The level begins with stone blocks that constantly move back and forth, which can crush the player. Two [[? Block]]s are found in between the platforms, one of which contains a power-up. Using a [[Mini Mushroom]], the player can climb up a wall that leads to a hidden area with [[coin]]s. [[Lava Bubble]]s are found jumping out of pits of [[lava]], and are followed by platforms with [[Dry Bones]] on them and moving blocks in the lava below. A [[Big Dry Bones]] is found, prior to a section in which the player passes through multiple moving blocks in order to continue. A hole in the ceiling can be once again accessed by using [[Mini Mario (form)|Mini Mario]], and leads to an area with multiple coins and a [[Brick Block]] containing a [[1-Up Mushroom]]. The [[Checkpoint Flag]] is found, with a Dry Bones and a ? Block containing a power-up nearby. A section of moving blocks above the lava must then be crossed. A [[Green Ring]] and a Dry Bones are on a platform above a moving block. The Mini Mushroom can be used once again to access a [[Pipe Cannon]] that catapults the player into another hidden area of gold coins. A passage containing a large amount of Lava Bubbles follows. The player must then cross the lava with moving blocks, with coins indicating sections in which there are openings. The boss door is then found at the end of the area.

During the boss battle with [[Morton Koopa Jr.]], he ground pounds the ground, causing a shockwave that can stun the player and causes a [[Big Pokey]] to appear. Morton uses his magic hammer to then knock [[Big Pokey]] segments at the player. After he is jumped on three times, he is defeated.

*'''Star Coin 1''': The player must run across the gap when the blocks are in the right position and grab the Star Coin.

*'''Star Coin 2''': The player must [[Wall Jump]] between the red [[Warp Pipe]] and the wall next to it to reach the area with the second Star Coin.

*'''Star Coin 3''': After the [[Checkpoint Flag]], the player must carefully maneuver on the blocks to reach the third Star Coin.
