For a certain number of minutes you will be reincarnated as one of the evil birds, collect three stars, and his girlfriend, and then go home. This should be done as quickly as possible, because the bird house doors are closed exactly one minute from the start of game Angry Birds: Saving the eggs. Do not loiter not minutes, carefully think over all his way not to make unnecessary steps in the wrong direction for you. If you try to come home without the stars in front of you just shut the door and the job is not counted.
