Flipswitch Galaxy

The Flipswitch Galaxy is a rather small galaxy having only one mission in the game Super Mario Galaxy. The Galaxy is composed of a set of Flipswitches which Mario must step on. After all of them have been touched, a Power Star appears. The background is a scene from Super Mario Bros., as shown in the pictures. Even though the level sounds simple, a robot spawns out circle shaped lasers which can damage Mario. Some Flipswitches are also covered with moving spiked platforms that can hurt Mario.

Flipswitch Planet
This Planet that Mario starts and ends on is covered in exactly 18 Flipswitches. It contains a Robot that releases circular lasers, some spiked platforms, and a few electrical barriers. Once the player steps on all the flipswitches, turning them yellow, then a Power Star will appear, and the barriers and platforms will be deactivated.

Block Planets
These breakable block planets are seen when Mario is flying to the Flipswitch Planet and can't be reached without hacking.

Painting the Planet Yellow
In this level, Mario needs to step on every blue Flipswitch so that they all wind up being yellow at the same time. Due to the layout of the level, it is likely that Mario will need to step on certain Flipswitches more than once in the process to turn all of them yellow. There are also some spiked platforms Mario has to cross. After turning all the Flipswitches yellow, they will turn green and the Power Star will appear. Mario then has to use the spring-necked robot on the top of the planetoid to reach the Power Star.
