World 3-2 (New Super Mario Bros. Wii)
From the Super Mario Wiki, the Mario encyclopedia
World 3-2 is the second level of World 3 in New Super Mario Bros. Wii. This snow-covered level marks the first appearance of Bullet Bills and Bill Blasters in the game and introduces a new variant of Hammer Bro, the Ice Bro. Its completion unlocks World 3-3, World 3-, World 3-, and an Enemy Course.
World 3-2 is the third level in the game in which Yoshi is available to ride.
The stage starts with snow-covered hills patrolled by Goombas and three Bill Blasters, along with the first Star Coin. The next area has an Ice Bro, more Bill Blasters and a Block containing a Super Star. Located nearby are platforms with coins and a Yoshi Egg. The players then pass through an area infested with Bill Blasters and moving platforms, after some Brick Blocks, followed by the flagpole.
