Luigi's Purple Coins

What is that?
"Luigi's Purple Coins" is a level in Super Mario Galaxy in which the player must collect 100 of the 150 Purple Coins on reverse side of the 8-bit Mario planet, which looks like 8-bit Luigi, within the three minute time limit. The lava is replaced with Poison Swamp, Flip Tiles, and Shrinking Tiles. If Mario manages to collect 100 purple coins, he must make it back to the start to collect the Power Star. It has been officially labeled the hardest level in the game.
