The castle's prominent features are Spiked Balls and Snake Blocks. The player begins under some Spiked Balls trapped in Snake Blocks, and two ? Blocks. After that is a small series of Spiked Balls and Snake Blocks, with another ? Block, a Brick Block and a Fire Bar. There are some openings above which will drop an infinite amount of Spiked Balls. A Dry Bones is also on one of the platforms. After that lies a Roulette Block, two Fire Bars and some sets of stairs. Then, there is a large platform with Snake Blocks that carry an infinite amount of Spiked Balls, as we as a Dry Bones and a Fire Bar. After that lies a Checkpoint Flag, another ? Block, and some Big Spiked Balls with a regular sized Spiked Ball, which are being moved by more Snake Blocks. After that, there is a set of ? Blocks, a platform with Snake Blocks and a Dry Bones, and a platform above that drops an infinite amount of Spiked Balls. After crossing that, there are Fire Bars and some sets of stairs, followed by red and green Warp Pipes. Finally, there are three Big Spiked Balls with Snake Blocks, and the boss door leading to Morton Koopa Jr.
=== Boss battle ===
In the battle, Morton jumps out of a large Warp Pipe, and uses his wand to cast Spiked Balls. He can also pound the ground which stuns Mario and Luigi if they are on the ground. The Bros. simply jump on him three times or fire 18 fireballs if they are Fire Mario or Fire Luigi. After each time he is hit, Morton spins off screen on the bottom ground, and re-appears via the large Warp Pipe on the ceiling, back on higher ground. After defeating him, the Bros. collect the keys to open the gate, where Princess Peach and Ludwig von Koopa await them. As they reach them, Ludwig taunts before running off with the princess, and the Bros. chase them to World 5.
