Princess Peach: Showtime!

A game featuring Princess Peach as the main protagonist is set to release on the Nintendo Switch in 2024. It is her first starring role in the franchise since Super Princess Peach.

The game has a stage play-themed setting. Peach is accompanied by a new, currently unnamed sidekick resembling a comet with a green ribbon tail, who can turn into a long ribbon she can use to interact with on-stage elements, such as props and characters. Notably, Peach wears her hair in a ponytail, tied with a magenta bow. She also appears to be missing her crown.

In Nintendo's financial report for the first quarter of their fiscal year ending 2024, the game is listed in the launch schedule as "Princess Peach will star as the main character in a brand new game". This sentence is explicitly treated as a tentative title for the game.

Development
The game was first teased during the June 21, 2023 Nintendo Direct, alongside Super Mario RPG and Luigi's Mansion: Dark Moon. Also teased in the trailer was a new transformation Peach undergoes during the game, which turns her dress pale blue if she stands on a particular spot on stage. During the transformation, her sidekick turns into a ribbon and twirls around her, taking the color of her dress.
