Halloween Forever. Throwing an epic Halloween celebration would be impossible without the Pumpkin King! He's the leader of his spooky city, and the ghoul that everyone looks to for inspiration. Even when he tries his hand at being Sandy Claws, it's clear where his real strengths lie. This officially licensed Funko POP! Keychain: Nightmare Before Christmas - Black Light Jack Vinyl Figure is scary fun! The one-and-a-half-inch vinyl figure is designed to look like Jack with an oversized head, wearing a striped suit. It's attached to a silver-tone keyring.
