Paper Macho Koopa Troopas
- “Mario, since I know best, I have refolded this castle in my image. I sincerely hope you enjoy it.”
- —King Olly, Paper Mario: The Origami King
Origami Castle is a location in Paper Mario: The Origami King, the final area to be visited in the game. It is a corrupted version of Peach's Castle crafted and ruled by King Olly, who is fought at the end in addition to Stapler. Almost everything here is made of origami, including the Warp Pipes and ? Blocks. There are no Toads or Not-Bottomless Holes to be found here.
When Mario, Olivia, Bowser and Luigi enter Peach's Castle, Princess Peach appears and asks that they follow her. Luigi runs toward her and ends up falling into the same trap door Mario fell into at the beginning of the game. Mario, Olivia and Bowser must follow Princess Peach into the next hallway, where she tells them it is an honor to meet King Olly before the floor retracts, creating a set of stairs pushing them out of the castle. The castle then begins to unravel and fold into cubes, assembling into a large-scale version of the model found in the Origami Craftsman's workshop. Mario, Olivia and Bowser can only enter the castle and hope to rescue Luigi and Princess Peach.
Before they can enter the castle, Mario must use his hammer to flip over two tiles, revealing a Magic Circle allowing him to use the 1,000-Fold Arms to pull down and open the main doors. However, they are then immediately attacked by two Fire Bros. When they enter the castle, they are spotted by two Folded Soldiers, a Goomba and a Koopa Troopa. They rush to a nearby King Olly and inform him of their arrival. However, Olly becomes annoyed they were not able to stop them and feeds them to the hungry floor, which resembles paper fortune tellers. He welcomes Mario into the castle and is interrupted by Olivia, who tells him he has gone too far. He shrugs this off and leaves them to deal with a number of enemies and obstacles.
When Mario, Olivia and Bowser enter the main hall, they are stopped again by Olly, who slows them down by redirecting the path leading directly to the north end, leading it instead into the rooms left and right of the main hall. Mario must make it through these rooms, fix the path, and make it to the north end. He must then solve the sliding block puzzle to advance to the next rooms.
In the following room, Mario is ambushed by an army of Folded Soldiers, although they can be quickly and easily dealt with thanks to the wobbly statue of King Olly nearby. In the room after this, Mario again encounters Olly, who mentions he is wrapping up his final plot. Not able to recruit them, he sics Stapler on them. Mario is able to defeat it, although this soon proves much to Olivia, stunned that her own brother tried to kill her. She sits down on a bench in the next room, wondering if they are powerful enough to stop him. Bowser reassures her by reminding Olivia of everything he has gone through. This cheers Olivia up, prompting her to thank everyone who has helped them along the way.
Mario finally enters Olly's throne room, where he is residing in his throne next to a throne presumably meant for Olivia. Here, he shows them the image of Princess Peach, who has become a part of the castle. Olivia also notices the numerous paper cranes in the room. He reveals his plan to create 1,000 paper cranes, granting him a wish he plans to use to turn the Toads into blank paper. Even Bowser is against this, as the effects would be permanent. Olivia reminds Olly he was created by the Origami Craftsman, which Olly cites as his reason for all of this. Finally, he tells Mario he plans to use him as the thousandth crane, initiating the final battle.
With Olly defeated once and for all, he becomes too weak to do much of anything. Having finally come to his senses, he sees the error of his ways. Olivia notices a message on his stomach, revealing the Origami Craftsman's true intentions for him, for his fate to be of a fair and kind king. This amuses Olly, who then apologizes to the others for everything he has done. In his dying breaths, he requests Olivia to fold him into the thousandth crane, allowing her to grant a wish of her own. She uses this wish to undo all of the origami done by Olly, thus turning Origami Castle back into Peach's Castle.
Outside of the castle, there is a Save Block, two ? Blocks, and the sixth and final long-distance Warp Pipe. In the first floor of the castle, there are four ? Blocks, a few Fire Bros, and a Sumo Bro summoned by Olly. The second floor serves as the main hall, with a bridge leading to a block puzzle on the north end; King Olly refolds the bridge to redirect to rooms to the right and left. Both of these rooms are smaller and simpler. To solve the block puzzle on the end of the main hall, Mario must activate a Magic Circle and use the 1,000-Fold Arms to slam in certain blocks, creating a flat path to the doorway to the next area. In the third floor, Mario is ambushed by a number of Folded Soldiers. Fortunately, there is a wobbly statue of King Olly which can be knocked off its pedestal to flip the bridge, sending the unfortunate minions into the hungry floor. In the subsequent rooms, Mario fights Stapler and Olly himself.
