While exploring a desolated island you fell and have become Trapped In A Well. Unfortunately you don't have anything to climb up with, so you have to stay there hoping that somebody will rescue you. But while you are waiting for help you have to eat so that you can survive. The only food you can find are the sea gulls flying over the well. Throw rocks at the sea gulls and get them to fall inside the well so you can have some lunch.
