More water?! To get to Course 9, go through the castle's main door and through one of the wooden doors to the side of the main staircase. Go down the staircase in the next room and through the door. Head left: you will see a big Star Door. Go through it and jump into the film of water blocking the corridor. This is Course 9: Dire, Dire Docks.

You need 30 Stars just to get into Course 9. What a gyp!
