In this game, Alice is searching for a key to fit into the padlock. There are three other worlds she visits by clicking on different animals in the array visualization. 1) an island world that says "Sorry, no key here", 2) an ice world in which the penguin skates around the ice when clicked on, and 3) a desert world, where the key is hidden. When the item under which the key is hidden is clicked, Alice moves to the key and then to the original world, the key moves to the padlock, and then a sign appears saying "you won!!"
