Dad, Martin and Mia get stranded on an island.
Jumpi causes havoc in the City of Friends when he accidentally presses the overdrive button on Jim the Digger. Totally out of control, Jim runs amok throughout the City. A combined effort by the emergency services and a feat of bravery from Tom means that disaster is avoided just as Jim is about to go over the harbour wall. Jumpi vows he’ll never, ever go near the digger again – ever!
