click the N on the opening screen on Grundos space outfit...

it gives you a special grundo zurroball.

Tip 1: If you click the top of the ball when it's first idle waiting to be hit, it won't go so high, it will go down, just make sure you still hit it!

Tip 2: On the 'floor' of the screen, there's a shadow of the ball, use that to watch where your ball is going.
