World 7 (New Super Mario Bros.)

World 7 is a world from the game New Super Mario Bros.. This world is set in the sky, and is made up entirely of clouds. To get to this world, the Player has to defeat Petey Piranha as Mini Mario. This is the first world in which Banzai Bill appears. The Boss is a Dark Lakitu called Lakithunder. Lakithunder is speculated to be behind the attack on Peach's castle in the opening movie.

7-1
The player will start on a hill. The first ? block on this level is a coin. The player jumps on a bar to go on a bar on part of 7-1.

7-Ghost House
In this level the player must hit the first of a row of Brick Blocks to release a ? Switch that will make five doors appear when hit. The top door contains what appears to be a solid fog and a Star Coin in the bottom left corner accessible by ground-pounding. The middle-left door contains 3 pumpkin enemies, a Star Coin and another solid fog - this time moving in waves. The Star Coin can be reached if the player jumps at the top of one of these waves. Neither the middle right door nor bottom left door are necessary, to finish the level or get all 3 Star Coins. The bottom right door leads to the exit. Inside is a group of pointing hands that direct the player to the moving box that contains a ? Switch. When hit, 2 moving platforms appear for a short time that bring the player up to the next door. In this new room, the player can hit a P Switch that for a short time turn the surrounding coins into solid platforms. Here the player can take a shortcut to exit the level by climbing a hidden vine to the left or take the standard route out to the right. The third coin is in a high platform at the top right corner of the room, accessible only to the quickest players. Once the player leaves the exit door they are at the black flagpole that ends the level.

7-2
The player will ride on a rising platform, stand to the left to go left and vice-versa.

7-3
The Player will be riding on a Giant Wiggler. When Mario uses a Starman here, he will leave a trail of Silver Coins.

7-Tower
It has rising and lowering platforms like in the first Tower.

7-4
This is a very short level, and consists of many mushrooms and Spin Blocks, similar to levels like World 1-3, but is a completely vertical level. There is only one enemy in the whole level, a Red Koopa Troopa. The first two Star Coins are above mushrooms, and the final one is within a trail of coins near the end. There is also a hidden area, with more Spin Blocks, and a P-Switch, giving Mario/Luigi many coins. After the hidden area is the flagpole.

Secret Exit
The secret exit requires Mario to be in his Mini Form, and hop onto a Flying ? Block, then jump around a pillar, and reach a mini pipe. Going into this will take the plumber to the secret exit, and go all the way to the castle.

7-5
This level is filled with Bullet Bills and Bob-ombs. Unlike most World 7 levels, this level takes place on an overworld area, and not in the sky. A Bob-omb is required to get the first Star Coin, above a set of bricks. The next Star Coin can only be accessed by Mini Mario, by using a Bob-omb to blow up the block guarding the Mini Pipe, and then enter it. In the hidden area, there are several Mini Goombas, as well as the Second Star Coin, blocked behind a pipe, and requires Mario to get the Mega Mushroom from a ? Block in the hidden area. The final star coin is in between several Bullet Bill cannons. After getting past some Banzai Bills at the very end, there is the flagpole.

Secret Exit
To get to the secret exit, Mario must blow up some blocks to get to another hidden pipe (which is not a Mini Pipe), and get to a hidden underground area, with about twenty coins. Another pipe will take him to several hills, and the Secret Exit. This will take Mario to World 7-A.

7-6
In this course the Player will have to take the secret exit to move on. If they don't, the path will lead back to World 7-4. To get to the Secret Exit, after walking on the Tall Mushrooms they have to hit the brick containing a Beanstalk, then go to a special stage.

7-A
This level is somewhat similar to a level in Pipe Land from Super Mario Bros. 3, and is mostly made out of pipes. It is also an underground level and has the only appearance of Squigglers in the game. All three Star Coins are accessed by pipes, the final coin being in a 'mini' pipe which only Mini Mario can enter. Completing the level is another way to reach the castle.

7-Castle
This level is based upon Snake Blocks, and is the first appearance of that object. The first Star Coin is near a set of spikes, the second Star Coin is on the "block" of a Ball 'n' Chain, and the third Star Coin is located at the end. This is the level in which the player fights Lakithunder.
