The Adventure of the Purple Coins

The Adventure of the Purple Coins is the second mission of the Clockwork Ruins Galaxy in Super Mario Galaxy 2. The mission is only playable if the player collected the Comet Medal in the Time for Adventure mission and when a Prankster Comet is in orbit.

The Purple Comet must be in orbit in order to select this mission. The player has to collect 100 Purple Coins scattered across the Giant Rotation Planet. The player has only five minutes to collect the coins, the longest time limit of any Purple Coin mission in both Super Mario Galaxy and Super Mario Galaxy 2. Unlike in the regular level, no enemies are present. This level can be time-consuming because the coins are on all sides of the millstones, and a few rotations may be needed before each one is done. After the player collects all the coins, the star appears on top of the fourth millstone.
