World 4 (New Super Mario Bros. Wii)

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.
