If the player takes the path second from the bottom, they will first have to avoid a sliding Thwomp and ride a Donut Lift downward to other platforms they have to jump across, while avoiding a Roto-Disc. Afterward, they must jump across Donut Lift platforms while avoiding Bowser's Fire Breath, along with avoiding one more Bowser Statue above. If the player takes the top path, they will have to jump over four Bowser Statues. At the end of this area, the path splits in four ways, with the second from the top path having a power-up and the bottom-most path leading back to the start of the castle.

Next, the player has to jump across several Donut Lift platforms while avoiding Podoboos and falling in the lava below.

A 1-Up Mushroom can also be collected at the top of the stairs, next to the wall on the right. After passing a Hot Foot, the player will have to jump up stairs lined with three Roto-Discs, then fall down the next set of stairs avoiding the same Roto-Discs. Once the lift reaches its peak, the player will find a Donut Lift to the right and must ride it down, jumping off to the right when able before the block falls into the abyss.

At the top of a set of stairs is an invisible lift that will start rising when the player steps onto it if the player misses the lift, they can enter the nearby door and then move left, avoiding Dry Bones, to another door to be brought back to the beginning of the castle to try again. The player starts next to a trio of Bowser Statues, which will fire lasers when the player approaches.
