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.

Planets
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
The starting planet is a large, dark tower containing a maze. 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. This planet resembles the Dark Hopper Planet D in the Matter Splatter Galaxy of Super Mario Galaxy.

Green Star 1
This Green Star is located in the top-right corner of the tower on the first planet. Mario must either use Blimp Yoshi to reach it or sideflip then Flutter Jump with Yoshi.

Green Star 2
This star is located on the Maze Planet. Mario has to make his way to the end of the planet to notice the Green Star floating below. He has to fall carefully to catch it.

Prima Official Game Guide description

 * "Darkness reigns in this spooky galaxy. Every few seconds, lightning crackles across the sky and reveals the architecture of a haunted mansion and a maze of platforms out over empty space. Use those flashes so you aren't stumbling around in the dark."

Trivia

 * 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.
 * 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.
 * The exterior design of the starting planet resembles the Ghostly Galaxy of the first game.
 * The player can use the Infinite Flutter Jump glitch to land on the roof of the Mansion Planet in this galaxy.
