Layer-Cake Desert

Layer-Cake Desert is the sandy second world of New Super Mario Bros. U, lying directly north of Acorn Plains, north-west of Sparkling Waters and Soda Jungle and south-west from Frosted Glacier. Unlike the previous desert worlds, which had Egyptian pyramids, it has various desserts within the world, such as giant cakes (with one giant cake in the world map) and giant melting ice cream cones. Part of the name is derived from a type of cake with multiple layers, held together by frosting. The second part is a reference to the similarities between "desert" and "dessert". The boss of this world is Morton Koopa Jr., who was also the boss of Desert Hill in Super Mario Bros. 3. There are also giant Moai statues in a sea of sand, which also appear in some levels and in the world map. A Super Acorn can also be found in the map alongside the Enemy Courses, where it'll place the Super Acorn in the inventory box. There are 9 levels in this world, with 6 normal levels, a secret level, the Tower level and the Castle level, as well as a Goomba and a Fire Bro. Enemy Course, two red Toad Houses and a green Toad House. At the end of Layer-Cake Desert, there's a fork in the road, allowing the player to progress either to Frosted Glacier or Sparkling Waters.
