Oh, these are creepier than you might think. I licensed the music for the wolfman toy (second from the top), so I got one for free from the manufacturer. One of its hands fell off in shipping, but I kept it on my desk until it started singing and dancing by itself when I left my office. No motion sensors on it to explain its sudden activation; just random moments. I can't remember how I got rid of it, but I live in fear that it will reappear in my office some day.
