World 2-6 (New Super Mario Bros. Wii)
From the Super Mario Wiki
World 2-6 is the sixth level of World 2 in the game New Super Mario Bros. Wii. This is a mushroom level that mostly has coins and blocks that sway left and right with the music. The player has to ride a pink block for the majority of the course. Flame Chomps make an appearance here.
As aforementioned, the player rides a pink block for most of the course. Near the end of the first path, there are four sets of moving blocks. There is a green Warp Pipe leading to an area with Bouncy Clouds and two Propeller Blocks. Around the midway point are a few platforms and another pink block; it goes a short distance until it stops at the flagpole.
The player needs a Propeller Suit or a well-timed jump off of a Flame Chomp to reach the red pipe in the sky near the end of the course.
