The sixth in this hilarious series based on the character of Harry Hammer, a young hammerhead shark making a big splash on Shark Point. It's exam time in Shark Point, and Harry's mum has laid down the law: if he doesn't work hard at revision then he can't go to the school party at the end of term. And Harry has to go to the party - they're holding a dance competition and first prize is a Fintendo DS! But Harry hasn't counted on the efforts of number one enemy Rick Reef. Can Harry beat the competition and win the award?
