Spunky makes friends with a talking snowman, and takes him into a house, where Spunky believes the air conditioning will preserve the snowman all year. They frighten off some burglars. But the snowman decides it's his job to stay outside and make people smile.
Spunky is trying to charge people for haunting houses, e.g. to scare mice away, but he's not scary looking enough. Zoog, a Martian, abducts him to Mars to frighten away annoying visitors from Saturn. At end, Zoog joins him on Earth to help with the haunting business, since Zoog is ugly enough to look scary.
