Just when Zombie's life seems to be getting back to normal, it gets turned upside-down again. Adorable little gnomes are appearing on everyone's lawns, but nobody knows where they came from or why they're there. But they seem pretty cute, so Zombie doesn't mind. At the same time, people are mysteriously vanishing into thin air and no-one knows where they've gone. Can Zombie and his friends uncover where the gnomes are from? Will they find out where people are vanishing to? Will they be able to discover what's going on before it's too late?
