If you’ve been wondering how to add her to the list of characters, we’ve got everything you need to know about doing so in the guide below.
First, finish the main game by clearing World Bowser and getting 170 Green Stars. After that, one of the Sprixies will leave a rocket in World 1.
Interact with the rocket, and go to 3D World’s first bonus area, World Star. Then complete World Star-1, Rainbow Run. Like all bonus locations in the larger series, the stages here have a noticeable increase in difficulty.
Star-1 includes a color-switch platform challenge, Plessie ride with no guard rails, fast-rotating platforms, and more. The catsuit offers some insurance with the platforming challenges.
After beating that level, move on to World Star-2, Super Galaxy. It features a number of Octo Goombas and long stretches of rotating platforms.
If you don’t have a cat bell and don’t feel like finding one, using a Mario-series amiibo offers a random power-up and might be worth a shot if you’ve got one lying around.
The teal princess unlocks automatically once you clear World Star-2. Unlike other characters, she has a default spin attack that knocks out nearby enemies. However, the attack disappears once she obtains another power-up. Aside from that, she plays roughly the same as 3D World’s other characters.
That’s all you need to know about how to unlock Rosalina in Super Mario 3D World, but stick around for more Mario 3D World guides in the coming days.
