List of Paper Mario glitches

This is a list of glitches in the game Paper Mario.

Treasure Room Freeze Glitch
In Bowser's Castle, if the player tries to enter the room with the door to the treasure before the lava has been cleared, they will take damage while also triggering the enter area script. The treasure room will appear, with Mario nowhere to be found; the game will freeze a second after the player entered the room, crashing into a debug screen.

Herringway Glitch
Using the, Herringway can be morphed into a normal Bumpty or become invisible. This can be performed when the player pauses the game right after Mario and Herringway go into the mayor's room; this can also be done right before initiating a conversation with the detective during Chapter 7. If invisible, he will reappear when the room is left. If Herringway becomes a normal Bumpty, the game will freeze when the mayor gives him the present, and a debug screen will appear; this was fixed in the Virtual Console release.

Koopatrol Princess Peach
In the Chapter 6 event during the Intermission, if the player times the parasol right when the Koopatrol spots Princess Peach, she becomes a Koopatrol, but they still treat her as Peach. This also works on a Hammer Bro in the library; this is the result of a lack of landing sprite for the Koopatrol.

Li'l Non-Sparky
If Watt uses her Electro Shock on an enemy and it fails to do any damage, she will not have any lightning bolts emanating from her, which performs the glitch. This has been tested on fake Magikoopa clones and Bowser under the influence of the Star Rod.

Shiver Region Toad to Normal Toad
In Shiver City or Starborn Valley, the player should go into the Toad House and take a nap. After the nap, the player should pause the game. The Shiver Region Toad should then become a normal Toad. This does not affect anything within the game.

Swim Out Of Bounds
To, the player must go to the very end of the snow in Shiver City, then jump and hold or repeatedly tap C Down. If done correctly, Sushie will land under the dock. Mario and Sushie can then swim anywhere, but can not enter pipes. The glitch ends when Mario goes back to the dock.

If Mario tries to go to Shiver Mountain, they will land in ice and cannot hit the switch. If Mario goes to the Frost Piranha-populated part of Shiver Snowfield, they cannot get past, and if they go down the slope, it will be impossible to get out.

Disappearing Parakarry
At the bridge connecting Goomba Road and Toad Town, there is a glitch in which Parakarry can disappear for a couple of seconds. First, the player must walk down the staircase, then spin towards a corner with a bush. If this is done correctly, Parakarry should disappear for one or two seconds.

Out of Bounds
The glitch makes it possible to move off the screen using small passageways, or a glitching Trampoline. The best chance to do this is at Mario and Luigi's home, in the secret basement. The player must set Kooper as their partner, stand behind the Trampoline, and hold the control stick down while dashing with. After that, Mario will jump to the normal floor of his house, then immediately under the secret basement. Mario will then again appear behind the spring board.

Sliding Mario
Mario can be stuck in his talking pose after the character starts talking. If the player starts talking as Mario is going up onto a ledge, Mario will be moving while the character is talking. If the player goes up onto the ledge, Mario will go back to normal after going back down, but if the player stays down, none of the controls will work and the game will have to be reset. The glitch works best in Kooper's house in Koopa Village.

Stuck Parakarry
If Mario interacts with the fireplace in Boo's Mansion while Parakarry is the active party member, Parakarry will continue to fly in place without following Mario. The glitch will end when he is switched for another partner,  is pressed, or Mario leaves the room.

Unwinnable Bowser Fight
The introductory battle against Bowser is supposed to be unwinnable. As a result, the game cannot register victory animations and such. If the player manages to defeat Bowser at the beginning of the game, the game will freeze on a static image of the sky.
