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 to Double Jump, and perform Peach's Floating Jump, somewhat similar to how the Flying Squirrel powerup functions. Additionally, she automatically gets boosted if she falls into pits.
