Purple Coin

Purple Coins are very special Coins that appear in Super Mario Galaxy. They will most often appear when a Purple Comet is in orbit of a Galaxy.

The player will always need to collect one-hundred Purple Coins to make a Power Star appear. Purple Coin Missions sometimes have a time limit. When there a is time limit, the Purple Coins are usually either set along a linear path, or one-hunrded and fifty will appear and only one-hundred of them need to collected. Additionally, once the Power Star appears, the player must collect it before the remaining time runs out.

In missions that aren't timed, the Purple Coins will be spread out across the level, requiring the player to explore every area in order to find them all.

There are two Purple Coin missions that are not activated by a Purple Comet. One in the Gateway Galaxy and another in the Grand Finale Galaxy.
