List of Mario & Luigi: Partners in Time glitches

This article lists the glitches found in Mario & Luigi: Partners in Time.

After one of the crew members states that a transmission is received from Princess Shroob, Baby Bowser asks them to show it in the crew member's voice.

During when the L33t Hamm3r Broz. teach Baby Mario and Baby Luigi how to counterattack with the hammer, if Baby Mario lets go of the X button before L33t Hamm3r Broz tell them to, the game will glitch but not freeze. During this glitch, the music will keep playing, the Spiny Shroopas and the babies will keep doing their battle poses, but the X symbol will remain on the screen and the Hammer Bros. will not continue their explanation.

When training on how to jump with Mario and Baby Mario or Luigi and Baby Luigi and everyone gets high POW, if one of them jumps on them, the adult character and the baby character might jump back, and they will stand and look at the ghost forever. The only way to stop that is by turning off the system or restarting all over again.

If the game is paused while on-screen enemies are performing certain motions (usually spinning), they will be unable to move when the game is unpaused. Everything else will work normally.

Anytime after opening the Time Hole to Toadwood Forest, the player must throw the babies into the Time Hole first and let the adult Bros. The player need to follow automatically, as usual, but, if the player look at the top left corner of the screen, before the big Bros. fly out after the babies, they can see Luigi facing away from the screen standing on the purple liquid just barely on-screen.

The top of Princess Shroob's statue is a control room that detaches for a minigame where the player battle the Shroob Mothership. After the minigame, the control room returns to its place to let the player off. At the Save Album nearby, save and quit, and the control room won't be on the map when reloading the game. It will reappear on the map after defeating Princess Shroob or if using the Warpulator. This glitch is harmless because the player can still enter the control room if it's missing from the map.

This glitch only works when the player is controlling the adult Mario brothers. At the beginning of the fields near Hollijolli Village, the player should head over to the trees in the top left corner and walk behind them. Continue moving up and down as well as forward after heading back as far as possible. If done correctly, the player should head back farther, as well as seeing Mario standing on top of the trees. If the player moves away, the glitch ends; vertical movement does not affect it.

Throwing the babies into the two Save Albums where Stuffwell lets the Bros use his Warpulator, will cause the action icons to go crazy for a short time before disappearing. Normally, the icons smoothly move upwards and off-screen when hitting these Save Albums.

Note: This glitch is only present in the U.S. version.

In the Koopa Cruiser, Go walk at the left edge. When the Koopa calls the baby's, Baby Luigi walks to him, but Baby Mario stays, making a motion like he walks.

In Thwomp Caverns, use the Baby Spin in the cyclone. If Baby Mario lands on the ?-block on the left platform, Baby Luigi stays there, and Baby Mario warps to the platform above. You can't enter piggyback mode now or change to the adults. This glitch can be fixed by moving Baby Mario into the spikes, which will take both the baby's to the platform above.
