** It's also possible to obtain Ms. Mowz as early as chapter 2 thanks to this glitch. Once you obtain the Super Boots you have to perform this glitch in order to access the pipe that leads to Poshley Heights and check the door of Poshley Sanctum, which will trigger the cutscene with Pennington and cause the game to move forwards all the way into chapter 6. Once you do that, go to the Trouble Center in Rogueport and you will see that all the troubles available up until chapter 6 have unlocked. Complete Ms. Mowz's trouble and gain her as a party member. Now go back to the area with the cage and the fake pillar inside the Great Tree to set the game back to chapter 2 and you'll find out that Ms. Mowz stays with Mario the rest of the game. She even stays with Mario after Doopliss steals his identity (granted, you have to get Vivian first in order to be able to use her abilities again), allowing Chapter 4 to have a party consisting of Mario, Vivian and Ms. Mowz.

* The Hazard respawn glitch requires you to jump the very first frame you enter a room or after a previous jump, in order to not allow Mario's previous position to be updated. As a result, if you encounter an overworld hazard (like Piranhas in any water), the game will respawn Mario at the room's co-ordinate 0,0. Using this in the Rogueport Sewers can allow you to open the Fast Travel pipes early, provided you have the Super Boots; or access the pipe to Petal Meadows without fighting Blooper.

* The Hazard respawn glitch requires you to jump the very first frame you enter a room or after a previous jump, in order to not allow Mario's previous position to be updated. As a result, if you encounter an overworld hazard (like Piranhas in any water), the game will respawn Mario at the room's co-ordinate 0,0. Using this in the Rougeport Sewers can allow you to open the Fast Travel pipes early, provided you have the Super Boots; or access the pipe to Petal Meadows without fighting Blooper.

* DevelopersForesight actually prevents an obvious sequence break in Chapter 4. There's a character who can only be defeated [[IKnowYourTrueName if you know his real name]]. The game pulls up a text entry screen so you can guess his name. Initially, you have no idea what it is, and have to go on a quest to find out. [[YouShouldntKnowThisAlready And if you know it anyway because you've played the game before or looked it up]], he went ahead and ''[[ImpossibleTheft stole one of the letters in his name straight off the text entry screen]]'' (and yes, it's case-sensitive). You learn what his name is in the same room that you get the letter back.

As a result, if you encounter an overworld hazard (like Piranhas in any water), the game will respawn Mario at the room's co-ordinate 0,0. Using this in the Rougeport Sewers can allow you to open the Fast Travel pipes early, provuded you have the Super Boots.

* The fight against the Shadow Sirens in Chapter 8 can be skipped rather simply by jumping over a railing on the small footbridge leading up to the fight, avoiding the trigger for the fight.

''VideoGame/PaperMarioTheThousandYearDoor'' contains many instances of SequenceBreaking that allows many chapters to be skipped, {{Dungeon Bypass}}es to be done, and to obtain certain items earlier than expected, allowing the game to be finished in under three hours.

* You do not have to get all seven crystal stars to unlock the titular Thousand-Year Door leading to TheVeryDefinitelyFinalDungeon - it's merely the seventh crystal star alone that does the trick.
* Chapter 2 contains multiple skips that allow many of the events within to be skipped.
** The Cage Skip is the most prominent of these, allowing players to clip into a wall and then into the floor in order to avoid a scene where the Punis are trapped in a cage and enter a pipe on an otherwise insurmountable platform.
** Normally, when Mario loses control over the Punis, the Puni counter will go down. However, jumping continuously after falling off a ledge (or when clipping downwards, such as during the Cage Skip) allows you to retain control over the Punis and prevents the Puni counter from going down even if you are very far away from them and they do not physically follow you. This allows many puzzles involving transporting the Punis to a faraway pipe to be effectively nullified.
** Jumping backwards when in control over Punis will also let Mario retain control of the Punis even as they do not follow him, skipping even more puzzles.
** A scene where 11 Punis face off against 10 Jabbis can be skipped by clipping into the walls of the room where the battle occurs and walking along the wall to the other side of the room.
* Speaking of the seventh crystal star: Chapter 7, the chapter where you're supposed to be blasted off to the moon from Fahr Outpost, can be accessed early by clipping ''[[ViolationOfCommonSense under]]'' a bar in ''Rogueport'' of all places. (The trick is that you clip towards where the game internally placed the teleporter you're supposed to use to ''return'' from the moon, which is in the Rogueport sewers.) This allows you to completely skip a backtrack-heavy quest involving awakening General White in order for him to operate the cannon to the moon. This can be done in various ways, depending on the partners and version of the game used.
** The most popular method, only possible on the original Japanese version, is to have Flurrie blow you downwards while in the bar's doorway, causing the clip.
** Another method, viable for the English version as well, involves the storage glitches to accomplish the clipping, but performed on the exterior of the bar instead.
* A complicated series of glitches, collectively known as the Palace Skip, allows you to literally fall through the floor with SomeDexterityRequired in the hallway preceding Gloomtail to be dropped off only two rooms away from the Grodus, Bowser, and Shadow Queen final boss fights, skipping much of TheVeryDefinitelyFinalDungeon.
* A boss fight against the Shadow Sirens in the VeryDefinitelyFinalDungeon can be skipped by jumping over a railing on the small footbridge leading up to the fight, causing you to land on the ground away from the small area immediately in front of the bridge that triggers the boss fight.
* The Jump Storage or Super Jump glitch, caused by making the event flags associated with a jump fail to complete, allows Mario to fly to ridiculous heights as long as he can find a location on the game's scenery where his y-coordinate (vertical) position increases by walking on it, and then holding A. The event flag discrepancy can be triggered by a text storage glitch. This glitch can be used to derive many other sequence breaks, such as flying over fences and walls, levitating on top of platforms supposed to be out of reach, among others.
* Discovered in a period between Spring 2018 and Spring 2019, the Blimp Ticket Skip, where you can use the Jump Storage glitch to fly past the fence and the Cheep-Cheep blocking the blimp to Glitzville, allows you to finish Chapter 3 without obtaining the blimp ticket.
* Chapter 3 can be shortened dramatically by performing any skip in Chapter 2 that leaves an EventFlag behind, getting the Super Hammer in Chapter 3 and then lowering your Glitz Pit rank to 16. Then, backtrack to Chapter 2 and trigger a leftover EventFlag, and finally return to Chapter 3 for Grubba to re-introduce you to the Pit, but this time say no to his offer to join. This allows you to run around Grubba's office freely, jump up to a bookcase to enter the AirVentPassageway on top and thus trigger the boss fight against Grubba to spawn without becoming the Champion.
* Ms. Mowz, an optional party member, can cause a glitch that allows Mario to control his movement direction while being launched sky-high whenever he falls into any body of water, allowing him to jump to places normally too high for him to reach.
* The Ultra Hammer can be obtained earlier than expected via two ways:
** Activating the Jump Storage glitch allows you to fly up to the chest that contains the hammer, which is positioned on a very high platform in Rogueport. This method is viable in all versions of the game.
** A Japanese-version-exclusive method has Flurrie blow Mario into the wall of the house right behind the Ultra Hammer chest, allowing Mario to clip through the building to reach the now-invisible hammer chest (but the hammer itself remains visible).
* A scene in Hooktail Castle where you have to hammer away a large mass of Dry Bones to uncover a Red Bones can be skipped with a frame-perfect jump at the right moment when you approach the Red Bones as it initially lies in front of the door it guards. This tricks the game into thinking you're about to trigger a battle with the Red Bones, because while the cutscene pushes you backwards, the game still thinks you are at the door where the Red Bones was.
* Pirate's Grotto can be entered without bringing Flavio to the entrance (who gives you a jewel needed to solve a puzzle at that point) by using a glitch to clip into the wall surrounding the room where the entrance is. After reaching the right end of the room while in a clipped state, Bobbery can blow open the way in.
