New Super Princess Peach U (title styled as New Super Mario Bros. Princess Peach U) is a downloadable expansion for New Super Mario Bros. U by AdamGregory03 (talk), as well as the second expansion pack for the game, the first being New Super Luigi U.


The gameplay is identical to the gameplay of the source material, however, the playable characters now have the ability to hover midair for a short period of time, similar to Princess Peach's special abilities in Super Mario Bros. 2 and Super Mario 3D World. Nabbit has been confirmed to return as a playable character, playing very similarly to how he did in New Super Luigi U.


Princess Peach has invited Daisy and Toadette for some tea and "girl time" while Mario and Luigi have gone away. However, Bowser and his Koopalings attack with a gigantic airship, and a giant mechanical claw grabs the two princesses and Toadette and flings them all the way to Acorn Plains, taking over Peach's Castle. This makes Peach furious, and the three set off to take the castle back, not noticing Nabbit following them.


A * means it is not confirmed.
