Dungzilla

Sally Tinker - the world's foremost inventor under the age of 12 - is back with a new adventure in invention. When a friend's beloved pet goes on a dung-rolling rampage through her home town, Sally is stuck in the muck - just how much manure can she endure while saving the world?
Sally has built a machine capable of enlarging any object, but when she tries resizing a slice of pizza, she accidentally enlarges a dung beetle to scary proportions. As the hungry beetle rolls itself a dung ball large enough to crush an entire town, Sally races to fix her new machine, but not before her baby brother Joe makes himself enormous and saves the day. Unfortunately, Joe can't be shrunk down immediately, and he desperately needs a nappy change.
