Mario Squared Galaxy

Mario Squared Galaxy is a galaxy appearing in the game Super Mario Galaxy 2. It is located in World S. The galaxy takes place on an 8-Bit Mario, almost exactly like the one in Toy Time Galaxy from the first game. However, the spinning platforms are replaced with Flip Switches. Mario will need to turn all the Flip Switches yellow to gain the star. The only enemies here are Burn Bits. An 8-Bit Luigi appears on the opposite and serves as a Purple Coin level. It keeps it trademark poisonous water, but this time, the platforms don't spin and there are only 100 Purple Coins in the mission. Cosmic Clones appear during said mission.

Make Mario a Star
To complete this mission, Mario has to activate all of the Flipswitches found on the starting planet to make a complete 8-Bit Mario. When done so, a Power Star will appear on a brown platform.
