Follow That Shell!

Follow that Shell!, or Superstar Road-9, is the ninth and final course of Superstar Road in New Super Mario Bros. U and the last one overall in the game. It is unlocked when the player collects every Star Coin in Superstar Road.

Layout
The course is based off of the sky levels from Meringue Clouds. During the majority of the level, the player needs to use Koopa shells to break blocks and reach Star Coins.

Star Coins

 * Star Coin 1: When the stage begins, the player needs to throw the nearby Koopa into a cluster of Brick Blocks so the path to the Star Coin can be revealed.
 * Star Coin 2: Near the end of the stage, the player needs to throw a shell on to the brick platform. Mario can use a P-Switch before the shell reaches the point where the Star Coin can be collected by the shell.
 * Star Coin 3: Directly after the second Star Coin, the player needs to hit a block right below the final Star Coin. The block will release a beanstalk which will take the player to the coin.

Enemies

 * Koopa Troopas
 * Goombas
