The player controls a UFO ("The Flocker") and is tasked with herding farm animals (sheep cows chickens and pigs) back to the mothership "The Mother Flocker". This is challenging due to the hazardous environments the animals exist in—the players must defend their flock against hungry predators avoid pits of death and send their animals flying with catapults.
