The Scary Monster Clean-Up Gang

The sly old swamp-witch, Gwrach y Rhibyn, meddles with a powerful new spell in the hopes it will make her Queen of the Wood. But it goes disastrously wrong. The whole town of Nant-y-Ceirw is trapped in the thrall of the hideous Shadow of Don't Care and the Bwganod of the Wood are in terrible danger. It's up to their human friends—Gramps and David and Eleri and Eleri's Nan—to rescue them. Somehow they must defeat the Shadow, but is it possible to fight magic?
