I've never seen this game before. It's great. I, too, love the Pop-O-Matic - we have the Star Wars version of Trouble, which has a little R2-D2 under the dome with the die!
Did you get a picture of the back of the box? Does it have anything other than the text?
It certainly can't beat the front, with Count Martin Landau, Lazy-Eye Werewolf, O-Face Frankenstein, and Eye-Rolling "Whatever" Mummy!
