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, which is an obvious reference to the levels in Toy Time Galaxy from the first game. However, the spinning platforms are replaced with Flip Switches. 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.

8-Bit Mario Planet
This planet serves as the starting planet for most of the missions. The planet is shaped exactly like a sprite of Mario from Super Mario Bros. The green pixels are disappearing platforms, the orange pixels are lava, and the yellow pixels are Flip Switches. The Comet Medal is found at the bottom left of the planet. The only enemies here are Burn Bits.

8-Bit Luigi Planet
This planet only appears in the "Luigi's Purple Coin Chaos" mission. The planet is shaped exactly like a sprite of Luigi from Super Mario Bros. The green pixels are disappearing platforms and poisonous water while the yellow pixels are solid yellow platforms. One hundred Purple Coins are found on this planet. The only enemies here are Cosmic Clones.
