Layout
For this mission, five Silver Stars are scattered around Wet-Dry World. In order to collect all the Silver Stars, the player has to raise and lower the water levels accordingly. The locations of the Silver Stars are:
 * Behind the long ramp. The course needs to be at least halfway filled with water to reach it.
 * In a Brick next to the starting area. The water needs to be completely drained to break the Brick.
 * On the large stone platform near the starting area. The player needs to use the Purple Switch on the bridge to reach it.
 * On one of the platforms next to the Arrow Lifts. The water level needs to be at least halfway full to reach it.
 * Above the central black circular platform above the town. The stage cannon or Mario's Power Flower ability is needed to reach it.

Once all the Silver Stars are collected, the Power Star will appear in the Star Sphere on a platform that can be reached only when the water level is raised to its highest.
