The only key you have to press is up arrow. Once you do that, everything else is done automatically. If you're tired of watching him dance, then hit up arrow. It will take you back to the home screen. hit up arrow again to have him start dancing
This was originally supposed to be an animation of a ninja fighting somebody. However, once I played the first 7 frames, it looked a lot like he was dancing. And that's how the dance animation was made.
