Flipswitch Galaxy

The Flipswitch Galaxy is a very small galaxy in the game Super Mario Galaxy. The Galaxy is composed of a set of panels 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 screenshots.

Painting the Planet Yellow
In this level, Mario has to step on every blue panel at least once in order to change their color to yellow. There are some spiked platforms Mario has to cross. After turning all the platforms yellow, they turn green and Mario can step on any of them without worry of changing their color. Then, Mario has to use the spring-necked robot on the top of the planetoid to get the Power Star.
