World 5-6 (New Super Mario Bros. 2)

Star Coins

 * Star Coin 1: Just before the checkpoint, the Star Coin is seen to the right of the spinning platforms and above spiked platforms. The player must hit the red switch to safely collect this coin.
 * Star Coin 2: After the checkpoint, Mario or Luigi must find a green pipe that'll take them underground to a room with the star coin. The player needs to use a springboard to reach it.
 * Star Coin 3: Just before the flagpole, the star coin is buried underneath stone blocks. The player can only collect it with the Mega Mushroom.
