Frosty Cosmic Mario Race

Frosty Cosmic Mario Race (or Frosty Cosmic Luigi Race when playing as Luigi) is the fourth mission of the Freezeflame Galaxy in Super Mario Galaxy. Until the mission's completion, this mission can only be done while a Cosmic Comet is in orbit.

Layout
The only planet visited are the ice platforms of the Ice and Lava Platforms. Cosmic Mario will appear after taking a few steps forward and challenge the player to a race across the icy platforms. All the platforms are stationary, and like with the previous mission, the paths are split into three, with gravity flipping at the end of the first and second paths. The Power Star is placed at the end of the third path, though if Cosmic Mario makes it to the end first, the player will lose a life and have to start the race over.
