Megahammer's Daredevil Run

Megahammer's Daredevil Run is a stage that appears in Super Mario Galaxy 2. It can be accessed by gaining the Comet Medal in its base mission plus another 26 medals in other galaxies's first missions (27 total). This causes a Daredevil Comet to visit Bowser Jr.'s Fearsome Fleet.

Layout
Mario has to beat Bowser Jr.'s mighty Megahammer again, but without taking damage. The only planet visited is the Megahammer Planet. Yoshi is required for this mission, and the Megahammer retains his attack pattern from before.

Trivia

 * The mission's name is erroneously written "Megahammer's Daredevil Bash" in the game.
