Professor McMoo, Pat and Bo aren't just any old cows, they're time-travelling, super-clever Cows In Action who visit past and future, around the world to stop the evil Ter-moo-nators changing history . . .
The Time Shed lands on a ship in the Caribbean in 1718, where Professor McMoo, Pat and Bo soon realize that the famous pirates, Blackbeard and Bluebeard are nowhere near as scary as MOO-BEARD, the ter-moo-nator pirate who's captured them - and their ship. They'll need to fight with sword and cow-tlas to escape, but that isn't enough, the CIA still need to figure out what the FBI are up to, and face the real Blackbeard in battle. Bo is seperated from the rest of the gang - can they do it without her? Or will they face a watery grave?
