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

These are the glitches found in New Super Mario Bros. U.

This glitch can be done in Iggy's Volcanic Castle, when the player fights Iggy Koopa, when he is on the top roof, once he falls off it, Mario must immediately jump on him, and he will then go into his shell, but another one appears and will be faced sideways.
