Editing World 8-Bowser's Castle (New Super Mario Bros. Wii)

For the first (out of two) rooms there are a lot of [[Lava Bubble]]s, which will jump out of the lava to attack the player. They can be stopped by an [[Ice Flower]], while the [[Fire Bar]]s that also appear need to be avoided. The second room has a lot of [[slow falling platform]]s and sinking lava, but the platforms fall faster than the lava. In the last room, there is a big green door leading the player to the final battle against [[Bowser]] himself. The player needs to make sure to reach the [[Checkpoint Flag|midway point]] first before Mario enters the final showdown against the Koopa King. On the far right of this room by the door to the final battle, there is a hidden block that contains a [[Super Mushroom|Mushroom]] or a [[Fire Flower]] that will help him in the final fight. Then, Mario enters the giant green doors leading to the final battle.

In the corridor after going through the doors, Bowser's fireballs will come from offscreen to the right. Once Mario reaches Bowser, the door closes. In the first phase of the final battle, Bowser will breathe fireballs at Mario. Mario must wait for Bowser to jump so he can go under Bowser and hit the switch. Bowser will fall, but the person in the cage that Mario was expecting to be Peach turns out to be [[Kamek|Magikoopa]] in disguise, unfortunately. Magikoopa will make Bowser grow, but to his astonishment, Bowser grows too much. [[Giant Bowser|Super Bowser]] spits fireballs at Mario and breaks the walls (or obstacles) while chasing them. He can also stomp to create hazardous lava waves. Mario will be forced to outrun Super Bowser's attacks. [[Propeller Mushroom]]s and [[Fire Flower]]s can help him in this chase. Eventually, after hopping on several floating platforms, Mario will see a giant orange switch at the end of the room with an exclamation mark on it with Peach in a cage above. Mario hits it, causing the lava to sink, along with Super Bowser. The final victory fanfare is heard and Peach falls down, and they go outside where they see Luigi and the Toads on their [[Hot Air Balloon]]s. Luigi lets them go and as he is about to enter, the balloon leaves him behind, so the Toads decided to let Luigi enter the other balloon. Then, Peach tells Mario about the [[World 9 (New Super Mario Bros. Wii)|secret world, World 9]], but if Mario beats the level again, Peach will ask Mario to tell her about his adventure again. After the cutscene, the credits, which are made of breakable [[Brick Block|brick]]s, begin.
