During one of these centennial visits to Mushroom World, the Comet Observatory was attacked by Bowser, who stole the observatory's Power Stars and Grand Stars. Rosalina later appeared to Mario/Luigi after Peach is kidnapped. In order to aid Mario/Luigi she gave him a Luma, the same one seen with Peach at the Star Festival. After Mario/Luigi collected enough stars to power the ship, Rosalina flew the observatory to the center of the universe for the final confrontation with Bowser.
Rosalina appears during the ending sequence of Super Mario Galaxy 2. Lubba reveals at this time that he and Rosalina had met before, but the details of their meeting remain unknown. Rosalina also frequently sends letters to the Baby Luma that's with Mario, but she does not reveal her identity in them.
When the player manages to get 120 Stars and beats the final boss again, a scene is shown, showing Rosalina and her Lumas in the Library, revealing that she was telling the story of Super Mario Galaxy 2. Then, she decides to narrate how Mario (and Luigi) collect every Green Star to her Lumas. If Mario and Luigi manage to collect every single star in the game, and survive the Grandmaster Galaxy Daredevil Comet run, Rosalina will thank and join the two on the Starship Mario.
Players can also use Rosalina to represent their file on the file select screen. However, the Rosalina avatar can only be used on save files in which the player has collected 120 stars, and unlocked the Green Star Prankster Comets.
