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

World 6-5 is the fifth level of World 6 in New Super Mario Bros. Wii. This is the only recommended level in Free-for-all mode to have a hidden goal.

Layout
The level begins with a Porcupuffer chasing Mario throughout the level. The first Star Coin can easily be obtained by getting on a ? Block or swimming to get it. Then the water starts frequently rising and draining. After the midway point, the Mario can get the second Star Coin which is on a low platform. Next, there will be four ? Blocks. If Mario jumps in between the second and third ones, an Invisible Block with a vine appears, giving access to the third Star Coin and the hidden goal. After the vine, Mario must enter a Warp Pipe to the pole finishing the level.

Star Coins

 * Star Coin 1: The first Star Coin is floating atop a Mega ? Block near the beginning of the level.
 * Star Coin 2: The second Star Coin is in plain sight shortly after the midway point.
 * Star Coin 3: Soon after the second Star Coin are four Mega ? Blocks. In the middle of them is a hidden vine. After climbing up it, Mario and co. must grab the Propeller Block and use it to fly up to the third Star Coin at the end of the area.

Hidden goal
The player must follow the aforementioned path to the third Star Coin for the hidden goal. This exit will take the player directly to World 6-Castle.
