This mini hardback edition of this Christmas bestseller is the perfect stocking-filler. On Christmas Eve every child leaves out a drink and a snack for Father Christmas. Before long he really, really needs a wee, but what can he do about it? There's a long time to wait before he can get home and when he finally does he's lost his house key! This is a hilarious take on a dilemma that every toddler will identify with.
