Peachette

Peachette is a unique form of Toadette, obtained by grabbing the Super Crown in New Super Mario Bros. U Deluxe. Upon obtaining the Super Crown to transform, she highly resembles Princess Peach but has a different dress, a Toad cap-like crown, gray irises, pigtails, and Toad-like shoes.

New Super Mario Bros. U Deluxe
Peachette first appears in New Super Mario Bros. U Deluxe. In this form, Toadette is able to Double Jump, and can also perform Peach's Floating Jump, identical to how the Flying Squirrel form functions, although she cannot cling to walls. She also gets boosted out of any pits, lava, or poison that she falls into, though only once. If Peachette tries this twice in a row, she will fall into the hazard and lose a life.

Super Smash Bros. Ultimate
Following the version 3.1.0 update released on May 30, 2019 and during the "Super Smash Sisters" event that ran from May 30 to June 4, for Super Smash Bros. Ultimate, Peachette was made available in the game as an Ace-class Shield-type primary spirit, though she was accidentally revealed a week earlier on May 21. In her spirit battle, the player was required to defeat Peach, Mario, Luigi, and a Mii Brawler dressed as Toad on Mushroom Kingdom U within one minute under the effects of low gravity and a higher launch rate.

Mario Kart Tour
Peachette is playable in Mario Kart Tour (marking her debut in the Mario Kart series), as a separate character from Peach and Toadette. She is one of three starter characters in the game, with the other two being Toad and Toadette. If Peachette is not given as the player's starting character, she is available as an unlockable High-End character instead. Her special item is the Mushroom Cannon, continuously shooting mushrooms from the front of her kart for her and the other racers to pick up. In Mario Kart Tour, Peachette can be upgraded up to 800 points and has an advantage on Dino Dino Jungle R, Mario Circuit, Toad Circuit & Toad Circuit T.
