Everyone in Harry Hammer's class at school is talking about a fin-tastic new ride that's premiering at Dregoland, Shark Point's amazing amusement park. It's the most terrifying, dorsal-defying, scare-fest in the whole wide ocean! And guess what? Whoever loses the most shark teeth in Harry's class will get to go on the ride before anyone else--and meet Gregor the Gnasher, superstar wrestler.

Harry and his arch-nemesis Rick Reef are tied for first place, but will Harry pull it off and win the contest?
