Hey there, this is a shot in the dark and I'll be amazed if anyone finds it. I'm trying to find an old puzzle I had as a kid, (this was maybe 1999?) that was too hard for me to solve. It was of the gang running from scooby (they're running towards us) who is holding a sheet over his head like a ghost. Behind him is a giant green smoke monster. Most of the puzzle was dark purple, with a vibrant green monster. All of the characters were quite detailed. I'm nearly certain we got this at the warner brothers store at the mall.

Thanks you!
