and trim away the sugar coating so you have a dot of the sticky inside. Use this piece as glue to stick the two halves of the peanut together, bottom to bottom.
Roll the pumpkin in the palms of your hands to make it round. Press lightly; you don't want to compress the candy too much.
Use a skewer or toothpick to poke a hole in the top of the pumpkin and draw lines down the sides. Cut another small piece from the green gumdrop and roll it in granulated sugar, molding it into a slightly conical stem shape with your fingers. Insert the stem into the hole on the top of the pumpkin.
