New Super Mario Bros. U Deluxe is a 2019 Nintendo Switch side-scrolling platform game released on January 11, 2019. It was announced at Nintendo Direct on September 13, 2018. It is the latest game in the "New Super Mario Bros." series and the follow-up of the 2012 Wii U launch title "New Super Mario Bros. U" and its 2013 extension pack "New Super Luigi U" (also released on Wii U). The game adds two new playable characters, Nabbit and Toadette. A power-up called "Super Crown' is a power-up for Toadette, which causes her to transform into a character that resembles Princess Peach, Peachette. As Peachette, she can float like Princess Peach in Super Mario, double jump like Daisy, and recover if she falls in a pit or lava.
