On the night before Christmas, something is flying over Hamlet, Vermont, but it isn't a sleigh with reindeer. It's a UFO bearing five aliens on a mission: to free this planet from its evil dictator, a fat man in a red suit and a long white beard. Disguised as Earthlings--well, elves--they meet Mayor Grass, fresh from his annual appearance in Santa Claus costume, and capture him. It's up to Miss Earth's students, the Tattletales (all the girls except Pearl) and the Copycats (all the boys), to set aside their differences and concoct a rescue scheme. In this Yuletide sequel to Seven Spiders Spinning and Six Haunted Hairdos, visitors from the Planet Fixipuddle join the familiar folks of Hamlet--Miss Earth, Grandma Earth, and the rival Tattletales and Copycats--in a comic extravaganza that is literally out of this world.
