'''World 1-1''' is the first [[level]] of ''[[New Super Mario Bros. Wii]]''. It begins immediately outside [[Peach's Castle]] and introduces the player to rolling hills and a new power-up, the [[Propeller Suit]]. Its completion unlocks [[World 1-2 (New Super Mario Bros. Wii)|World 1-2]].

Princess Peach's Castle can be seen in the background at the beginning of the level, just as in ''[[New Super Mario Bros.]]'' There are also three [[? Block]]s, a few [[Brick Block|brick]]s, and a [[Goomba]]. To the right are some moving sections of land, the latter of which has three [[platform]]s above it, and a [[Warp Pipe]] within it that leads to a room with [[coin]]s, bricks, and a [[P Switch]]. The [[Checkpoint Flag|midway point]] can be found after exiting the sub-area.

If players have the Propeller Suit, which is accessible in several ? Blocks, they can access a [[Red Ring]] on a platform in the air to collect a [[1-Up Mushroom]]. Further along is a rolling hill with a secret alcove; if the player [[jump]]s onto the pipe and waits, they are brought to an area with three hidden 1-Up Mushrooms and lots of coins. The pipe itself leads to an area with a [[Star Coin]]. After the player jumps over a few [[pit]]s, the [[Goal Pole|pole]] can be seen past the last rolling hill.

*'''Star Coin 1''': The first [[Star Coin]] is just after the midway point, floating above two coins and a row of two bricks and a ? Block. Mario and co. can use a Propeller Suit to fly up to it or jump from the nearby hill.

*'''Star Coin 2''': There will be a spinning ground wheel with a green Warp Pipe submerged inside. After Mario and co. enters the pipe, the second Star Coin is floating high in the air between two pipes with several coins surrounding it. Mario and co. can again reach it with a Propeller Suit, or by [[Wall Jump|wall-kicking]].

*'''Star Coin 3''': Shortly after Mario and co. exits the area with the second Star Coin, the third Star Coin is floating high in the air over a platform. Mario and co. must obtain it either with a Propeller Suit or by using the nearby [[Koopa Troopa]] to jump to it.
