This is an interactive toy. I have set up the mechanisms for the puppet machine, and when the handle of the music box on the right is turned, the bats on both sides and the music box move together, producing sound and moving up and down. It's a lot of fun,I'm experimenting with the combination of the puppet machine and the model; I love them both. This is just the beginning.
