Flash Black Galaxy
Flash Black Galaxy is a galaxy appearing in the game Super Mario Galaxy 2. Located in World 6, the galaxy takes place in a large mansion. However, everything is pitch black except for the occasional second of lightning, which illuminates the area. The lightning occurs after every eight beats of the music's rhythm, similar to Beat Block Galaxy, with the same music from that galaxy being used. In addition, there are many gaps in the ground. Yoshi is found here and the level makes extensive use of the Blimp Fruit. Common enemies and obstacles here include Mines, Jack O'Goombas, and Flaptacks. The galaxy's name "Flash Black" is a pun on "flashback" and "black", since most of the time the galaxy is black to the point where it is invisible to the eye until it flashes like a camera.
NOTE: Unless otherwise noted, all names are unofficial.
The starting planet is a large, dark tower containing a maze. The exterior design of the planet resembles the Ghostly Galaxy of the first game. To reach its top, Mario must use Blimp Yoshi to float upward while avoiding the Mines and the other enemies. The Launch Star is located at the top right of the tower. The Comet Medal is found on this planet as well. Enemies here include Jack O'Goombas and Paragoombas.
Maze Walkway Planet
This planet is a dark maze with rings of Octoboos on it. Mario must walk carefully to avoid Flaptacks and falling off the platforms. There are five Silver Stars on this planet.

If the players go to the Maze Planet in any of the missions and look at the back of the maze, they will see a large windmill.
