Sparkle Ocean is the fourth world of New Super Mario Bros. Wii. If is on several tropical islands therefore, most of it's levels are water themed and have a rather good use on the Penguin Suit, which can glide over water and allow Mario to swim better. Also, on the map is a bridge surrounded by a giant Cheep-Cheep that can jump up and make Mario and the gang endure an Enemy Course. This is also the first world to have a level on an Airship, like there was in Super Mario Bros. 3.
