Bowser's Big Bad Speed Run

Bowser's Big Bad Speed Run is the second mission of Bowser's Galaxy Generator in Super Mario Galaxy 2. This mission will become available if the player collected the Comet Medal in the previous mission and when a Prankster Comet is in orbit.

Mission
In this level, the player will play through the previous mission once again, though the Speedy Comet must be in orbit. The player will only have approximately thirty seconds to complete the level at the start, requiring Mario or Luigi to collect clocks to increase this time limit by ten seconds each. The Checkpoint Flag in this level is the only checkpoint in a Speedy Comet in the entire game.
