Paper Mario: The Origami King

Paper Mario: The Origami King is the sixth installment in the Paper Mario series, released on the Nintendo Switch worldwide on July 17, 2020. The game follows the aesthetic style of its predecessor; Paper Mario: Color Splash, and follows Mario opposing an evil army of origami characters known as Folded Soldiers, ruled by the Origami King; King Olly, which have taken over the Mushroom Kingdom.

Prologue
The game begins with Mario and Luigi driving into Toad Town on the latter's kart, looking forward to the Origami Festival that Princess Peach has invited them to. Upon arrival, the brothers notice that the town is deserted, but continue on anyway, assuming that they arrived early. Luigi pulls up at the suspiciously empty Peach's Castle, and once he and Mario are inside, the doors lock behind them. While Luigi runs off to search for a key, Mario heads into the foyer, where he meets Peach, who has been folded into origami. Peach asks Mario if he wants to see the kingdom fold, and if he will fold himself as well, but regardless of his answers, she dismisses him by dropping him into a hidden dungeon beneath the floor, which several minions have already ended up there. There, Mario hears a noise, and by landing on a Magic Circle, he initiates the 1,000-Fold Arms for the first time, using them to peel the wall to reveal a trapped Olivia. Afterward, the duo go to a dungeon area and free a folded Bowser attached to a clothespin.

Escaping the dungeon to the upper outskirts of Peach's Castle from a secret passageway, Mario, after refusing to accept a Yellow Shy Guy's request to fold again, is ambushed by a group of Origami Goombas and Shy Guys. After defeating them, the Yellow Shy Guy next to Origami Peach reveals himself as Olivia's older brother, King Olly. He initiates the takeover of Peach's Castle by pulling the five streamers elsewhere in Mushroom Kingdom, wrapping the castle enough to have it separated from the ground. Mario, Olivia, and Bowser successfully escape via Koopa Clown Car, piloted by a Red Shy Guy. In addition to noticing Luigi's hat falling from the castle, the three on the car make a desperate attempt to reach the floating castle, but are approached by streamers. The red one inadvertently hits the car, sending the three flying out in the sky, as the Red Shy Guy rescues Bowser and heads off elsewhere.

Red streamer
Mario frees himself from a tree in a forest far from Toad Town, and after rescuing Olivia, they quickly notice that Peach's Castle has been relocated to the mountains. Both of them set out to destroy the five streamers, find Luigi, and defeat Olly. Their search begins with a trek through the Whispering Woods, where they are trapped by an angry old tree who has recently been cut down. Olivia convinces him that they mean no harm, and he tasks the two with finding a way to restore him to his former glory. Mario manages to find a Soul Seed in order to do so, and is allowed to leave the forest. Following that ordeal and the rescue of some folded-up Toads and Goombas, Mario and Olivia arrive in the ravaged and deserted Toad Town, where they encounter Paper Macho Goombas for the first time. Upon defeating them, they decide to search the remains of the castle for clues, needing to travel through the sewers in order to do so. The duo manages to find Luigi trapped within a wall, who quickly sets out to assist Mario by hunting down the castle's key.

Deciding to follow the red streamer first, they travel to Picnic Road, where they find a group of panicked Koopa Troopas who worship the Earth Vellumental. The door to his temple has been locked, and four of the five orbs required to open it have all been stolen by Folded Soldiers. Mario explores Overlook Mountain to find them, before accessing a deeper portion of the temple that has seemingly gone unnoticed. After navigating past a series of moving pillars and flames, Mario comes across the turtle-like god, who has also been turned into origami, and has no choice but to fight him; he manages to defeat him by making him tuck into his shell and attacking his stomach. Afterwards, Olivia gains the ability to transform into the Vellumental and uses her new power to access Overlook Tower. Upon arrival, the two have no choice but to use the stairs due to the elevator being broken, having to fill in some massive holes and help some Toads out along the way. At the top, the duo confronts the Colored Pencils, who is responsible for damaging the elevator, and they manage to thwart him by using his missiles against him. Following this, the red streamer is finally destroyed.

Blue streamer
With the red streamer gone, Mario and Olivia are now able to access the tram station, which can take them to Autumn Mountain, where the blue streamer seemingly is. On the way, they meet Bob-omb, an amnesiac, happy-go-lucky Bob-omb, who Olivia decides to call Bobby. They decide to let him tag along, and after a series of mishaps, they find the Water Vellumental Shrine. Defeating the corrupted dragon-like being allows Olivia to tap into its power, refilling the dried up river and allowing the crew to keep following the streamer. After finding a gondola driver, who has been folded into a monkey, they are finally able to set off, traveling through Eddy River and arriving at Shogun Studios.

Entering the park, the trio sees that it has been overrun with Folded Soldiers, and are tasked with fixing the place back up. Mario sets out to look for the staff key, which will allow him to access every part of the area; he ends up completing a trading sequence, eventually discovering the Ninja Attraction and entering it. Inside, he finds and rescues Luigi, who is convinced that he managed to find the key to the castle, but it turns out to actually be the staff key. Undeterred, Luigi sets off to try again, as Mario reopens the park and eventually gains access to Big Sho' Theater. After watching and starring in four different plays, Mario and the gang are confronted by the Rubber Band, whom they defeat by yanking his hair and flinging parts of his body out of reach. Now with the theme park saved, the gang celebrates their victory with some fireworks, which manage to reawaken Bob-omb's memories, and sets off to continue their quest.

Yellow streamer
Destroying the blue streamer allows the trio to continue down the river to Sweetpaper Valley, where King Olly shows up to confront them. He roadblocks them with a giant boulder, which also manages to squash Olivia. Bob-omb insists that they hurry to The Great Sea, with the help of Sea Captain Toad, whom they rescued back on Autumn Mountain to free Olivia. They stumble across an ocean-liner called The Princess Peach, a place he is extremely familiar with. After restoring the ship's power and rescuing the crew, they manage to find Bob-omb's old suite, where the very item he's looking for is trapped within a lock-box. Before they can open it, Gooper Blooper arrives and snatches it away, forcing Mario to fight him by hammering his weak points. Heading back to the valley, Bob-omb discloses his tragic backstory, involving the loss of his friends, his fuse, and his memories at the hands of Gooper Blooper. He then reveals that the object he wanted to find was his friend's fuse, which he lights up in order to sacrifice his own life, blowing up the boulder and saving Olivia in the process. Olivia is disheartened by this and runs off into the Breezy Tunnel, unsure if she is able to continue with the quest. Mario manages to cheer her up by finding Bob-omb's ghost and putting on a Goomba mask.

The two are given a Boot Car, which allows them to travel at high speeds, before heading out into the "Scorching" Sandpaper Desert. They find a series of odd temples and altars, but are unsure what they mean, so they decide to head into Snif City, a town completely run by Snifits, in order to find answers. At the hotel, they learn that one of the notable guests is Professor Toad, a wise explorer who is currently pursuing the legend of Captain T. Ode. They find him back out in the desert, having been eaten by a Paper Macho Mega Pokey, whom they promptly defeat. After the professor decides to tag along, they head back to the hotel, using the murals as clues to solve the ruins' puzzle. After awakening the Fire Vellumental Cave and defeating its phoenix-like occupant, Olivia is able to use her new abilities to light up some torches and unlock the Temple of Shrooms.

Deep inside, the gang discovers many Toads who have been kidnapped and defaced by the Hole Puncher, resulting in a zombie-like demeanor. They find a DJ who is being held hostage against his will, and must hunt down some discs in order to appease the Hole Puncher, while also rounding up all 40 Toads within the temple in order to make them dance. The Hole Puncher finally shows himself and fights Mario, who manages to kill him by attacking his bottom half. His defeat results in all the Toads having their faces restored, prompting them to head out and repopulate the now-renamed Shroom City. It is also revealed that the desert's sun was trapped inside the disco ball, this explaining the permanent nighttime aesthetic. The sun being out also allows the gang to open the Sun Altar, where they find Captain T. Ode, an ancient sea captain, preserved in a block of ice. Olivia frees him with her new fire powers, prompting him to scurry off in search of his old submarine, the Super Marino. Once Mario and Olivia decide to continue on in their quest, Professor Toad decides to stay behind, feeling that he is most at home in the desert.

Purple streamer
Mario and Olivia decide to explore the Great Sea properly, but find that certain parts of the map are hidden due to a thick fog. With no choice but to head back, the two find Captain T. Ode at the Museé Champignon, where his old submarine is being kept as an exhibit. The museum owner reluctantly lets them take it, attaching it to the back of Sea Captain Toad's ship and granting them the ability to salvage underwater treasures. Navigating the fog with the help of the ancient captain's Sea Chart, the gang comes across Bonehead Island, and solving a puzzle they find there clears the fog and opens up the entire ocean. The gang soon discovers the Sea Tower at the northernmost portion of the map, where the purple streamer seems to end, but finds that they cannot access it without finding three orbs located on Diamond Island.

While searching for the island, Mario finds a chest on Full Moon Island, seemingly containing a key that leads to it, only to find a note from Luigi instead, saying he finally accomplished his goal. The Mario Bros. reunite again on Mushroom Island, where Luigi once again realizes that he found the wrong key. Nonetheless, he sticks around to help his brother explore their current surroundings, eventually following him into the basement and finding a room filled with harmless origami. Olivia frees the Origami Craftsman from within the wall, who expresses shock at how she is alive. He then explains that he originally created King Olly in order to simply be part of a display he was working on, but did so with the Forbidden Folds, which thus brought him to life. Olly turned on his creator and set out to fold the world in his image, also managing to create Olivia with the same spell (before the Craftsman got the chance to), who he wanted to share his authority with.

Now more determined to stop him than ever, the gang uses their newfound key (as Luigi once again leaves to find the right key) to access Diamond Island, which is completely submerged and can only be accessed via the Marino. Mario and Olivia discover several temples leading to trials of Power, Wisdom, and Courage, though the latter two cannot be accessed without the Ice Vellumental's powers, which they promptly gain by traversing the nearby Ice Vellumental Mountain. After gaining the fourth and final Vellumental power, the duo complete the trials, gaining an orb from each one and using them to unlock the Sea Tower. After a long climb, involving many callback to previous Vellumental temples, the duo confronts the Tape at the top, whom they defeat by destroying his holder and then unraveling him.

Green streamer
After one last puzzle involving all four Vellumental abilities, Mario and Olivia finally notice the green streamer, and see that it is heading into the clouds. A mysterious light appears on top of the Sea Tower, and stepping into it transports them all the way to Shangri-Spa, where it is revealed that Bowser's Castle had crash-landed into it, resulting in his uncorrupted minions being forced to clean the place up. Here, the duo meet Kamek, who is attempting to take back the castle, but can't due to Boss Sumo Bro. guarding its entrance. The only way to reach him is via Bowser Jr.'s Junior Clown Car; Jr. quickly arrives and attempts to attack the Sumo Bros., but is quickly shredded by the Scissors. Kamek reluctantly joins the gang and follows them to all four of the spa's hot springs (in almost any order the player chooses) so he can revive the young koopa. Though they ultimately succeed, Jr. ends up completely colorless.

Using the stamp card he was given earlier, Mario uses it to gain a VIP pass to the Spring of Rainbows, which he can only reach after navigating some windy cliffsides and playing through Shy Guys Finish Last. With Bowser Jr.'s color restored, he is able to fly the gang up to Boss Sumo Bro., whom is promptly defeated. With the castle now unguarded, Kamek rallies the remaining minions to fight, allowing he, Mario, and Olivia to search the castle. In order to find the key to the throne room, they must follow Kamek to his quarters, but he ends up mysteriously disappearing. On top of that, Luigi is revealed to have gotten there first, having found the very key they're looking for, and once again having no luck finding the one to Peach's Castle. Shortly after, Olivia is snatched up by Handaconda, who retreats to the Throne Room. Mario travels there alone, fighting through several mysterious cutout enemies, before finally confronting his partner's captor, whom he defeats by playing Rock Paper Scissors with the 1,000-Fold Arms.

Following this, the duo notices several of Bowser's minions having been cut up, before the Scissors arrive and challenge them to a fight. Before hand, though, he decides to toy with them by sending out the Paper Mistake Buzzy Beetle, who is quickly dispatched. Mario manages to defeat the Scissors by attacking his handle and freezing him solid, before whaling on him with the 1,000-Fold Arms. This causes the cut-up minions to be restored, as Mario and Olivia quickly destroy the fifth and final streamer.

Origami Castle
Following the restoration of his army, Bowser, who is once again freed from a clothespin, reveals that he has an idea on how to reach Peach's relocated castle, beckoning Mario and Olivia to follow him. This idea is shown to be a new, improved version of his Airship, where many of his paper minions, as well as Bowser Jr. and Kamek, decide to venture off to the transformed Peach's Castle with Mario and Olivia. However, they soon get attacked by a Paper Plane Squadron group, and although Mario defeats them all, one of the squadron planes crashes and damages Bowser's Airship, where it lands into Hotfoot Crater. Mario, Kamek and Bowser Jr. venture off to Bowser, while being attacked by a horde of Paper Macho Goombas. Kamek attempts to hold back the horde to no avail, sacrificing himself, while Bowser Jr. stomps on a loose rock in their path to create a ditch which the horde topples onto him in, which only leaves Mario and Olivia to reach Bowser, who use the Airship's cannon to launch to Peach's Castle.

They land outside of the Castle, but cannot get inside as the door is locked, but Luigi returns with his kart, who reveals that he has the final key. Once they enter inside, they are greeted by the Origami Peach. Luigi attempts to save her, but falls down the trap door. King Olly then transforms Peach's Castle into his own Origami Castle.

Gameplay
The overworld exploration is quite different from the series' standard; whereas the previous three games were either sorted into individual chapters or levels, The Origami King switches to a completely open-world style of progression, with Mario being able to travel to any of the game's locales completely on foot like the first two games. The game's combat system has also been overhauled: at the start of each turn, Mario can rotate and slide rings of a circular battle arena, lining up enemies for consecutive attacks, although the number of ring moves and allotted time are limited. Mario has permanent Boots and Hammer attacks, and may equip stronger variants that break after a while. Attacking enemies on the overworld will grant Mario an extra attack in battle, and timed button presses can increase damage when attacking. Lining up the enemies successfully will increase Mario's attack power by a factor of 1.5. Coins can be spent to extend the time limit (at a rate of 10 coins per second), or call the Toads that have been saved to assist Mario in battle. Boss battles use a different system in which the player rotates and slides the rings to line up arrows, making a path for Mario to attack. In a similar vein to the two previous installments, this game has no experience points or level up mechanics, and coins are the only reward.

Olivia, a character new to the franchise, has a role similar to Kersti and Huey from Paper Mario: Sticker Star and Paper Mario: Color Splash respectively. Once a Vellumental is defeated, Olivia can transform into the Vellumental while standing on Magic Circles, an ability that carries over into battle. Additionally, partners return to ally with Mario and aid him in battles, including Bob-omb and Kamek. Various partners join and leave Mario's party at various points in the story.

Accessories (which seem to function similarly to Badges from the first two games) grant Mario benefits both in battle and on the overworld. Toads can be found on the overworld, folded into various shapes. Hitting these Toads with the hammer will cause them to unfold and return to Toad Town, some of which open shops. The Toads that have been saved can even help in battle if the player spends coins using the Cheer command. These Toads will fight enemies, heal Mario, give items, and solve puzzles. Mario can gain confetti by using his Hammer on trees, grass, and enemies. This confetti can be used to fill Not-Bottomless Holes torn in the landscape, revealing Coins or a Toad.

Nintendo eShop description
 The kingdom has been ravaged by an origami menace! Join Mario and his new partner, Olivia, as they battle evil Folded Soldiers, repair the damaged landscape, and try to free Princess Peach's castle from the clutches of King Olly in this comedy-filled adventure, only on the Nintendo Switch system.

Mario and Luigi receive an invitation from Princess Peach to attend an origami festival and excitedly hurry to Toad Town...but something's amiss. After investigating the eerily empty town, the duo finds a fearsome (and folded) Princess Peach-she's been turned into origami by King Olly, ruler of the Origami Kingdom! With five giant streamers under his control, King Olly binds Princess Peach's Castle and transports it to a distant mountain as part of his plan to re-fold the world.

On his journey to liberate Peach's Castle and repair the ravaged paper landscape, Mario meets Olivia, King Olly's sister, and the two join forces to put a stop to Olly's origami onslaught. Even Bowser falls victim to Olly's plot when his minions are turned into origami Folded Soldiers and betray their Koopa king, forcing him to ally with Mario and Olivia!

Battle the Folded Soldiers in ring-based battles the challenge you to strategically line up enemies to maximize damage! Out of battle, Mario can use the arm-extending 1,000-Fold Arms ability in specific spots to interact with the landscape to pull, peel, hit, and more! Join Mario, Olivia, and their companions on a journey of laughter and emotion, thrills, and a whole lot of folding.

The way Bowser Jr. restores his colors from it also resembles the paint mechanic in this game.
 * The Legend of Zelda: Breath of the Wild: A Toad that is trying to climb a cliff in the Autumn Mountain references the climbing mechanic where it is harder to climb when it is raining by saying, "But hey, at least it isn't raining."

Similarities to other Paper Mario games

 * Like the original game and its sequel, Mario and Luigi receive an invitation from Princess Peach.
 * Although Peach gives Mario a letter in Color Splash, said letter is actually a color-drained Toad.
 * In combat, Mario's basic jump and hammer attacks are permanent, like in the first two games.
 * Partners return from the first three games.
 * Just like in the second and third games, Bowser is not the primary villain. Rather, Mario and Bowser team up, as they do in Super Paper Mario.
 * Just like in Paper Mario: The Thousand-Year Door, Peach is turned evil by the main antagonist, similarly to the Shadow Queen.
 * Like the previous five games, there is a part that plays like a game show.
 * NPCs based on enemy species return from the first two games.
 * Mario can use confetti to fill in Non-Bottomless Holes, similarly to using paint to fill in colorless spots in Color Splash. Like paint, confetti is limited.
 * Like the previous two games, there is a performance starring Birdo.
 * Like the first game, Peach's Castle gets taken over by the main antagonist.
 * Like in the first four games, Mario fights a Blooper as a boss.
 * Like in Paper Mario: The Thousand-Year Door, battles take place in front of an audience, and the audience can interact with Mario.
 * However, the audience only consists of Toads, the number of audience members depends on the rescued Toads, they need to be paid in order to influence the battle, and they do not attack Mario for a bad "performance".
 * Like in the previous three games, Mario has a permanent travelling companion who can float, in this case, Olivia.
 * Like in Super Paper Mario, the main antagonist has taken control of some of Bowser's minions.
 * Shiny and Flashy variants of attacks return from Paper Mario: Sticker Star.
 * Princess Peach is depicted in artwork without her lipstick, much like in the first two games.

Differences from other Paper Mario games

 * This is the first game in the series in which Bowser is not fought in any way, shape, or form.
 * It is also the first Mario role-playing game overall in which Bowser is not fought.
 * This is the first game in the series where the overall objective does not involve finding any major collectibles (e.g. the Crystal Stars or Pure Hearts), rather to destroy giant streamers blocking Peach's Castle.
 * Save prompts now have a distinctive look, separate from normal textboxes.
 * When getting a Game Over, an option to restart from the last save (or in the case for minigames and the final boss, to try again) is now available.
 * When Mario gets hit by a First Strike, he can no longer block the attack.

Critical response
Paper Mario: The Origami King received positive reviews from critics, who praised the expansive overworld, graphics, writing, and plot, but criticized the battling system for being repetitive, frustrating, and unrewarding.

Wave battle glitch
If a wave battle is supposed to start, but only one enemy is alive and another is in their death animation, it will still initiate a wave battle and consider both enemies alive.

Sumo Bro glitch
During the second phase of the Boss Sumo Bro rematch in the Battle Lab, defeating the Boss Sumo Bro with a POW Block without defeating the two Sumo Bros beforehand will cause the game to softlock.

VIP pass glitch
In Shangri-Spa, after obtaining the VIP pass to access the Spring of Rainbows, if the player leaves the path to the Spring of Rainbows after entering, the VIP pass will be gone from the menu. If the player then speaks to the Toad at the reception, they will not have the stamp card and there is no way to get another one. Saving after this point will brick the save file.
