World 5-1
This is the first level to feature strong winds. The player will see four ? Blocks containing coins along with Buzzy Beetles. Then, the player will see a red Piranha Plant coming out of the pipe. The player will now have to jump from gap to gap while avoiding Piranha Plants. After, the player should see a Koopa Paratroopa. Two Bill Blasters and three Koopa Troopas will be here. Another Piranha Plant and a Koopa Paratroopa will appear. The player can go down the first pipe shown here, which will lead him/her to a Bonus Room. The player will have to run and jump to get on top of the second pipe here, while avoiding a Koopa Paratroopa. Three Goombas and another Red Piranha Plant will be shown here, and this is also the exit of the Bonus Room from earlier. The player will climb the staircase, and a heavy wind will start blowing the player. He/She must jump from gap to gap to reach the other side of the level. The wind will now stop.

A Bill Blaster and two Piranha Plants will come in the player's way. Three Piranha Plants in pipes protruding slightly above the ground and a Koopa Paratroopa will appear. Then, a Buzzy Beetle and two Goombas will walk by the player. Three coins can then be seen floating in the air, with a Red Piranha Plant underneath the coins. As the player advances, he/she will meet up with three more Koopa Troopas, another Piranha Plant, and another set of three Koopa Troopas. The player will need to jump from the block on the ground to get to the staircase. He/She will also have to use the Koopa Paratroopas over here and bounce off them to reach the other side. Eventually, the player will see a set of Brick Blocks with Koopa Paratroopas on each side. If the player hits the topmost right one, a Vine will appear, which will lead the player to Coin Heaven and also a Warp Pipe to World 6. If the player advances forward, he/she will find two Koopa Paratroopas and also two Hidden Blocks, which will serve as a staircase to the stone blocks high above the player. The player will advance, and a Piranha Plant, along with the Flagpole will be seen. Slide down the Flagpole to enter World 5-2.

If the player jumps over the Flagpole, and continues forward, he/she will eventually reach the World 6 warp zone.

World 5-2
The player will be in an underground level. A couple of Piranha Plants and a Koopa Troopa can be seen here. The player will have to jump to reach the ? Blocks, in which five of them contain coins and one contains a Poison Mushroom, and a set of Koopa Troopas. The player will see a lone Piranha Plant, and could choose to go either Up or Down. The Up route contains coins, while the down route will contain a Brick Block with a power-up inside of it. After the routes merge together again, a Brick Block with a Star inside of it, a Piranha Plant, and two Buzzy Beetles along with a Koopa Troopa will be in this area of the level. The player will see another Piranha Plant, and the top right Brick Block from the pipe it's on contains a 1-Up Mushroom. A couple more Piranha Plants and a lone Koopa Troopa will be set here. The player will now see a multiple Coin Block hidden in the left Brick Block, and another Vine which will lead the player to a Warp Zone which will lead him/her to World 8 on the lone rightmost Brick Block. The player will now have to jump from a row of moving platforms that will move either up or down continuously and can either take the route that leads up, which will lead the player to yet another Warp Zone that will lead him/her to World 7. Or, the player can take the normal route while collecting coins and facing a couple more Piranha Plants. The player will now see the exit pipe, and then will be outside. The player will climb the staircase and will see the Flagpole here. Slide down it to open up World 5-3.

World 5-3
The player will see an automatic platform that will carry the player across the level. The player should stand on it. A Piranha Plant can be seen to start off. The player will eventually see two Koopa Paratroopas, and a pipe that will lead the player to a Bonus Room, and also the next area of the level. He/She will then see a Blooper floating in the air, along with some Blocks and a Koopa Paratroopa. Two Piranha Plants can be seen on the ground. If the player did not take the exit to the next area of this level, then the area will repeat until the player does so.

In the next area of the level, the player will see two Piranha Plants, and Bullet Bills will be shot off the screen. The player will then see two platforms that are connected together with a coin on top of one of the platforms, and a platform protruding from the ground that will contain more coins. Another Blooper will be seen here, along with a moving platform. The player will need to bounce off the Koopa Paratroopa over here to reach the platform with coins. The player will then need to hop across 3 platforms, which will fall to get onto another platform. He/She will now see two platforms connected to each other, with two coins on each of them, and two Blocks along with the Flagpole. Slide down the Flagpole to reach the final level in this World, which is World 5-4.

World 5-4
The player will start off by seeing a platform that will fall down if he/she steps on it, along with some Podoboos and a firebar. The player will see more firebars, and a Brick Block over a firebar which will contain a power-up. Now, the player will jump from ledge to ledge, and will be on a platform, which will have a firebar that the player must avoid. The player can then take two routes here; either go up and collect coins while avoiding a Podoboo, or jumping from platform to platform while avoiding a Podoboo. Another firebar will be set in this area. The player must jump from Block to Block while avoiding two Podoboos to cross the lava. Some Firebars can be seen here.

The player must now avoid two Podoboos and a huge firebar by cautiously advancing from block to block. False Bowser will now start shooting fireballs at the player. If the player doesn't have a power-up, he/she can safely walk under the firebars seen here, however if he/she does not, then the player must carefully make his/her way across these two firebars. False Bowser along with a Podoboo, a lot of Brick Blocks, and a moving platform will be here. After the player touches the Ax, or defeats the Lakitu which is in disguise as Bowser with fireballs, he/she will rescue five Mushroom Retainers, and will have access to World 6-1.
