The McNasty twins are horrible. Even fish put their fingers over their eyes when they see the twins coming in their ship, The Rotten Apple! But when the despicable pirates' never-ending quest for treasure takes them to the island of Little Snoring and brings them up against honest youngsters Tat and Hetty, they find they've more than met their match. The Ghastly McNastys and their vile antics will have children squirming and squealing with laughter from beginning to end!
