What exactly are Purple Coins?
The Purple Coins (Purple Coins) are special items introduced in Super Mario Galaxy and then in Galaxy 2. Unlike the yellow coins, they grant neither lives nor health; they only appear during the “ Purple Coin ” missions, unlocked once Bowser has been beaten in the final showdown (“The Fate of the Universe”).
