Without doubt this is one of the coolest toys I've seen in a long time. He is considered by some experts as a Class Five Full-Roaming Vapor, a.k.a. Slimer from the hilarious movie Ghostbusters, this "Dancing Slimer" grooves to the Ghostbusters theme, wiggling his green rubbery body while waving his lumpy arms. He's approximately 10" tall and about 14" across and equipped with an on/off button. Batteries included.
