Meringue Clouds

Meringue Clouds is the cloudy seventh world of New Super Mario Bros. U, New Super Luigi U, and New Super Mario Bros. U Deluxe. 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 previous New Super Mario Bros. games, but unlike that world, Meringue Clouds takes place during sunset and Ludwig's Clockwork Castle taking place right in front of the tornado surrounding Peach's Castle, which is marked off by different cloud coloration. 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 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 just like how he is the boss of every cloud world from the previous New Super Mario Bros. games.

Super Smash Bros. series
Meringue Clouds appears in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate as one of the stage variations of the Mushroom Kingdom U stage, using the sunset setting found in two of its stages. The layout consists of a few platforms, including two that players can fall through. Several obstacles may appear in this section of the stage, including Stretch Blocks, water geysers that may carry Big Urchins, and a giant beanstalk that grows in the middle of the stage.
