The World's Cows consist of all dairy cows that live in the world of SPY Fox. They assist Amalgamated Moo Juice INC. with creating dairy milk for distribution.
SPY Fox in "Dry Cereal"[]
Prior to the game's start, William the Kid had already kidnapped all the dairy cows in the world and imprisoned them in N.O.G. William planned on flooding the U.S.A. capital with "none-too fresh" dairy milk via the Milky Weapon of Destruction and frame the cows for the heinous crime, preventing dairy milk from being used again and allowing N.O.G. to take over the dairy world with their goat by products.
After SPY Fox disarms the Milky Weapon of Destruction, William the Kid contacts SPY Fox and tells him even though the weapon is disarmed, he won't save the cows. To prove this, William activates a lever that floods the cow stables, intending to drown the cows in it. Before William leaves, the door to the secret passageway to the cow stables slams shut on William's ascot, forcing him to abandon it and giving SPY Fox a clue on where the door is.
After SPY Fox finds the passageway and gets past the obstacle(s) blocking the way (either alligators in the Alligator storyline or Hong Kong Doodle in the Cock-a-Doodle Fu storyline), he stops the milk flooding the stables and frees the cow by pulling up the lever William earlier used.
It is presumed that the cows returned to work at Almagamated Moo Juice INC after the milk crisis was resolved.
