Welcome to the wonderful world of the Smarties Gold Award winners, Chimp and Zee, the cheekiest, most mischievous, most loveable twins in the whole of Jungletown. Chimp and Zee have eaten all of Mumkey’s bananas, so she takes them to Jungletown to get some more. But Chimp and Zee think shopping is boring and start to monkey about. They play hide and seek with Mumkey, and hide in her banana basket on top of a big grey stone. But the grey stone starts to rumble, wobble and shake, and gets up and walks away! How will they ever get home?
