List of New Super Mario Bros. U and New Super Luigi U glitches

This is a list of glitches in the game New Super Mario Bros. U.

This glitch can be done in Iggy's Volcanic Castle. When Iggy Koopa is on the top roof, once he falls off it, Mario must immediately jump on him. He will then go into his shell, but another one will appear and be faced sideways. The glitch turns off in a few seconds.

This is recommended to do in Walking Piranha Plants! if Nabbit is there. The player must start with a Star and chase him to one of the first pits. The player has to grab him then fall. On the screen, it will say "Nabbit got away..." even though he did not. When the player comes back to Rock-Candy Mines, Nabbit is still ready.

This glitch only works in Boost Mode. When Kamek uses his magic in his boss fight to create blocks, the player has to put a Boost Block on top of him and jump below it. Kamek will fly off the screen, making the battle unable to be beaten. This glitch works for almost any boss battle.

The player should wait until the very end of the Time Limit on a Warp Pipe. If Mario enters the pipe exactly when the time changes from 001 to 000, he goes to the other side of it, and the timer will remain stopped at 000 until the plumber touches the Goal Pole or exits the level. This goes the same for time Challenges on Challenge Mode. If one enters a door at the time where it turns from 001 to 000, they won't die as well.

This only works on New Super Luigi U. The player should repeat the above glitch, but with a boss door. The player will then have exactly 100 seconds to defeat the boss. However, no music is heard, although the boss' sound effects are kept.
