Red Stars are power-ups in Super Mario Galaxy. Red Stars transform Mario into Flying Mario (Luigi into Flying Luigi). They wear off over time, and are only found in the second mission of the Gateway Galaxy and in specific spots of the Comet Observatory. They are unlocked for use in the Observatory after Mario obtains the Red Power Star in the second mission of the Gateway Galaxy. In this mission, Mario must collect one hundred Purple Coins for the Red Luma to make Red Stars available for use. Its ability also appears in Super Mario Galaxy 2 through hacking, but the ability is never used, nor is it seen in the game. The Red Star itself never appears in the game.
