Scratch Kitten has just got used to life as a Pirate's Cat when he is forced to find a new ship. However, this is not a problem for a brave ship's cat, and when Scratch jumps aboard a fishing boat called the Great Sardine, he thinks he's on to a winner. But where are all the sailors, and the fishing nets, and the FISH? And who are the two annoying young humans that keep on calling Scratch 'Miss Fluffy'? Scratch wonders if he will make it to the end of his journey without becoming a children's toy, but will anyone on board make it to the end of the journey if they don't all watch out for the Ragged Reef?
