Hint: Wobbly Bobbly: Ball lobbing:
In the ball lobbing game you encounter in Wobbly Bobbly, where you are a little man and have to lob a ball as far as possible, make sure you time it exactly right. The best time to lob it is when the little man's arm is just about to go over his shoulder, or when his hand just reaches his head. By doing this, the ball will not go behind you or slam straight to the ground.
