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 looks for his bucket and the Pig Twins help him find it by the sandpit. Immediately they spot some sandy footprints leading up to the water tap... and some watery footprints leading to a mud puddle... and then some muddy footprints. What can be making all these different trails?
