Super Crown

A Super Crown is an upcoming item that is scheduled to make its debut in New Super Mario Bros. U Deluxe. So far, the only effect that it is known for is to transform Toadette into Peachette, a Princess Peach lookalike that gives her the ability of a Double Jump akin to Princess Daisy in Super Mario Run, and perform Peach's Floating Jump. Additionally, she automatically gets boosted if she falls into pits.
