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. The world can be either accessed by completing Roy's Conveyor Castle or completing Flight of the Para-Beetles, Soda Jungle's secret level.

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 taking place near the tornado surrounding Peach's Castle, 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 10 levels in this world, with 6 normal levels, one being is the third Ghost House in the game, the Tower level, the Castle level and the Airship level. The boss of this world is Ludwig von Koopa.
