What has two eyes, mouth, and wrinkly green skin? Mark's shrunken head. lt's a present from his Aunt Benna. A gift from the jungle island of Baladora. 
Mark can't wait to show the kids at school his shrunken head. It's so ugly. So gross. So awesome. 
But late one night the head starts to glow. Because it's no ordinary head. lt gives Mark a strange power. A magical power. A dangerous power. . . .
