Farmer Bob is a simple dairy farmer who has spent his years laboring away on his small farm. As time went on, business grew slower and slower as dairy products began to ship in from other planets, so Farmer Bob decided to take his small operation to an interplanetary scale. After investing in a small spaceship, fueled on the abundance of cow farts he already had, things finally began to look up.
Unfortunately, one night while Farmer Bob was sound asleep, space parasites that feed on cow farts arrived on Earth. No one knows where they came from, but they collapsed Earth's dairy industry in all but a day. Farmer Bob's cows fled across the Milky Way. Help him find his cows, and fast, before the whole galaxy is devastated by these dangerous creatures.
