I think the fact that you brought THREE threads on dummies back might get Ryan's attention
Indeed it did. And it also helped point out that we had multiple threads on the same topic that could be merged together.
Seems there's some ongoing interest in the ventriloquist dummy. A somewhat unorthodox idea compared to the typical witches, bats and ghosts. But then again, so are patterns like my Tooth Fairy or Chupacabra.
These dummies are no doubt creepy, with their small stature, hinged jaw and bug-eyed blank stare. Especially when they start to move on their own.
From your suggestions there are several notable dolls from genre TV shows, movies and books. But I'm picturing this as a "Unique Creation."
