The Silver Stars of Sea Slide

The Silver Stars of Sea Slide is the third mission of the Sea Slide Galaxy in Super Mario Galaxy. The mission's objective is to collect five Silver Stars.

Layout
For this mission, Bee Mushrooms are placed around the galaxy, which the player needs to use to collect all of the Silver Stars. Collecting all of the Silver Stars will have the Power Star form and appear back at the player's starting area. The locations of the Silver Stars are:
 * The first Silver Star is on top of the stone arch where Guppy was found during the first mission; the player needs to use a moving cloud in order to cross the water.
 * For the second Silver Star, the player needs to use a cannon to blast to the Starshroom in the sky and use the Pull Stars to reach the Silver Star, followed by using a Sling Star to get back to the main land.
 * The third Silver Star is on top of a tree next to the stone tower. The player needs to use the Bee Suit to climb the tree and reach the Silver Star up high.
 * For the fourth Silver Star, the player needs to use the Bee Suit to fly up to the top of the large tree near the starting area.
 * The fifth Silver Star is located on the island in the center of Sea Slide Galaxy. To get there, the player needs to spin on a wheel located on a platform under the large tree. The wheel will cause a serpentine water slide to appear and lead to the island, where Penguru and the final Silver Star is placed.
