Meringue Clouds

Meringue Clouds is the sky world of New Super Mario Bros. U. It is east of Acorn Plains, Layer-Cake Desert, Sparkling Waters, and Frosted Glacier, northeast of Soda Jungle, northwest of Rock-Candy Mines, and south of Peach's Castle. It seems to be seperated from Rock-Candy Mines by a Bonecoaster track. It is a sky world similar to World 7 from New Super Mario Bros. Wii and World 5 from New Super Mario Bros. 2, but unlike those two worlds, there are two levels taking place at sunset and the Castle at night, which is marked off by different cloud colouration. It seems to take over a cliff next to World 1, the grass-themed world from the previous New Super Mario Bros. games, in between Rock-Candy Mines and Peach's Castle. Its name is derived from a French dessert made from whipped egg whites and sugar. There are 9 levels in this world, with 6 normal levels, one being is the third Ghost House in the game, the Tower level and the Castle level. The boss of this world is Ludwig von Koopa.
