The basic premise of this game is that sheep were once intelligent beings from the planet Ovis Aries. These smart sheep sent a group of their species to Earth millions of years ago to learn about Earth's society and customs. Unfortunately their ship was damaged on the trip which left them stuck on planet Earth. As the years passed they forgot their mission, they soon became domesticated by mankind. Now their ancestors have come back to Earth to regain the lost sheep and stop the evil plan of mad scientist Mr. Pear. In order to keep their presence unknown they abduct 2 humans (Adam Halfpint and BoPeep) and 2 dogs (Motley and Shep) and implant them with the desire and will to herd sheep like mad men. The goal of the herders is to herd as many sheep as possible back to Mount Mouflon and return them to the sheep paradise of Blue Hawaii.
