The level contains eight sections divided up into the main area and subarea. Each can section has a Key Door at the end, but another method to reach the next section. After going through the sections, the Goal Pole is seen nearby, with Big Dry Bones on bridges to help the player get a 1-Up. There is also a Hidden Block containing a 1-Up Mushroom on the Warp Pipe here.
In Section 1, the player needs to avoid a Green Koopa Paratroopa with the Key nearby. After climbing Semisolid Platform, the player can enter the Key Door. But, if the player does not want to enter the Key Door, the player needs to Jump twice but not Spin Jump on the Koopa Paratroopa and toss it at a Brick Block to activate a Vine. This helps getting down due to the Spike Traps.
In Section 2, the player needs to get past Thwomps and jump into the Key. There is a ? Block containing a Super Mushroom to the left of the Key Door from Section 1. The player also can Spin Jump on the Thwomps. Doing so on the third one allows the player to go to the next section without the Key Door.
In Section 3, the player needs to climb Brick Blocks and Hard Blocks guarded by Spike Tops to get the Key for the Key Door on the other side. There is also a P Switch nearby to remove the Spike Tops on Brick Blocks. To get to the next section without the Key Door, the player needs to get past Spike Traps by taking damage or using a Spike Top to Spin Jump on.
In Section 4, the player needs to get a Key then Key Door that a Big Chain Chomp is guarding. To get to the Warp Pipe without the Key Door, the player needs to Ground Pound the Big Chain Chomp's post. Also, near the Warp Pipe is a Hidden Block containing a Super Mushroom.
In Section 5, the player needs to get the Key from the other side of the Magikoopas and go to the top of the Warp Pipe. The Magikoopas do not move due to being on a Muncher. There is also a ? Block near the Key Door which contains a Super Mushroom on a Propeller Mushroom. To get to the next section without using the Key Door, the player needs to direct the Magikoopas' magic at Brick Blocks near the Key.
In Section 6, the player needs to get past Cheep Cheeps. The Key is conveniently near the Key Door. To get to the next section without the Key Door, the player needs to lure a Cheep Cheep to a Junior Clown Car, which comes out through One-Way Walls, and take it up.
In Section 7 after going down a Vine, the player needs to get past a Burner and endless number of Winged Bob-ombs due to one being in a Pipe. The player can also get Yoshi from a Yoshi Egg here. Beyond the Key are Hard Blocks, which can be destroyed by a Bob-omb's explosion. After a short climb on bridges, the player ends up in the last section.
In Section 8, the player needs to get the Key from Hammer Bros. and reach the Key Door at the end. However, if the player uses Yoshi's tongue to eat the hammers, then they can take out Big Wigglers and go to the Warp Pipe without needing to go through the Key Door.
