You are a very funny little green alien and your goal is to get all the white sheep into the lab teleporter and send them home for future lab fun! You can do that by positioning your UFO above a sheep and quickly press the "SPACE" bar button to open the tractor beam. After that quickly again, point your UFO above the teleporter and again press the "SPACE" bar button to drop the sheep. Be aware! Your tractor beam will stay open only a few moments, so... hurry up!
