World 7 (New Super Mario Bros. Wii)

The Cloud Castle Courtyard is the 7th world in the game New Super Mario Bros. Wii. It is one the more difficult worlds in the game. Like the name implies, the area takes place in the clouds and sky. However, it does contain several enemies in its stages and is often abundant in items (mostly Ice Flowers, Fire Flowers and Propeller Mushrooms). Ludwig von Koopa himself is the boss of the world, and the player will see him on the roof of a fort he built with traps. The Enemy Course in this area contains a single Lakitu that throws Spinies.

7-2
This area features bubbles that Mario can swim in. It is also the only area to feature normal Chain Chomps. Other obstacles include Bullet Bills.

7-3
There are Fuzzies and Mega Fuzzies on this level. They can be quite a nuisance, especially when in swarms.

7-Fortress
The first part of this level contains a large platform similar to the one first seen in World 1-2. It can be controlled by tilting the Wii Remote left or right as it travels upward. The player is given an Ice Flower during this part of the level. Bullet Bills shoot from cannons on the sides of the level and run into each other in the middle of the screen and as the player gets closer to the top of the first part of the level, Banzai Bills will be shot from the right side. The second part of the level has the same platform with Bob-ombs replacing Bullet Bills.

Ludwig Von Koopa will shoot a magic fireball out of his wand and jump and do a flutter that's similar to Yoshi's flutter jump. In the second part of the stage, there is a secret exit from one of the walls on the right side. This leads to World 7-6.

7-Ghost House
This Ghost House introduces Broozers. Crowbers also appear near the end of the level.

Enemy Course

 * A Lakitu

7-6
This level can only be accessed after the player finds the secret exit in 7-Fortress. In this level, there are Para-Beetles and Heavy Parabeetles. Because there may not be any ground for the player, he/she will have to ride on the Para-Beetles to advance.

7-Castle
In this level, there are numerous spiked pillars that the player will have to avoid. They all vary in size. Sledge Bros. also make an appearance here.

Ludwig Von Koopa is fought again here. However, the fight takes place on three moving platforms.
