Cows In Action is a series of science fiction books written by Steve Cole. The books are about three cows, Pat (Patrick byron shelley vine), Bo (Bonnie red and whit Baron vine) and Professor McMoo (Angus hightail Barnabus McMoo), who are agents of the CIA, and work to fight against the FBI. In the fictional future of the Cows In Action universe, cows and humans live as equals in the nation of Lucky Burger. McMoo, a bovine genius, manages to construct a time machine from discarded farm equipment and its vital parts from a neighbouring scientist's rubbish bin. The series revolves around the three protagonists' adventures using McMoo's device to travel through time, visit historical settings and prevent the alteration of history by the FBI(the fed up bull institution). In every time period, the trio meet an ancestor of the farmer's horrible wife, Bessie Barmer.
The FBI use termoonators and agents to try and alter history and stop humanity from existing so cattle will rule. The CIA is an agency created by a cow called Madame Milk Belly and directed by director of the CIA Yak or his full name Yakob Buttbuster. The head of the FBI is a buffalo named Toro who is captured in another book not from the series.
