There have never really been any scary pinball machines, but so why not theme a pin around Zelda from Pet Semetary... Complete with choking ball lock? She is one of the creepiest characters in all of cinema. Perhaps she could be part of a Spooky Stephen King creatures montage pin, complete with Creepshow, It, Christine, Carrie, and Shining, Mist.
Not a Pet Semetery pin per se since there wouldn’t be enough in the story, but one more with the Zelda, and Stephen King creatures.
