Iteration of	Bowser's Castle

Bowser's Castle appears in Mario & Luigi: Paper Jam located near Doop Doop Dunes. The castle can also be seen off in the distance at several points in the game. The castle also has a cannon built into the roof, which Bowser uses to destroy the bridge connecting his castle to Doop Doop Dunes as well as knock out Mario, Luigi and Paper Mario.

The castle is first seen during the first cutscene involving Bowser, where after a disagreement and then a brawl, he and his paper counterpart decide to team up. They proceed to kidnap their respective Princess Peaches and return to the castle. The castle is later seen in Doop Doop Dunes, where upon entering the area, the Mario Bros. and Paper Mario spot Bowser's Castle in the distance, which they must cross the desert to reach. As they come close, the Bowsers notice and decide to blast the gang with cannonballs. The first shot misses them, but destroys the bridge connecting the castle to the desert, while the second shot knocks them all out cold. Wendy, Roy, Larry and Ludwig then arrive to take them to the Twinsy Tropics Dungeon, while the Bowser Jr. duo collects the book containing Paper Mario's world.

Much later in the game, the group reaches Bowser's Castle in order to rescue the princesses and get the book back. They learn the Trio Glider before encountering the two Kameks and Papercraft King Boo, who is controlled by Morton and Lemmy. Toadette also arrives just in time with a Papercraft Yoshi to fight the Papercraft King Boo. After the victory, Kamek kidnaps Toadette to bring the production of papercrafts to a stop, then prepares to build Papercraft Bowser. The gang later rescues Toadette before encountering the Bowser Juniors on guard duty.

The Princess Peaches then escape and greet the team, but are caught by the Bowser Juniors. They mean to fight, but after accidentally revealing they possessed the book the Bros. are after (which they did not know they had), the pair flee. The group eventually catches them and forces them to hand over the book, but the Juniors escape after giving them a decoy book. The gang chases them down and engages in a battle with them, defeating the pair. Before they can get the book back, the two Bowsers enter the room, enraged at their sons' defeat. They then activate "the boosters", lifting Bowser's Castle out of the lava moat and dubbing it "Neo Bowser Castle". The gang escapes, forgetting the book, and the Bowsers retaliate for their sons' defeat by firing on Peach's Castle and ravaging it. The castle is presumably returned to ground level after the Bowsers' defeat.

Unlike other Mario & Luigi games, the castle's design is based on its designs from New Super Mario Bros. Wii and New Super Mario Bros. 2 and lacks the Bowser head and "arm towers" of the previous designs. Additionally, Bowser's Castle is located at the edge of a desert instead of a volcanic wasteland, although a giant lava moat is built around the castle. Additionally, this design does not have a stone head of Bowser anywhere, but instead has a green Bowser-like emblem logo in the center. Further reflecting on the designs of contemporary main series incarnations, the castle sports a large number of spiked green domes that resemble Bowser's shell.

After Bowser's Castle becomes Neo Bowser Castle, its original location at the end of Doop Doop Dunes can no longer be explored, even when the game is completed.
