Super Mario 3d world

[Derpywolfman111]

My brother and I got super Mario 3d world on the wii u. On the last world of story mode we heard about a space world with Roselina. We found the space world and beat all of the levels, but still no Roselina. How do I get her?

I did a research and on a certain forum it said : The second stage of this world needs to be beaten before Rosaline unlocks. You'll even get a nice message that you've done exactly that. I think it should unlock for you but here is the source :

Maybe this video will clarify something that you missed ?

First you have to beat World Bowser. You have to beat this world before doing anything else. Go to World Star. After beating World Bowser, you can access this world by going into the Rocket that appears in World 1. Beat World Star-1, Rainbow Run. You'll encounter rainbow-colored platforms, as well as having to light up a sprite of Link as he appears in the original Legend of Zelda game. After beating the level, you'll be able to access World Star-2. Beat World Star-2, Super Galaxy. This level is based off of the levels seen in the Super Mario Galaxy games. After beating this level, you'll unlock Rosalina as a playable character.
