World 1-1 (New Super Mario Bros. Wii)

World 1-1 is the first level of World 1, and subsequently, of New Super Mario Bros. Wii.

Layout
In the beginning of the stage, just like in New Super Mario Bros., Princess Peach's Castle can be seen in the background. When the player starts, there are three ? Blocks, a few Brick Blocks, and a Goomba. The highest ? Block holds an item, a Super Mushroom for Small Mario, and a Propeller Mushroom for Super Mario. The player must move to the right to see a moving piece of ground. The first few blocks are in style of the first blocks in Super Mario Bros.. They should move farther ahead to find another moving piece of ground there. It has three platforms above it. It also has a green Pipe in it that moves around with it. The player can jump in it to collect coins and 1-Up Mushrooms and head out through the yellow pipe. If they are playing a Toad Rescue Mission a Toad should be yelling out from the ? Block behind them. The player can head forward to hit the Midway Flag. If they spin upwards using the Propeller Suit and go through the Red Ring, Red Coins appear for them to grab. They should then jump off the left side of the platform to find the moving piece of ground. There's a rolling hill and the player can stay in the compartment and get three 1-Ups and dozens of coins. The player is in a hidden area upon exiting. Just before leaving the hidden area there is a block, which they should hit to collect a 1-Up Mushroom. Continuing forward takes the player to the end of the level.

Star Coins

 * Star Coin 1: After the midway flag, over three ? Blocks. The player should use a Propeller Suit or a running jump to reach it.
 * Star Coin 2: At the end of the platform with the Red Coins, the player should spin to the next platform and then skip the following platform with the Red Koopa and collect another Star Coin.
 * Star Coin 3: They should then jump off the left side of the platform to find the moving piece of ground. A pipe moves around in this piece of ground, and when it comes by, the player should go inside of it. If the player goes in the pipe, they should wall kick up or use a Propeller Suit to collect the last Star Coin, then head out the yellow pipe.
