This level is similar to 8-Bowser's Castle in New Super Mario Bros. Wii On the First Section of the level, there will be rocket engines on the rope moving near the lava. Then Podoboos and Dry Bones walking near the stage. The Rocket Engines will starting turning on and off near the middle of the first section. Near the stages going up, on the very right, there will be a brick block which will turn into a Gold Block On the Second Section, Mario/Luigi must ride on the Snake Block. Before the Blocks pass the platform with the Star Coin, the Plumber/Plumbers must jump down to the platform to reach the Star Coin. Then the Plumbers must avoid the Rocket Engines while the Snake Blocks reach the platform on the door that leads to the Third Section. Once the plumbers enter the Third Section, one of the plumbers must pass the checkpoint in order to start there after the plumbers die. As the plumbers continuing running through the room, the Koopalings will ride on Bowser's Koopa Clown Car and try to blast the Plumbers. In order for the Plumbers to dodge, they must go behind the wall although the platforms are moving. If one of the plumbers is shot, they will lose a power. Near the middle of the section, there will be sets of donuts. On the first set in the middle row, the player must ride down the donut to get the coin. After getting the coin, the player must jump on another donut or the platform in order to stay alive. Then the player will enter the room to the Final Battle. The Final Battle and the gate are the same in 8-Bowser's Castle in the previous game, New Super Mario Bros. Wii. Instead, the player gets a checkpoint right after the gate and gets 3 Item Blocks containing at least 2 different power ups. After the player gets or ignores, they must go up the steps and dodge the fireballs that Bowser blows and finally battle Bowser. Like most of the previous games, Mario must get pass Bowser and press the switch to knock into the lava. Like New Super Mario Bros. Wii, instead of Kamek sprinkling Bowser and getting knocked out. The Koopalings sprinkle their father and get knocked out when he is enormous. Instead of going to the right to rescue Peach, this time the plumbers must go up the platforms before the lava reaches. Bowser will smash the platforms and when the plumbers reaches the top and turn on the switch. The lava then moves away making Bowser fall out of the Castle and Peach rescued. Later on, the Koopalings put Bowser into the Koopa Clown Car but fail once Bowser fits and the Koopalings do not so they are knocked down to a tree.
