Click the B key to make scratch grow, and S to make him shrink. Click space to play a loud sound and make scratch change colour. When scratch is in the top 25% of the screen he says 'I like it up here'. When he touches red he plays a low note, and when he touches blue he plays a high note. When Scratch gets too close to the dog, the dog runs away. When Scratch collides with the soccer ball he says 'excuse me'. Use the arrow keys to move Scratch.
