World 5-4 (New Super Mario Bros. 2)

 is the fourth level of World 5 in New Super Mario Bros. 2. The area features many rising and sinking mushroom platforms, and is inhabited by several Koopa Paratroopas and Koopa Troopas.

Star Coins

 * Star Coin 1: There are two ways to collect the star coin:
 * 1. After encountering the Gold Ring, follow the mushroom's path. There is a Koopa on the right of the coin. Use the shell and throw it in the bottomless pit to get the star coin.
 * 2. Wall kick. This is dangerous since there is a gap on the right so slide on the left.
 * Star Coin 2: The player must stand on the pink mushroom platform immediately after the Roulette Block, which leads to a secret area in the sky with the Star Coin. If Mario jumps out of the pink mushroom platform, it is inaccessible. Raccoon Mario can also fly to the star coin.
 * Star Coin 3: The third Star Coin is found floating over an abyss between two blue mushroom platforms. The player can either bounce off the Paratroopa, or use a Koopa Troopa's shell to collect it.

Enemies
