Review on Enhance Your Birthday Party with Qrooper Electronic Interactive Function Birthday by Reggie Kern

Okay, it's a lot of fun for about 15 minutes, but if two little kids leave it on in the playroom and talk all the time, it'll turn off and rock up and down. After you turn it off for a while, the demon will be banished and revert to its usual annoying state. It was a little smaller than I expected and the packaging is entirely in Korean (I think) but it was easy to tell where and how to get the batteries.
