The Grunts all at Sea

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.
