I had an idea for a Nightmare Before Christmas sequel RP where Jack Skellington and his wife (sorry I forgot her name, but she's the one that's a sort of frankenstein monster thing.) help Santa stop Krampus from taking over both Halloween and Christmas. The idea seemed interesting as the villainn would this time be a Christmas mythos villain (Kampus) as well as would be a scary enough fellow that he might fit in in Halloween Town.
