if you have been to the underground mines (don't know what it's called) you know how you get the blue balls (sorry forgot their name again) give it to the blue cloud (cloud sprite) at the Skytown skate park (I think this is what it's called) and it eats it (well, the virtual system says it eats it, but it doesn't show you [virtual system is not the right word, but what else should I call it?]) and you get coins.
Basicly, you give the blue balls from the mines to the cloud and it gives you coins.
