Nintendo Austrailia accidentally posted some content that they probably shouldn't have about Super Mario Odyssey today, because the page showing off some new updates was quickly taken down. However, that didn't stop Twitter from capturing it. Shortly before the content was taken down, Nibel managed to snag these photos from the update.

As you can see, there's a new mode for Luigi coming in the form of Balloon World, which is a competitive game where Luigi will hide a balloon somewhere in the level and it is up to you to locate it within 30 seconds. Along with that comes some cosmetic changes as we see Mario is being decked out in some new Hawaiian gear for the beach, along with a zuit suit for that old-school gangster look, and a suit of armor just in case Mario might run into some other form of dragon he needs to slay. Originally, the info on the update said it would be available on February 23rd, which would be this Friday. But if it's been taken down, who knows when we'll see these added.
