Will Rosalina appear in Super Mario Galaxy 2?

Answer 1

If you get the game, don't be disappointed! I liked the Comet Observatory and Rosalina too, and the game is nothing without them, but they only appear in the game after you defeat Bowser. It's not the same feeling without them, is it?!

Answer 2

I have heard that she comes in the final galaxy of Super Mario Galaxy 2. Also, If you die about 4 or 5 times, her cosmic comet or shadow of her will come and complete the course for you but you will earn a bronze star instead of the real gold star. However, if you think you can do the course later you can come back and get the gold star but if you still can't the shadow can't be reversed from the galaxy so she will always be there.
