This is a really cool map - a giant amusement park! There are rides, roller coasters and everything.

For the first episode, go right into the entrance of the park and straight ahead to see shadow mario. You'll be put on the rollercoaster and all you can do is ride around the track and shoot. Either you shoot water normally (you can turn around in your seat) or sometimes you'll get a rocket you can fire.

Missiles will come at you. Face forward most of the time since you'll get a warning if one comes up from behind but no warning if they are in front of you. As you go past the bowser head, fire rockets at his head. Once you blast him, you'll see a cute scene. It's really baby bowser!! He thinks Princess Peach is his Mom (Ummmm wouldn't she know it if she had a Bowser-baby??). So he's trying to rescue her from you. He now takes off to Corona Mountain, in essence the final boss battle that you get to at the end of the game.

The shine is in the water fountain.
