Sparkling Waters

Sparkling Waters is the tropical world in New Super Mario Bros. U. Players can reach it by moving south from the end of Layer Cake Desert, or via secret exit in Soda Jungle. Sparkling Waters lies east of Acorn Plains, south-east from Layer Cake Desert, south from Frosted Glacier, and west from Soda Jungle. Sparkling Waters is in an ocean filled with multiple islands and having bubbling water geysers, which is quite similar to World 4 from New Super Mario Bros Wii as that tropical world also had multiple islands. There are 7 levels in this world, consisting of 5 normal levels, the Fortress level and the Castle level. The boss of this world is Larry Koopa.
