Peach's Castle (world)

Peach's Castle is the final area of the main game in New Super Mario Bros. U and New Super Luigi U. It seems to be in the same place as it was in New Super Mario Bros. Wii. However, this iteration has a large moat surrounding the castle (as in Super Mario 64 and other games), an extra floor, as well as two extra towers on either side of the central tower.

In the game's opening, Bowser and his Koopalings once again attempt to kidnap Princess Peach. Bowser throws Mario, Luigi, Yellow and Blue Toad all the way to an Acorn Tree in the Acorn Plains. Afterwards, Bowser sends the Koopalings to secure the land's castles, while Bowser's Airship hovers over Princess Peach's. Over time, Bowser raids and remakes Peach's Castle into his own image, until it is eventually shrouded by a tornado created by Kamek.

Like its predecessors, the castle appears in the first level, Acorn Plains Way. However, unlike its predecessors, it's not seen at the start of the stage, as the Acorn Tree takes that spot. Instead, it appears near the end of the stage and even then, it appears very far into the distance. It's also the final, lava-themed world of New Super Mario Bros. U and New Super Luigi U, as at that point, the castle has been fully remade to Bowser's interest. The castle itself remains unchanged from the outside (it has changed on the inside, though), but the ground is charred and is surrounded by a moat of lava. There are six levels, making it the world with the least amount of levels in the game.

At the end of the game, Peach's Castle is restored to its original state. However, if the players play post-endgame, and enter the world, the area will revert back to how it was inside the tornado, except for the flags, as the black Bowser flags are still replaced by the white and pink Peach flags afterwards.

 * The world's theme is a devious-sounding remixed version of Super Mario 64's castle theme.
 * This is the first (and only) world from New Super Mario Bros. U and New Super Luigi U without any Toad Houses.
