Water Land (alternatively Ocean Side, the Island World, Sea World, or Sea Side) is a water-themed world, and the third world in Super Mario Bros. 3. Water Land has nine stages, two Hammer Bros., two fortresses, five Toad Houses, five Spade Panels, and a castle. Cheep Cheeps and Bloopers are common enemies in this world, and the hard-to-dodge Boss Bass also lives here. This is the first world in Super Mario Bros. 3 to have more than one fortress.
The ruler of the swift tides of Water Land is Wendy O. Koopa. The real king of the land (who bears a resemblance to Mario and Luigi) resides in a castle on an island chain. The chain of islands is in the shape of Japan, with the castle being located where the city of Kyoto would be, the city in which the Nintendo headquarters is located. During the events of the game, the Water Land king is turned into a kappa; the SNES and Game Boy Advance versions of Super Mario Bros. 3 see him transformed as a Dino Rhino.
If the player has a Hammer in their inventory, they can break a rock to gain access to the canoe. The player can then control the canoe across the water to an island with two Toad Houses and two Spade Panels and a second island with a third Toad House.
It is possible to do a glitch in the Japanese version of the game; to perform, the player must stay on the canoe and get a Warp Whistle. It will result in walking on water, and getting into a glitched map. It can also be used to gain access to all the other worlds.
