Mario can get the last Star Coin by going through a red Warp Pipe near the end of the level. After the final Star Coin is the flagpole.

Star Coins

 * Star Coin 1 - Mario should use the falling platforms to reach the first Star Coin.
 * Star Coin 2 - After the midway point, the second Star Coin is below a rock formation. Mario will need to go underwater and under the formation while avoiding the Spike Bass. The Star Coin is easier to collect if Mario defeats the Spike Bass.
 * Star Coin 3 - After hitting the P Switch, Mario should run all the way to the end of the level and jump into the red pipe. Mario will fall on the Star Coin and appear next to the flagpole.
