Sparkling Waters

Sparkling Waters is the tropical third world of New Super Mario Bros. U. Players can reach it by moving south from the end of Layer Cake Desert. Sparkling Waters lies east of Acorn Plains, south-east from Layer-Cake Desert, south from Frosted Glacier, west from Soda Jungle and Rock-Candy Mines and south-west from Meringue Clouds and Peach's Castle. 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. It's one of two of the worlds that the player can choose from after beating Morton in Morton’s Compactor Castle, the other being Frosted Glacier. Because of this, it is quite possible to play through the game without ever reaching Sparkling Waters. The world's name is possibly a reference to carbonated water. There are 9 levels in this world, consisting of 5 normal levels, a Sunken Ship, a secret level, the Tower level and the Castle level. The boss of this world is Larry Koopa. One colour of each Toad House can be found here, along with the Secret Island, seen just left of Sparkling Waters.
