World 4-2 (New Super Mario Bros. Wii)
World 4-2 is the second level of World 4 of New Super Mario Bros. Wii. Like with several other levels in the game, the player has the option of playing World 4-3 as opposed to this level, the completion of both levels result in the same path being accessed.
A lot of this course is filled with Donut Blocks and Cheep-Cheeps that will jump up to attack the player. To get one of the Star Coins, Mario has to stand on a long falling platform with the Donut Blocks' coloration.
