Water Land

This article is about the world from Super Mario Bros. 3. For the fourth world of Super Mario RPG: Legend of the Seven Stars, see Seaside. For the similarly named galaxy in Super Mario Galaxy, see Sea Slide Galaxy. For the similarly named kingdom in Super Mario Odyssey, see Seaside Kingdom.

Template:Location-infobox 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.

The map of Super Mario Advance 4: Super Mario Bros. 3 shows that it is located to the south of Desert Land, and west of Giant Land.

World 3-	File:SMAS 3-HB.png	Two Hammer Brothers patrol the map. Running into either one will result in a battle with two Hammer Brothers with two rows of seven breakable blocks each. The arena differs depending on where they are fought on the map. If encountered on land, they will be fought in an area with a hill to the left as well as a row of bushes extending to the right. If encountered in the water, the floor will be submerged. Defeating one of the Hammer Brother pairs will award the player with a chest containing a Hammer, while the other will yield a Starman. If the player met the unlock conditions for the Treasure Ship, one of the Hammer Brothers will be replaced with the ship.

Canoe

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 the glitch in the Japanese version of the game; to do that, 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 gain access to all the other worlds.

The Adventures of Super Mario Bros. 3

Water Land was only mentioned in one episode of The Adventures of Super Mario Bros. 3.

Sneaky Lying Cheating Giant Ninja Koopas: Bully (though speaking through Kooky's mouth due to an animation error) suggested that they could take over Water Land after having conquered Giant Land.

Nintendo Comics System

Water Land is the setting of the Nintendo Comics System story Fins and Roses, which has a heavily armed Wendy O. Koopa set up an ambush for Mario, only to be annoyed by Stanley the Talking Fish while waiting for the plumber's arrival.

Nintendo Adventure Books

In Leaping Lizards, Morton and Iggy Koopa have both set up bases in Water Land, a filthy houseboat and an underground laboratory, respectively. After the Mushroom King is transformed into a rabbit by Morton and no one can figure out how to change him back, Luigi and Toad head to Water Land to find Morton and get answers, with some of the creatures they encounter being Cheep Cheeps, Bloopers and Jelectros.

Trivia

• The music that plays in this land is very similar to the Fairy Fountain theme from The Legend of Zelda series.
• The Nintendo Power strategy guide for Super Mario Advance 4: Super Mario Bros. 3 erroneously labels this world as "Big Island" when describing the boss.
