Blunder is convinced that he and Thud have to save a princess if they want to become True Heroes. Unfortunately, princesses in distress are in short supply in Village Town, so the two nine-year-old knights journey to Castle Kidnapt to hire one. Upon arrival, they find out that the only princess available for saving is a five-year-old girl with a thirst for adventure. Can Thud and Blunder keep up with Princess Punch, or will they end up being the ones in need of saving?
