Editing Castle

In ''[[Super Mario Bros.]]'', all castles are made of red bricks (except for the one in [[World 6-3 (Super Mario Bros.)|World 6-3]], which is gray), and all have the same basic shape. The castles can be found at the end of each world, but can also be found at the start of most worlds, aside from World 1, the first level of the game, and World 5, which starts with a [[fortress]] instead of a castle. Inside the first seven castles, the player will have to pass [[Fire Bar]]s, [[lava]] and other assorted dangers in a grey brick interior, leading up to an encounter with a [[Impostor Bowser|fake Bowser]]; defeating the impostor will allow [[Mario]] or [[Luigi]] to free a [[Toad (species)|mushroom retainer]], who informs them that their princess is in another castle. Only in World 8's castle do Mario or Luigi confront the real [[Bowser]] himself. Defeating him allows the plumbers to finally rescue [[Princess Peach|Princess Toadstool]]. Smaller castle-like fortresses also appear at the end of every level (except for the fourth level of each of world, where a normal castle appears) and the beginning of each water or underground level, where Mario emerges from and enters a [[Warp Pipe]]. Castles appear to be a fortress stacked upon a larger section.

Castles in ''[[New Super Mario Bros. Wii]]'' work in a similar way to how they acted in the [[New Super Mario Bros.|previous game]]. Mario and his allies traverse a dangerous, usually lava-filled area before having a rematch with one of the Koopalings; before the battle begins, [[Kamek|Magikoopa]] appears and uses his magic to alter the battle in ways to make Mario's battle more difficult, such as increasing the size of [[Lemmy|Lemmy Koopa]]'s ball or flooding [[Wendy|Wendy O. Koopa]]'s boss room. The final castle pits Mario and co. against Bowser, who is fought similarly to the original Super Mario Bros. Upon his defeat, Magikoopa appears again and uses his magic to turn Bowser giant, forcing the heroes to flee from the revived Koopa king for the rest of the stage.

Castles also appear in ''[[Super Mario 3D Land]]''. They once again serve as locations where bosses are fought, but unlike prior games are only found in four of the main eight worlds; one each in Worlds 1 and World 5, and two in World 8. The first two castles in the game are home to two [[Tail Bowser]]s, while both in World 8 are Bowser's castles, and pit Mario against the Koopa King himself. In the Special Worlds, castles appear more prominently; however, the majority of them are time trials, giving the player 30 seconds to complete. [[Dry Bowser]] resides inside the [[Special 1]], [[Special 5]], and [[Special 8]] castles. Also unlike prior games, all the castles in this game have a giant [[Goal Pole]] at the end.

Castles, along with [[Tower]]s, return in ''[[New Super Mario Bros. 2]]'', acting much like it did in the previous games. The [[Koopalings]] appear as the bosses only in the castles, as the Towers are occupied by [[Reznor]]s. A [[Hidden Block]] containing a [[Super Leaf]] can be found at the end of every castle before a Koopaling battle, with the exception of [[Lemmy|Lemmy Koopa]]'s castle, which has a [[Fire Flower]] in a Hidden Block at the end.
