The Electric Labyrinth

The Electric Labyrinth is the only mission of the Bubble Blast Galaxy in Super Mario Galaxy. The mission involves using a bubble to traverse obstacles.

Layout
The player starts on a star-shaped planet with five pipes. The player must go through the challenges on the other side of each of them in order to collect all the Star Chips, with all the areas being surrounded by electric rails. Upon collecting the Star Chip in the area, the player can use a Sling Star to return to the starting planet. After collecting all five Star Chips, a Launch Star appears to take the player to the next area.
 * The pipe on the top leads to an area with three rotating walls, which act as obstacles that can push the player into the electric rails.
 * The pipe to the left leads to an area with moving electric rails the player must navigate around.
 * The pipe to the bottom-left leads to an area with Fire Shooters. The Sling Star is strangely placed behind the pipe into the area, making its use rather redundant as the player can simply just go back through the pipe.
 * The pipe to the bottom-right leads to an area with many moving Amps.
 * The pipe to the right leads to an area with many Space Mines, which the player must navigate around.

The second half of the galaxy is a long path with Bullet Bills being fired out of a Bill Blaster, along with many Space Mines and moving walls. Near the end of the challenge is a row of Bill Blasters that will fire Bullet Bills in a condensed area. At the end of the path is the Power Star.
