Similar Machine in The South
In The South, general stores sometimes have a similar machine. As I recall, there is some ruse to get you to put your finger in a hole, and when you do a door flips open and a fake raccoon/skunk/groundhog or whatever jumps out at you. It's pretty effective.
I always wondered what these machines are called and how to build one. I work in a hospital, so I was thinking of a "Check your blood pressure" machine complete with dials and other official looking features. Just one of those projects I haven't got around to yet.
