Could a seemingly easy mission to look after a scientist and his bloodsucking leeches be Max s most dangerous mission yet? Members of an elite group of scientists are disappearing and Chief Harrison’s close friend, Alfonzo Martina, is next. Max and Linden eagerly accept their mission to guard the world-famous professor - until Max finds out that Alfonzo’s specialty is leeches. Not a fan of animals, especially small, slimy, bloodsucking ones, Max soon uncovers a wretched plan to ruin not only the professor but the entire world. Will Flea-Powered Trainers and Sherbet Liquefier be enough to save the two spies, the professor and his leeches from a slimy end?
