List of Mario & Luigi: Paper Jam glitches

This is a list in glitches in the game Mario & Luigi: Paper Jam.

Out of Bounds
Out of bounds glitches are some of the most common ones in the game, and occur when the player manages to get the trio outside of the normally explorable game world. Once this is done, they can walk through waters, across water, air or lava and skip a significant amount of cutscenes and boss battles, depending on where it occurs.

Out of Bounds in Twinsy Tropics
Near the Lakitu Info Centre in Twinsy Tropics, there's a piece of coastline just south of a bridge near the right of the area. If the party stands on the very edge of the land near the beach and uses the Trio Grab, and then starts walking along the edge, they'll start shaking rapidly before falling off onto the water nearby.

At this point, if they head towards the bridge to the right while not in Trio Grab form, they'll be warped onto it and can exit right. However, if they're not in Trio Grab form, the game will freeze when they try and walk under the bridge, with the only option being to make Mario jump onto the bridge and get stuck even more. At this point, the player will have to reset to the Home Menu to exit the game.

This can also be done in a mission (like Tropical Toad Hunt), which will then lead to various additional effects if they exit the mission area. These include all actions except Jump, Hammer and Trio Grab being disabled until the game is restarted, the game freezing with no music if they try and play another mission, the save option being replaced with the ability to exit the mission and extra obstacles (like a wooden fence) being added to the game world.

If they go to the Lakitu Arcade, the mini games, Battle Ring and Papecraft Battle Ring will still work as normal. However, because the game saves after one of these is completed, it means that the world will permanently be stuck in the state it was in during the mission if the save file is reloaded from this point. So the fence blocking the path to the left of the Lakitu Centre will be there permanently. This means the path between the Toad Village and the info centre is now impassable without glitches.

Warp pipes, shops and enemy battles work as normal, but beating the final boss will send you back to the Lakitu Info Centre after the credits. At this point, the player can check their inventory, character statuses, collection options, etc, but cannot move Mario, Luigi or Paper Mario or exit the area. The option to save returns at this point, but using it will likely render the save file unusable.

Paper Boat Skip
By going right from the Lakitu Info Centre, the player can find some rocks near a section of beach and ledge. By walking into these carefully with the Trio Grab, and then pressing Y and moving the circle pad around, they can get Mario and co through the obstacle and onto the ocean nearby. This lets them avoid having to use Trio Drill or Trio Plane to get past the nearby paper terrain, and can be used with another out of bounds glitch in the Doop Doop Dunes beach area to avoid having to use the boat altogether.

Berries and Yoshi Race Skip
In Gloomy Woods, in the left of the first area where the berries and trees are, the trio can stand on the edge of a tree stump and use Trio Grab to walk on the bottomless pit next to it. By heading north to the next area, they can skip collecting the berries or racing Yoshi.

Mount Brrr Tunnel Skip
Prior to the paper terrain appearing to the left of the Toad Village on Mount Brrr, the player can make Mario and co use the Trio Drill to dig in the area to the south west of the Lakitu Info Centre. They'll get nearer the wall than usual by doing this correctly, at which point jumping out the ground and using the Trio Grab in the right location will let them walk through the nearby fence and into the sky beyond. This can act as a shortcut to either the pipe behind the Lakitu Info Centre or the tunnel leading to the upper part of the summit.

It can also be done in certain missions, like Paper Toad Freeze-Out, at which point the side effects mentioned in the Twinsy Tropics Out of Bounds glitch will apply here as well.

Pokey Boss Skip
In the far top left corner of the area with the bridge and Pokey bosses, there's a ledge with an unusual rock formation to the right. By moving Mario into the rocks and changing between holding up left and up right on the Circle Pad, the player can force the party into the rocks and out through the wall behind. At this point, they can walk off screen past the Pokeys to avoid having to battle them or cross the nearby bridge.

Mount Brr Shortcut
In the uppermost area of Mount Brrr, there's a cloud with a Biddybud and bridges to the north and right. By using the Trio Drill here and charging at the edge of the rightmost bridge, the party will be launched into the air and end up digging through the sky above. If they go left or down, they'll land on the wooden bridge while underground, letting them dig inside the bridge. By going right and up however, they can walk across the air to the other clouds, potentially skipping part of the area.

Reach Mount Brr Summit Without Plane Ability
By using Trio Drill on the vertical dirt walls in the passage leading to the summit, then dropping down near the wall, you can clip inside it. At this point, using Trio Grab will let the trio teleport to the higher edge, or even just some point high in the air. They can use this to exit the tunnel without using the plane ability.
