Every year, 10-year-old Midge Gardener and her family (including Dizzy the dog) spend their summer holidays at the Flounder Flats Caravan Park. They do the same old things and see the same old neighbours. But not this year! Very strange things are happening at Flounder Flats this year. When Midge organises The Flounder Flats Dog Show and Fair (FFDSF), things suddenly get even stranger! She hasn't counted on the mystery of the Flounder Flats Ghostfish, or Kaycee Elwood and her kidnapped dog, Pom Pom. And then there's Tig and Shirley Turpie from Rat Island. What are they up to?
