Sparkling Waters

Sparkling Waters is the tropical third world of New Super Mario Bros. U and New Super Luigi 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 an archipelago with bubbling Water Spouts, which is quite similar to World 3 from New Super Mario Bros. 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 Koopa Jr. 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. There is a Balloon Baby Yoshi between Above the Cheep Cheep Seas and Urchin Shoals. The boss of this world is Larry Koopa. One color of each Toad House can be found here, along with the Secret Island, seen just left of Sparkling Waters.
