World 1-1 (New Super Mario Bros.)

World 1-1 is the first level of World 1 in New Super Mario Bros.

Layout
The level takes place in a meadow with flowers, bushes, and mushrooms scattering the land. Peach's Castle is visible in the background for the first portion of the level. The level introduces the Goombas and Koopa Troopas with both red and green shells. It also introduces the Mega Mushroom.

The first ? Blocks that Mario encounters have two coins in them, and one that has a power-up. Going on into the level, Brick Blocks appear. The top one contains fourteen coins and a Super Mushroom. The one underneath that one contains one coin, while the rest are simple Brick Blocks. Mario then encounters a Goomba, found next to a Pipe. The Pipe cannot be entered, however. Mario encounters another Goomba shortly after. Then, Mario jumps over a pit while collecting coins. A block is found about one-third through the level, and a Mega Mushroom is encountered for the first time, making Mario become Mega Mario, destroying everything in its path. However, if the player chooses not to get the Mega Mushroom, they should keep advancing. The player now sees their first Star Coin. There are some Koopa Troopas and a Goomba in this area. There is also a hidden vine that leads to the sky with Red Coins. It is located inside a Brick Block where the Red Koopa Troopa is walking. The pipe that's currently visible to the player leads to an underground room with the second Star Coin in it, and a power-up. The player sees three Brick Blocks with coins in them, but if the player jumps on top of the middle Brick Block, a Star comes out of it. Another ? Block is here, this time containing a power-up. A set of Brick Blocks is blocking the third Star Coin; the player has to ground pound it to break it and get the Star Coin. Another ? Block is here, containing a single coin. A couple of Goombas and Koopa Troopas appear in this area, along with Brick Blocks and Coins. The player encounters the flagpole, and can finish the level. They gain access to World 1-2. There are a few vines leading to platforms and other things and a Super Star is found above a Brick Block before the end of the level.

Star Coins

 * Star Coin 1 - Found atop a ledge of blocks. Mario or Luigi will either have to jump off the blocks or be in Mega form to get this coin.
 * Star Coin 2 - Found in the second pipe after the first star coin. The player will need to avoid destroying it with the Mega Mushroom.
 * Star Coin 3 - Mario and Luigi will need to Ground Pound some Brick Blocks to obtain this Star Coin.
