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, an extra floor, as well as a tower on the right of the castle.

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 remakes Peach's Castle into his own image, until it is eventually shrouded by a tornado created by Kamek.

Like its predecessors, the castle can be seen in the first level, Acorn Plains Way. However, unlike its predecessors, it doesn't appear 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. It is notable that this world's theme is a remixed version of Super Mario 64's castle theme.

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.
