Press popcorn treat mixture in bottom cavities only of pumpkin pan to 1 1/2 in. deep; reserve some unmolded popcorn. Let set; unmold.
Attach 2 popcorn ball halves together on one edge, using unmolded popcorn to prop opposite edge open. Using melted candy, attach Candy Eyeballs and sprinkles and candy corn teeth, and Jumbo Confetti nose. Attach candy strings for hair.
