Farmers Versus Aliens

Your farm in Farmers Versus Aliens is under serious threat from outer space. For some reason, aliens from a distant galaxy decided to kidnap animals from your farm, and this is not at all good. Nothing can explain the loss of living creatures; who will believe that aliens stole cows, sheep, pigs and horses. You will have to hide them and to do this you must help the farmer drive each animal into a green triangular area on which the corresponding animal is drawn. This will hide all your living creatures from the eyes of aliens. But hurry up, otherwise they will start Operation Farmers Versus Aliens.
