Preschool animation based on the popular children's books, introducing children to simple ideas through intelligent, yet basic text and questions. Featuring Wibbly Pig and his favourite toys, Pigley, Flop and Dimple. Wibbly loves looking at clouds but what do they actually do? Soon a cloud takes Wibbly on a journey to find out what clouds really do, and they even pick up a few friends along the way. Watch out for those storm clouds out at sea, they look fierce - dark and thunderous and flashing with lightning.
