Oh dear. The Grunts are back.

Mr Grunt has to get a POGI (that’s a Person of Great Importance, apparently) to a certain person at a certain time. On an island. And there are others out there who want the POGI for themselves.

Add to this the wheelchair-whizzing Speedy McGinty, the mysterious Max and Martha (sharing a single moustache between them) and Rodders Lasenby who’s turned rudeness into a fine art, and you’ll see why the Grunts’ stolen son Sunny doesn’t know who to trust … or whether Fingers the elephant will sink the boat and leave them all at sea.
