"Curly's visiting his Grandma Rose by the ocean. His friend Pook, the mischievous Fent, has come along too. They soon discover that Mr Smythe, the man offering to buy Grandma's house, will do anything - ANYTHING - to get it, so that he can build a new marina. Even if it means tearing up Grandma Rose's garden, recording secret meetings with the mayor, destroying the local beach and sending a shark after Curly and Pook. That's not all. It turns out that Fents have cousins ... the Grents. And if Pook the Fent is scared of Grents, they must be trouble! Soon everyone turns up at Grandma's house: Curly's family, Pook, the Grent, Mr Smythe, the mayor, the police ... and a band of angry, environmentally aware pensioners dressed up as sea creatures. In all the confusion, can Curly produce the evidence that will save Grandma's house?"--Provided by publisher.
