Turning our everyday rubbish into treasure, the tiny Tindims dive deep for an underwater adventure. The Tindims all have diaries, but nothing exciting to write in them. Until the day that Pinch digs a very deep hole and finds something interesting. Adventure is in the air! The Tindims come face to face with a fearsome Garbage Gobbler, they bump into Stumbling Stone Island and find Skywhistle, Googletop, Eggnot, Peggnot and Cloud. And Broom meets Brush in a story with the happiest of happy endings.
