Layout
This tower is the first level to feature Fire Bars. The level begins at the bottom of the tower, above a pool of lava. The first Fire Bar is found next to two ? Blocks, one of which contains a power-up. Moving rock platforms that allow the player to progress are found, along with two more Fire Bars. Another Fire Bar is found along with a ? Block, where the player can climb up platforms on either the left or the right of a wall in the center. A double Fire Bar appears at the top of the section. On the right side, a Warp Door can be found in the wall, leading to a room with a Roulette Block. Above the door is a Hidden Block with a 1-Up Mushroom. Another section containing moving platforms and ? Blocks follows. The player then encounters a section of climbing semi-solid platforms while avoiding Fire Bars, along with a moving platform. A section with a large amount of moving platforms is found, with coins indicating where the player can stand without getting crushed. The midway point is then found, followed by another moving platform, along with a Fire Bar. A Brick Block containing a 1-Up Mushroom is next to the Fire Bar. A final Fire Bar is found, along with two moving platforms. The boss door is found at the top of the area, with two ? Blocks above moving platforms, one of which contains a power-up.

Magikoopa is fought at the end, where he uses his magic to make the battle room's platforms move to the left. Magikoopa teleports often while the platforms move. His magic transforms one platform into one or more enemies. Enemies can vary between Koopa Troopas, Koopa Paratroopas, Goombas, Bob-ombs, Monty Moles, Thwomps, Buzzy Beetles, and Spinies. An occasional Super Mushroom may also pop up, as well as Coins.

Star Coins

 * Star Coin 1: The first Star Coin is near the beginning of the level, atop a Fire Bar.
 * Star Coin 2: Directly below the midway point is a hidden area with a door that can only be accessed by the moving platforms immediately below. Once inside, Mario and co. have to avoid the fast Fire Bars, make it to the highest platform, then jump up to get the second Star Coin.
 * Star Coin 3: The third Star Coin is to the immediate left of the midway point, under a platform with a Fire Bar. Mario and co. must duck-slide through the gap (unless not Super) while avoiding the Fire Bar to get it.
