White Castle glow monster premiums

At around 4" tall these aren't really "mini figures," but like the Wendy's Weird Writers I thought they were worthy of a post anyway. They are three Universal monster figures--The Mummy, Wolfman and Frankenstein's Monster--that were offered as prizes in kid's meals at Wendy's fast food restaurants in 1992. Aside from a touch of paint on their faces they're monochromatic, and are made of a firm-yet-flexible soft plastic. They are actually hollow inside and each can be pulled apart a the waist into two pieces, so I'm not sure if the intention was to be able to mix-and-match monsters or what. I've always liked these guys and remember using them as Halloween decorations around the house as a kid. Unfortunately these are the only three monsters in the set (I always thought a blue glow Dracula would have been a natural fourth).
