Flipswitch Galaxy

The Flipswitch Galaxy is a small galaxy, having only one mission, in the game Super Mario Galaxy. The Galaxy is composed of 18 Flipswitch Panels which Mario must step on. After all of them have been turned yellow, a Power Star appears. The background is a scene from Super Mario Bros., as shown in the pictures. They periodically switch between variations of and. Even though the level sounds simple, a Sentry Beam spawns out circle shaped lasers which can damage Mario. Some Flipswitch Panels are also covered with moving spiked platforms that can hurt Mario.

Starting Planet
The Starting Planet is the largest planet in the Flipswitch Galaxy and the only accessible one. It is covered in Flipswitch Panels (18 of them exactly) and several hazards such as spiked platforms and electrical barriers. The platforms and electrical barriers move around the planet creating hazards for Mario to dodge as he goes through them.

The only other resident of the planet is a Sentry Beam that releases laser shockwaves as Mario goes through the planet. Mario must flip all the Flipswitch Panels from blue to yellow and then, when they are all flipped, they will turn green. Once the Flipswitch Panels are green the laser-shooting Sentry Beam will turn into a trampoline and release a Power Star for Mario to get. The electric barriers and spiked platforms will also be deactivated.

Block Planets
These breakable block planets are seen when Mario is flying to the galaxy and cannot be reached (except through hacking). These aren't really planets but rather Brick Blocks floating in space. Each of these blocks contain one coin.

Mission
This Galaxy only has one mission. The objective of this mission is summarised in the below table.

Trivia

 * At random intervals in the galaxy, the backgrounds will change from level to level from the original Super Mario Bros.
 * The Flipswitch Galaxy is the smallest galaxy in the game.
 * The music used for this galaxy (as well as many other galaxies), which is a cover of the underground theme from Super Mario Bros., was reused and slightly remixed as the underground theme in Super Mario 3D Land and Super Mario 3D World.
