Welcome to Gnome Gardens . . . where nothing is what it seems . . . Harry and Jamie know that their new home is cursed by an evil gnome. And the gnome has a whole army of nasty creatures he's using to frighten them off. This time, the gnome drags them into a smelly sewer and brings them face to face with a giant rat! Can Jamie, Harry and Milly get out of their pongy prison, or will they come to a sticky end?
