Passing the Swim Test

Passing the Swim Test is the second mission of the Beach Bowl Galaxy in Super Mario Galaxy. The mission's objective is to bring the Gold Shell to the Coach.

Speaking to the Coach will have him tell Mario about the final swim test, and bringing him the Gold Shell will reward Mario with an "automatic A." The Gold Shell is being carried by another penguin in the water, and spinning when nearby will take the shell from him. Simply bringing the Gold Shell back to the Coach will reward the player with a Power Star. Should the Gold Shell get lost or destroyed, it will respawn back at the penguin that was carrying it originally.
