Every window cleaner dreams about the lucky day, when he will see a beautiful girl in the next window, undressing just in front of him... and she will invite him to enter through the window... And you may materialize his dreams. Catch his "bubble-dream" about some girl, then test your luck and collect 21 (Black Jack) of bubble-numbers, and undress this girl of his dream. More, you may even enter her room, and she will satisfy your imagination!
