Gusty Garden's Gravity Scramble

Gusty Garden's Gravity Scramble is the third mission of the Gusty Garden Galaxy in Super Mario Galaxy. The mission's objective is to navigate a structure where gravity is in flux.

Layout
Like with the previous missions, the player starts on the starting planet and has to use the Floaty Fluffs to move between from one planet to the next. On the next planet, the player has to defeat a Piranha Plant to cause a vine to grow, which will allow the player to reach the above planet. Again, the player must defeat a Piranha Planet to cause a vine to grow, though this one will send Mario into a Launch Star to reach a planet with several boulders. On the opposite end of the planet is a Launch Star that will take the player to three large disks where they need to collect five Star Chips while avoiding Amps.

The Launch Star that appears upon collecting the Star Chips will take the player to a large structure made up of several moving blocks. The player has to spin into arrows to change the flow of gravity, indicated by the platforms with an exclamation point on them; dark areas and platforms with a question mark indicate where gravity is not active. The player needs to constantly change the flow of gravity to navigate the structure while avoiding cannonballs and blocks that can push Mario over the edge. At the end of the structure is the Power Star, trapped in a large crystal.

Trivia

 * In this mission, it is possible to fall back onto the final Disk Planet with the Launch Star by performing a Long Jump in the right place. However, because the gravity has now changed on the ! and ? Planets, it then becomes impossible to complete the level.
