Paper Mario: The Thousand-Year Door
Paper Mario: The Thousand-Year Door is the second installment in the Paper Mario series, with the first being Paper Mario. It was released for the Nintendo GameCube in 2004. Its plot revolves around Mario, who embarks on a mission to collect the seven Crystal Stars in order to open the Thousand-Year Door. After learning that Princess Peach has been kidnapped, he also sets out on a mission to rescue her from the X-Nauts. The game has intermissions between each chapter, in which the player assumes the role of Peach, as well as Bowser, who have their own stories that complement the main plot.
Prologue: A Rogue's Welcome
The adventure begins when Princess Peach goes on a cruise to Rogueport where she meets a hooded woman, and buys a box which contains a map. She sends this to Mario, along with a letter asking him to help her search for the map's treasure. Soon after that, she is kidnapped by Sir Grodus. Mario receives the letter with the map and decides to help her, and thus boards a ship to Rogueport.
Shortly after Mario reaches Rogueport, he finds Lord Crump attempting to interrogate Goombella about the Crystal Stars. Mario intervenes and Lord Crump tries to defeat him. After defeating the X-Naut general and escaping from the X-Nauts, Goombella introduces herself, and Mario explains his quest to her. As Goombella is also searching for the map's treasure, she decides to join Mario. Then, Goombella suggests to go to Professor Frankly's house, to consult him and show him the map. At the professor's house, Frankly explains that the map is related to the legend of the treasure of the Thousand-Year Door, and that, to obtain the treasure, one must first open the door with the seven Crystal Stars. Said objects can be found by holding the Magical Map before the Thousand-Year Door, which is located in the town's sewers. So, Mario holds the map before the Thousand-Year Door, revealing the location of the first Crystal Star.

Chapter 1: Castle and Dragon
Mario and Goombella show the updated map to Professor Frankly, who reveals that the first Crystal Star is in Petal Meadows. To reach this place, they must find a pipe in Rogueport Sewers. After finding it, Mario and Goombella arrive in Petal Meadows, where they see Hooktail and her castle. The duo stops at a nearby village called Petalburg and discover from the mayor that the dragon Hooktail has been terrorizing the village. The mayor tells them that Hooktail guards the Crystal Star in her castle, and that to access it, they must find the two stone keys in Shhwonk Fortress. After finding them, Mario and Goombella march to Hooktail's castle, with Koops in tow (who wants to defeat Hooktail to avenge his dead father and become stronger). After navigating through the castle's traps with the help of Koops, they encounter the dragon and defeat her, allowing Koops's father to get out of the dragon's gut and present Mario with the Diamond Star.
Somewhere else, it is revealed that Princess Peach was abducted by the X-Nauts. When a X-Naut tells Sir Grodus someone got the first Crystal Star, Peach accidentally blurts out Mario's name. Grodus hears this and orders the Shadow Sirens to steal the map in Mario's possession. Peach then meets TEC-XX, who develops an interest in Peach's concept of love, and asks for her help to understand it. Peach agrees; in exchange, TEC lets her send e-mails to Mario. During another scene transition, at Bowser's Castle, Kammy Koopa tells Bowser about Mario's quest to find the Crystal Stars and Peach's abduction, things that motivate Bowser to hunt for the Crystal Stars and kidnap Peach back. Bowser and Kammy then head for Rogueport.
Back in Petalburg, the group receives an e-mail from Peach, who tells them she has been kidnapped. Mario and co. head back to the Thousand-Year Door to reveal the location of the next star.

Chapter 2: The Great Boggly Tree
The second Crystal Star is revealed to be in The Great Tree, home of small creatures known as Punies, deep inside Boggly Woods. When searching for the pipe leading to Boggly Woods in Rogueport Sewers, Mario and his partners encounter Punio, who tells them that the X-Nauts have invaded the Great Tree, capturing most of the Punies and that the Jabbies, the Punies' enemies, have allied with the X-Nauts and are trying to expulse the Punies from the Great Tree. Mario and co. decide to help out the Punies, and therefore Punio leads the group to the Boggly Woods. After getting there, Mario and co. encounter the Shadow Sirens with a necklace, who do not recognize him due to having lost a sketch of him. The group continues and arrives at the Great Tree. However, they realize that the tree is locked. Punio suggests they find Madame Flurrie; to find the secret entrance. However, upon reaching her home, Flurrie reveals she has lost her necklace and does not want anyone to see her without it. After defeating the Sirens and returning the necklace to Flurrie, she joins them in their quest. The group finds the secret entrance and enters the tree; after freeing the locked Punies with the aid of a special orb and after solving the Great Tree's puzzles and defeating the Jabbies, they reveal the second Crystal Star at the bottom of the tree. There, Lord Crump snatches it, and activates a time bomb to blow up the tree. After chasing him to the entrance, he stops the bomb and uses Magnus von Grapple to fight the heroes, but he is defeated by the group. Afterwards, the X-Nauts evacuate the tree and Mario and co. obtain the Emerald Star.
At the X-Naut headquarters, the X-Nauts inform Sir Grodus that Mario has taken the Emerald Star. Meanwhile, TEC-XX calls for the Princess, and asks her to dance with him. TEC then lets Peach e-mail Mario.
Bowser can be seen arriving in Petalburg, and then talking to what he thinks is Peach, but is revealed to be a poster by a nearby Koopa.
As Mario and his team move on, they receive another e-mail from Peach, who tells them that the X-Nauts are searching for the Crystal Stars. Mario and his team reveal the location of the next Crystal Star, and they visit Professor Frankly for details.

Chapter 3: Of Glitz and Glory
The third Crystal Star appears in a large arena on a floating town. To reach Glitzville, Mario and the gang must visit Don Pianta. He offers them the ticket they need after doing him a favor. Once Mario and his team arrive in Glitzville, they enter the Glitz Pit, a popular place in which fighters brawl, and spot the Crystal Star on the Champ's Belt, held by Rawk Hawk, the current champion. They sign up in the Pit, battle through the ranks, and eventually gain a newborn Yoshi as a partner. Soon, a mysterious figure known only as "X" starts sending cryptic e-mails to Mario. The e-mails lead Mario and his partners to discover that the Star on the belt is a fake, and that the real Crystal Star is being used by Grubba, the promoter of the Glitz Pit. Mario & co. expose his wrongdoings and chase him into the arena, where he transforms into Macho Grubba in order to eliminate Mario and his friends. However, the group manages to defeat him. After the battle, Jolene, Grubba's assistant, appears and reveals herself as the mysterious X, explains her story, and gives Mario the Gold Star.
At the X-Naut base, TEC-XX asks Peach to go ask Grodus a question relating to his plans. The Princess goes undercover in an X-Naut disguise and learns that Grodus is plotting to use the Crystal Stars to take over the world. TEC allows her to send this message to Mario. Meanwhile, Bowser and Kammy are searching for one of the Crystal Stars in the Great Tree, where they discover that Mario already obtained it.

Chapter 4: For Pigs the Bell Tolls
Professor Frankly tells the group that the Crystal Star is located in Creepy Steeple, near Twilight Town. When Mario & co. get to Twilight Town, they discover that the village is under a curse cast by a monster who lives in the steeple. Using a new Black Chest Demon power, the group reaches the steeple, and battles the monster. During the battle, the monster uses an ability to steal Mario's name and body, transforming Mario into a shadowy version of himself. Mario's partners claim the Crystal Star and leave with whom they think is Mario. Meanwhile, the Shadow Sirens are in Twilight Town, planning on defeating Mario and his partners with their new weapon: the Superbombomb. However, Beldam seems to have lost it, prompting her to blame Vivian and to force her to search for it. The real Mario returns to Twilight Town, and helps Vivian with her problem. Out of gratitude, she joins Mario's party. They eventually discover that the monster's name is Doopliss. After telling Doopliss his name, he is weakened and flees to Creepy Steeple. Mario and Vivian chase him there and they fight once more. Mario and his new partner defeat Doopliss, allowing Mario to regain his name and body and obtain the Ruby Star.
At the X-Naut base, TEC-XX asks the Princess to participate in a sort of "quiz show" with him. By doing this, she discovers what the "treasure" of the Thousand-Year Door really is: the soul of an ancient demon. The Princess then relays this information to Mario. Meanwhile, Bowser continues his quest for the Crystal Stars by flying to Glitzville in his Koopa Clown Car. However, it malfunctions halfway there, and he travels underwater to return to Rogueport. After he and Kammy return, he orders Kammy to continue her research on the Crystal Stars.
Back in Twilight Town, Mario and his friends receive the message from Peach. They reveal the next Crystal Star and visit Professor Frankly for details.
The Japanese name for the chapter, as well as its English, Spanish, Italian, and French translations, are referencing the Ernest Hemingway novel, For Whom the Bell Tolls. It is also potentially a reference to the Japan exclusive Kaeru no Tame ni Kane wa Naru co-developed by Intelligent Systems which involves a bell capable of transforming frogs into people.

Chapter 5: The Key to Pirates
The fifth Crystal Star is located deep within a pirate's lair on the southern island of Keelhaul Key. To reach the island, Mario enlists the help of Flavio and Admiral Bobbery. They sail to the island with some Toads, Pa-Patch, and Lord Crump in disguise (known as "Four-Eyes"). On their way to the island, Mario and co. are attacked by Cortez's Embers, which shipwreck them on Keelhaul Key. Later on, some of the crew members are attacked by more Embers, and Bobbery sacrifices himself to save them. Bobbery says he is close to death, and after giving him his last request, they find out that he just fell asleep. After Mario wakes him, he joins Mario's party. With the aid of Bobbery and Flavio's Skull Gem, Mario and co. enter Pirate's Grotto. After solving some puzzles, and after gaining another ability from a Black Chest Demon, they finally reach the lair of Cortez. After they battle, Cortez gives Mario his Sapphire Star. Afterwards, Lord Crump abandons his disguise and tells Mario that he will continue attacking him with his ship's cannons until he hands over the Crystal Star. With the help of Cortez's ship and Flavio's Skull Gem, they defeat the invading X-Nauts, along with their leader.
In the X-Naut base, TEC-XX wishes to gain access to a disk in Grodus's room, and asks Peach to help him. After making an invisibility potion, she helps him and he promises to analyze the data. Peach then sends another e-mail to Mario, informing him of this. Meanwhile, in Twilight Town, Bowser and Kammy Koopa run into Lord Crump. The three get into an argument, which escalates to an armed confrontation between the Koopa Troop and the X-Nauts. However, Bowser inadvertently ignites the Superbombomb, knocking out both armies.
Back at Keelhaul Key, Cortez ferries Mario and his teammates to Rogueport. Mario gets the e-mail from Peach, telling them about what TEC is analyzing. Mario and his team then reveal the next Crystal Star's location, and visit Professor Frankly for information.

Chapter 6: 3 Days of Excess
The sixth Crystal Star is in Poshley Sanctum in the town Poshley Heights. The only way to reach the town is on the famous Excess Express. After doing Don Pianta another favor, he gives Mario a train ticket. During the first day on the Excess Express, Mario and his team found many mysterious happenings, including thefts of items and messages threatening to blow up the train. On their second day of travel, Pennington, a Bumpty detective, helps Mario and his friends solve the crimes and they manage to capture a fake Zip Toad who was really Doopliss in disguise, and was the one who attempted to halt the train by causing an explosion with some stolen items. At sundown, when the train stops at Riverside Station for refuel, Doopliss escapes capture. Mario and company find that the drawbridge has been lifted, preventing the Excess Express from continuing its route. The gang enters Riverside Station and flips the switch to bring the drawbridge back down. They discover that a group of Smorgs are behind it. On the third and final day of the journey, a stowaway Smorg monster attacks the train, kidnapping all of its passengers. Mario and his friends defeat the creature, rescuing the passengers in the process, and finally reach Poshley Heights. They venture into Poshley Sanctum, a museum that happens to belong to Pennington. The Shadow Sirens, who happen to be already inside, snatch what appears to be the Garnet Star and flee. However, Pennington reveals that what they stole was a fake, and lets Mario find where the real Crystal Star is. After some exploring, Mario and company manage to find the real Garnet Star.
Back at the X-Naut base, the X-Nauts tell Grodus that Mario has six of the seven Crystal Stars. They also tell him of TEC's betrayal. Meanwhile, TEC tells the Princess the data he gained from Grodus's data disk, and prepares to help Peach escape. Before he is able to, Grodus enters with two X-Nauts and orders them to initiate a data-wipe procedure of TEC's memory. TEC tells Peach "I love you" just before he is shut down.
Meanwhile, Bowser is searching for another Crystal Star in Rawk Hawk's workout room, which he has found in the form of the Champ's Belt. However, he quickly learns that it is not a real Crystal Star, just a glass fake.
Mario and his team return to Rogueport and receive an e-mail from Peach, telling them about what the X-Nauts plan to do with her, but an important part of it is cut off due to TEC being shut down. Back in Rogueport, Mario and co. reveal the next Crystal Star's location and visit Professor Frankly for details.
Chapter 6 appears to allude to Murder on the Orient Express, which also involves several peculiar passengers on a train where a crime takes place.

Chapter 7: Mario Shoots the Moon
The last Crystal Star appears to be on the Moon. To reach the Moon, Mario and his companions travel to Fahr Outpost to find a cannon to shoot them to the Moon. After searching for Goldbob and General White, whose blessings are needed to operate the cannon, Mario & co. enter the cannon and are shot to the Moon.
On the Moon, the group discovers the X-Naut Fortress. Once they arrive at the end of it, Lord Crump appears, bragging about his latest creation — Magnus von Grapple 2.0, and tries once more to defeat Mario and company. After Lord Crump is defeated, the Crystal Star is released.
Meanwhile, Bowser is searching for another Crystal Star in the Poshley Sanctum. A Paragoomba flies in and tells Bowser that Mario has collected every Crystal Star and is heading for the Thousand-Year Door, which contains a great treasure. Bowser announces that he will steal this treasure and defeat Mario.
As Mario and his allies prepare to leave the fortress, they discover that all of the doors have been locked, except for one. In this room, the heroes find TEC, who is running on backup power. He recognizes Mario and tells him to rescue the Princess, who has been taken to the Palace of Shadow, a place that lies beyond the Thousand-Year Door. He then activates an emergency transporter. The group is transported to a room in Rogueport Sewers. After exiting the room, Professor Frankly meets them at the entrance and urges them to open the Thousand-Year Door.

Chapter 8: The Thousand-Year Door
Mario and his friends open the Thousand-Year Door with the seven Crystal Stars, allowing them to enter the Palace of Shadow. The palace itself is full of enemies, puzzles, and traps. Eventually, Mario and co. battle and trounce a dragon named Gloomtail, older brother of Hooktail. After the dragon's defeat, he relinquishes the key to access the Riddle Tower. After solving the puzzles of the tower, a secret passage which leads deeper into the palace is revealed. Mario and his party continue down that path, but not before defeating the Shadow Sirens, who try to get rid of them. Finally, Mario and company reach the throne room of the palace, where they find and defeat Sir Grodus. Bowser and Kammy, who drop in unexpectedly, also battle Mario, but are thwarted in the end. Grodus uses the distraction of the battle to bring Princess Peach into the deepest part of the palace. There, he opens a sealed coffin and frees the Shadow Queen, the ancient demon of legend. Beldam suddenly appears and announces that she was the one who orchestrated the plot to free her mistress. The Shadow Queen refuses to be controlled by Grodus, and fries him with a lightning bolt, apparently killing him. The Queen then possesses Princess Peach, using her as a vessel to sustain her life. The world is then covered in darkness. Mario and his allies fight the Queen, but she eventually decides to fight in her real form, in which she is invincible. She proves too much for the group to handle, however, the Crystal Stars suddenly react to the evil of the Queen and fly throughout the world, each returning to where they were found, allowing the people of the world to cheer on Mario and his party. The hope of the people of the world break through the Queen's invulnerability, and this also allows Peach to give the heroes the last of her power. Strengthened, the heroes seal the Shadow Queen forever, saving the world.
Goombella later sends Mario a message, explaining what everyone has done: she works with Professor Frankly, while Koops plans on becoming the Mayor of Petalburg. Flurrie has returned to the stage and enacts "Paper Mario" as her comeback smash while Doopliss plays the role of Mario. The Yoshi fights in the Glitz Pit as the "Great Gonzales Jr.", while Vivian has forgiven her sisters and lives in Twilight Town. Admiral Bobbery sails the seas with Cortez, and Ms. Mowz runs her Lovely Howz of Badges. Lord Crump, Grodus and the X-Nauts survived and are spending their time in Poshley Heights. TEC survived as well, and hopes to see the Princess again one day. The game ends when the Princess visits the Mario Bros. with another treasure map.

In terms of gameplay, Paper Mario: The Thousand-Year Door brings over the core mechanics of the N64 original and enhances them. Mario now has a voice used for jumping and attacking, and starts his adventure with a hammer. Action Commands can also be performed from the start. However, he has lost the ability to Spin Dash from the original game.
The partner system is also enhanced. Unlike the original, where partners had a simple fine/injured status system, this game gives partners their own Heart Points. As such, partners can fall in battle, and items such as the Mushroom can be used on them as well. Several partners are similar to ones seen in Paper Mario, like Koops being the counterpart of Kooper, but generally have more abilities available. Timed moves are more abundant in this game. In addition, battles are set up on a stage, like a play; this greatly affects battles, and characters can interact with the audience and stage.
Paper Mario: The Thousand-Year Door brings up new gameplay elements not present in the original Paper Mario game. Throughout the game, Mario finds four black treasure chests, which give Mario special abilities to use in the overworld. They all base on the Paper element of the game's graphics. With the first ability (called Plane Mode), Mario is able fold himself to a paper airplane at certain spots, allowing him to fly over large gaps. The second ability (called Paper Mode) allows him to turn sideways, making him as thin as paper, so that he can get through very narrow passages. With the third ability (called Tube Mode), Mario can roll himself up, allowing him to roll through low passages. With the fourth ability (called Boat Mode), he can fold himself to a paper ship at certain docks, allowing him to move over water. It is noticeable that, to use Tube Mode, Mario has to activate Paper Mode first, and then roll himself up.
Another element introduced in Paper Mario: The Thousand-Year Door is the background scenery, which is actually accessible for Mario through certain pipes. Several places which only appear in the background can be visited this way, some of which include Hooktail Castle, the Great Tree, the X-Naut Fortress, and Merlee's house in the Rogueport Sewers. This feature was carried over to the next game in the series, Super Paper Mario. Certain abilities are disabled here, however. Mario's partners cannot be used in the background, Mario cannot move to a different screen/area, and he also cannot walk past any houses or locations.
After each chapter, there is an intermission where the player is able to control Princess Peach, who is held captive in the X-Naut Fortress. The Peach intermission is followed by a Bowser intermission, a new addition in Paper Mario: The Thousand-Year Door. Bowser usually visits the places Mario has been to one chapter before, and several missions include a side-scrolling platformer level in the style of Super Mario Bros.. In these levels, Bowser has the ability to breathe fire, and by using the only available item, the Meat, is able to radically increase his size, allowing him to crush everything in his way. While enemies like X-Nauts charge at Bowser, others like Goombas are actually scared by him and turn away when he approaches them. The levels are called 1-X, 2-X and 3-X in reference to the world numbering of Super Mario Bros., while X stands for the number of tries Bowser has used for the level. He has endless lives for the levels. They are set in the three basic terrains of Super Mario Bros.: Overworld, Underwater and Underground/Castle.
Battles take place on a stage. In addition to the traditional turn-based combat, the characters on-stage interact with the scenery: sometimes the background will fall, damaging all characters on stage and possibly making them Dizzy, the audience helps Mario gain Star Power and also may throw items on stage or attack Mario and his partners, and lastly, some bosses even use the audience to their advantage. For example, Hooktail eats some of the audience to regain 10 HP, also causing all other audience members to flee, making it impossible to gain any Star Power. In addition, the battle shifts off-stage.
While Mario and his partners are battling enemies, they can attack enemies with extra power using various Action Commands. Stylish Moves are extra commands to please the crowd more and gain more Star Power.
To perform a guard action command, one must press or when Mario's opponent is about to strike him. Guarding reduces the damage he takes from enemy attacks and help the player resist status effects. The player must time it right, though.
Guard: To perform a Guard move, the player must press to dodge enemy attacks, reducing the damage they do by 1, and also protecting Mario from negative status effects. The player will have 8 frames (roughly 2/15 of a second) to guard.
Superguard: To perform a Superguard move, the player must press to dodge enemy attacks, negating the attack completely and sometimes damaging the attacker--generally a Superguard deals 1 damage to an enemy who attacks directly and none to foes who attack at range, but it does deflect Pokeys ranged attacks back at them. The player will only have 3 frames (or 1/20 of a second) to superguard, making it more difficult to time than a regular guard.
Every time Mario wins a battle, he will earn Star Points. When Mario's Star Point Level gets up to 100, the player can choose whether to upgrade Mario's Heart Points, Flower Points or Badge Points. Upgrading HP or FP will increase the upgraded stat by 5 and choosing BP will raise Mario's BP by 3. Mario stops levelling up at 99. Each stat has its own maximum value, which it cannot be upgraded beyond. For HP and FP, this value is 200, but for BP, this value is 99; however, it is impossible for the player to have all three stats simultaneously be at their maximum value at any one time, since the lack of level ups prevent at least one of the stats to be at its maximum.
Much like Paper Mario, there are items found in the overworld of Paper Mario: The Thousand-Year Door that, when collected, allow Mario to upgrade his partners to learn new moves and increase their HP. In this game, Shine Sprites fulfill this purpose. The price of upgrading a partner is always three Shine Sprites. There are 42 Shine Sprites altogether in the game.
The Audience determines how much Star Power Mario recovers. It consists of various enemies and allies, and sits and cheers as the group attacks. If Mario or his allies use the Appeal action or a Stylish Move, they will recover more Star Energy. The audience is even used by various bosses. Hooktail, Cortez, and the Shadow Queen all use the audience to restore their HP. Magnus von Grapple 2.0 can also use members of the audience to attack by launching them at Mario and his partners.
The Audience occasionally takes active participation in the battles; some spectators throw helpful or hurtful items, while others may incapacitate other audience members, making Star Power recovery more difficult.
An icon will appear next to Mario's Star Power Gauge whenever the player successfully uses the Action Command of an attack. If the player has two matching icons and if the player executes an additional Action Command, Mario can take the Bingo wheel for a spin.
Throughout the game, Mario, just like the past game, uses partners. His partners have purposes in both the overworld and battle. They can be upgraded by Merlon by giving him 3 Shine Sprites. Every partner knows two moves upon joining the party, learns the third after being upgraded to Super Rank, and masters the final move after attaining Ultra Rank. Initially, each partner may only be upgraded once, but upon finding the Up Arrow in Hooktail's Castle, Merlon will remember he has an Ultra Stone, subsequently allowing the player to upgrade a partner for a second time.
Items are objects that help Mario and his partners on his journey. Most of them change and heal his stats such as Heart Points (like Mushrooms), Flower Points (like Honey Syrup), Attack (like Power Punch), Defense (like Courage Shell), and some give the player status boosts (like Repel Cape), but some damage the enemy (like Fire Flower) and/or give them status ailments (like Mr. Softener). Mario may hold on to 10 items on his body but he can store 31 items at any Item Shop and withdraw them at any time there. The amount of items Mario can hold will be doubled after he collects the Strange Sack.
Badges are objects that Mario and his partners can use throughout the course of the game. They can be purchased at the Lovely Howz or by Charlieton, traded for Star Pieces by Dazzle, won at the Pianta Parlor or found in one of the places Mario and company visit. The blocks in which badges are found in the field are red in color, unlike normal item blocks which are yellow.
When leveling up, Mario can gain Badge Points (BP) which allow him to use badges he has already found. Some of the badges add new Jump or Hammer moves to Mario's commands during battle and other new abilities.
Badges can also affect Mario and his partners outside of battles. After the battle certain badges can increase the amount of coins, flowers, hearts, or Items enemies drop. Enemies might also carry badges in battle, which only Ms. Mowz can steal right away, and there is a likeliness that they might leave them when they are defeated.
Two special badges, the W Emblem and the L Emblem, can change Mario's clothing. With the W Emblem, Mario gets Wario's clothing, with the L Emblem, he gets Luigi's clothing, and with both Emblems combined, he gets Waluigi's clothing.
If multiple copies of the same jump or hammer badge are worn at once, the FP requirements will increase exponentially, whereas the attack power will increase linearly.
During the adventure, Mario and co. can collect Star Pieces by finding them in hidden spots, underneath chambers which he can use the Spin Jump to reveal, and earning them from other characters. Ms. Mowz is useful in finding the overworld Star Pieces. Mario can then trade them with Dazzle for Badges. There are 100 Star Pieces in the game.
In Mario's adventure in Paper Mario: The Thousand-Year Door, he will encounter enemies on the field. When he engages battle with them, there are often other enemies that accompany the one that Mario encountered on the field.
Hidden block locations
In Paper Mario: The Thousand-Year Door, Mario can sell items from his inventory to shopkeepers in the item shops in the game. Most items can be sold to the shopkeepers for a set price at every shop, however, some items will sell at a higher price depending on the location of the shop and the item itself. Mario can make a profit if he purchases an item at a low price from one store, and sells it to another that will buy it from him at a higher price. One Trouble Center trouble exploits this fact.
Star Point amounts
When Mario defeats enemies or bosses, he is awarded with Star Points at the end of the battle. How many he earns from each enemy or boss depends on his current level compared to the enemies he earns them from; as his level goes up, he earns less Star Points from them. If Mario's level is just under, matches or exceeds the enemy's, or reaches the maximum level, 99, he will not earn any Star Points from them at all.
Zess T. Recipes
Mario first breaks her contact lens in the Prologue. After Chapter 2, Mario bought her a new one, and she returns home. Mario can ask her to cook something. After completing her Trouble Center trouble, she will be able to cook two items at once.
Bestiary (Tattle Log)
Trouble Center Side Quests
In Rogueport, there is a Trouble Center which offers the citizens' troubles for Mario to solve. An anonymous quest comes from Ms. Mowz and requires Mario to find a badge she is looking for but can not find. After this quest is completed, she joins Mario's team.
Bold signifies chapter bosses.
The Pit of 100 Trials
The Pit of 100 Trials is an optional challenge. Before or after saving the world, Mario can take on the enemies found in the 100-basement floor area known as the Pit of 100 Trials. The enemies located on levels 51-99 are especially strong. Upon reaching floor 100, Mario discovers Bonetail, the long-lost relative of Hooktail and Gloomtail. After defeating Bonetail, Mario receives the Return Postage Badge.
Similarities to Paper Mario
There are many similarities between the original Paper Mario and Paper Mario: The Thousand-Year Door, including these elements:

Pre-release and unused content
This game was initially titled Paper Mario 2 and featured a far different logo, one reminiscent of the original Paper Mario's logo.
Part of the original trailer shows an extra ledge above the pipe in the room directly east of the Thousand Year Door, with an HP Plus badge on it. It could be accessed via a moving platform which had a wall over it halfway, which appeared to be passable with help from Vivian. Also, Beldam and Doopliss were originally going to be fought somewhere in Riverside Station. The trailer also showed that Item Shops would be labeled with Mushrooms, much as in Super Paper Mario, rather than the Fire Flowers seen in the final game. Red Bones was initially named "Red Koopa Skeleton". In the same trailer, one can see that "Tornado Jump" was initially called "Hurricane Jump". The status element Slow had a different icon, a snail instead of a sad purple face.
Koops Splashing on Dry Land
At the dock of Rogueport, the player should stand on or near the bollard and use Koops's ability, holding so he remains in place. Without letting go of the button, the player should walk away so that Koops is offscreen, and talk to a character in the same area. When the player is done, Koops will respawn next to Mario. There will be a splash animation even on dry land. This glitch also works in Petalburg.
