Orson Cart and the Shipwreck Sharks
by Steve Donald
The Prof's up to his old tricks again! He takes Orson and Spud via a submarine to his new underwater lab, where he's learning dolphin language.
However, the prof wasn't expecting the shipwreck of the Toxanic in the same bay, nor the invasion of sharks!
Can Orson save the day, or will they be all at sea?
