A hundred fifty Purple Coins are scattered around the Puzzle Cube planet, and the player has two minutes and thirty seconds to collect at least a hundred of them. Once a hundred of the Purple Coins are collected, the Power Star will appear back at the starting area with the fountain, and the player has to make it back within the time remaining.
