The Perfect Run

The Perfect Run is the second mission of the Grandmaster Galaxy in Super Mario Galaxy 2, and is subsequently the final mission of the game. This mission can only be played after two conditions have been met: the player needs to have collected the Comet Medal from the previous mission and the player needs to have 9,999 Star Bits stored with the Banktoad. Completing both conditions will cause the Prankster Comet to appear, allowing the player to player the mission. Music from Super Mario Galaxy also plays during this mission.

Mission
This mission layout is mostly the same as the previous one. However, the Prankster Comet will cause the player to have to do the mission with only one health. There are also no Checkpoint Flags, meaning the player will have to start the mission over if they take damage. The planets and areas mostly remain the same, with the only major differences being Choppahs and additional Floating Mines added to the first area. If the player manages to defeat the Boomerang Bros. at the end, a Launch Star will appear that will send the player to the Gate Planet, where the player will meet with Rosalina, who rewards them with the final Power Star. Afterwards, Rosalina can be found on Starship Mario.
