Super Mario Bros. 3/World 5

This is the Sky World. There are 2 sections of it, which will be explain in the Tower below.

5-1
If you have a P-wing, you can fly at the very beginning and enter a secret room that you can moonwalk through to get a music box, or enter another pipe at the end to get to an island with 4 1-Ups, as well as a P-switch that produces 2 giant 3's made of coins!

If you don't have a P-wing, you're going to have to go the regular route. Chain Chomps and Buster Beetles are the enemies in this level. A Nipper will be at the end of the level below the Goal Panel.

5-2
After entering the pipe, you can fall down for a while, but then you must climb back up to get to the next pipe to enter. Kill or avoid enemies as appropriate, and the next pipe takes you to a coin room with 3 1-Ups!

However, if you miss getting back up to the pipe, you're going to have to take a long, boring route. Furthermore, if you start out the level as small Mario, you will be forced to take this route, and your only power-up will be the super mushroom that you'll have to follow down the huge pit.

5-3
An exciting level that introduces the Goomba Shoe! To get it, you can kill a Goomba by breaking a brick that it stands on and the shoe is yours. However, you cannot get it by stomping on the Goomba; it will kill both the Goomba and the Shoe. There is a row of munchers that you can step on with a shoe, but will hit you otherwise.

Fortress
This fortress is recommended only if you think you'll get a game over and want to create a shortcut past 5-1 and 5-2.

If you're Racoon Mario or you have a P-wing, you can enter a secret pipe and get 3 1-Ups. The door at the very end takes you to Boom Boom's room.

Tower
The first floor of the tower deals with Rotodiscs and the second with Thwomps. In the third, if you have a P-wing, you can fly past the Pipe and get 3 invisible 1-Ups, but you must fly back to get into the pipe. The fourth floor is the challenge. The fifth floor is a dark room. The sixth floor has a Troopa, as well as a brick containing a blue vine that leads you to the exit pipe and into the exciting sky! You can get back to the ground by taking the pipe on the map, but to get to the sky again, you must re-do the tower.

5-4
A new sky level. If you're Raccoon or Tanooki Mario, you can take an easier route above. All of the levels for the remainder of World 5 have an exit pipe that will give you a Lakitu that if he tosses 4 Spinys, you'll get a 1-Up!

5-5
This level has Donut Lifts that you must try not to spend too much time standing on just one of them! One pipe covered by bricks that you can break if you have a tail will give you a Tanooki Suit! If you like it, try hard not to get any of the leaves near the end of the level.

5-6
Para-Beetles are in this side-scrolling level. Ride on them until the middle, and then search for a P-switch that will switch bricks and coins, and shortly after it is the exit pipe.

5-7
If you start the level with a Starman, you'll be able to get a few in this level. This level has a pipe that will take you to the ground. If you have a P-wing, you can get a number of bricks near the top of the ground part of this level.

(Variant: One block on the ground is white in the NES version, but blue in Super Mario All-Stars. The block's color was changed to prevent a glitch.)

Fortress
After entering the pipe, there is a room with a lot of lava. Try to avoid it. There's a starman in one of the ? blocks that you can use to avoid the Podoboos. The pipe at the end takes you to one more lava pit, and then to Boom Boom's room.

5-8
The main challenge is avoiding the Lakitu and Spinys before getting to the exit pipe.

5-9
A diagonally-scrolling level! Jump onto each elevator, avoiding the Fire Chomps, and get to the exit pipe.

Airship
The king has been transformed into a bird. This is a tough airship. Roy is very hard, If you hit on him 3 times, you'll get the wand and a letter from the Princess with a Jugem Cloud.
