Rosalina's Story

Rosalina's Storybook is a book in Super Mario Galaxy. It is the story of how Rosalina made it into space and how she became the "mother" of Lumas. In the Comet Observatory's Library, Rosalina sometimes reads from her storybook to her Lumas. Mario can come in to listen to the story. Each time, she will only read one chapter. In all, there are nine chapters to read from.

Yoshiaki Koizumi, director of Super Mario Galaxy, was the writer of the storybook. He wrote the script of it, late at night, when no one was around so no one found out about it. The next day, he told Shigeru Miyamoto about the story and presented it to him. Miyamoto was surprised that Yoshiaki wrote the script late at night with nobody around. Yoshiaki Koizumi, in Nintendo Power, mentions that he would enjoy Rosalina's Storybook to get published into a Children's Book. He also mentions that someone at Nintendo has actually done a book of the storybook, but has only made one copy for himself.

Story
Rosalina's story begins when she was a young girl living on Mushroom World. One day, Rosalina discovered a rusty spaceship (resembling the Starshroom) with a Luma inside. The Luma introduced itself, revealing that it was waiting for its "Mama". Rosalina bonded with the Luma, and promised that she would wait with it. Armed with her father's telescope, Rosalina stargazed for years, searching for the comet that carried the Luma's mother. Fearing it was taking too long, Rosalina and Luma fixed the spaceship then set off into space. Traversing through asteroids, Rosalina grew very hungry. She had brought essentials for the trip: the telescope, food, her stuffed bunny (resembling a Star Bunny) and tea, but forgot water. At the sight of a pouting Rosalina, the Luma then told her that Star Bits would be all she needed, and began to share them with her. Leaning out the spaceship the two collected Star Bits to eat.

One night a shimmering comet made of ice flew past the ship. Hoping Luma's mama would be there, the two set foot onto it. Mama was nowhere to be found, but discovered Star Bits clustered to the south.

One night in a dream, Rosalina remembered her mother. Rosalina's mother greatly resembled how she herself would come to look. In the dream Rosalina's mother was going away. She told her not to worry, because she would always be watching her. Clinging to her mother, Rosalina cried. Upon waking up, Luma noticed tears coming from Rosalina's eyes (and mistook them for Star Bits). However, Rosalina explained what they actually were. She was crying because she would never see her mother again. At this, they both broke down into tears over their lost mothers.

Continuing the search, Rosalina comforted the Luma, and told the little star she would take care of it, and with that a spark in her heart went off. She became determined to mother the Luma and then started to make the home out of the comet. With tools found inside the comet, Rosalina built what would become Domes that would link to various galaxies. For now, however, it was a shelter for Luma. Once completed it seemed very large for her and just one Luma.

One day another comet flew close to Rosalina's new home, and from the comet another Luma appeared. The Luma affectionately called out and said Rosalina was it's "Mama." Soon the other Luma joined in: "My Mama, My Mama!" Rosalina found this so touching she couldn't help but laugh. Out of the comet many more Luma came, and all of them called her Mama. She took them all under her wing, named them, and moved them all into her newly built house on the comet.

One night Rosalina remembered her home planet of Mushroom World, and wondered if everything was all right there. She looked through her telescope until she could make out the planet's surface. She found her favorite spot for stargazing, on top of a hill with a lone tree, and it reminded her of her family. She wanted to go home, but she knew she'd never see her mother again. At this time it was revealed her mother had died, and was buried under the tree in view. Rosalina had been aware of this all along, but was unwilling to truly believe it.

The Luma comforted the crying Rosalina, assuring her that she shouldn't be sad. They told Rosalina that her mother is a part of her and will always be close by. It was at this time the Luma she met inside the ship had an idea. The Luma transformed the comet into the Comet Observatory to help in finding all their Mamas. The Luma explained that when they grow up, they transform into various things, including stars, comets, and planets. Rosalina was so overcome with emotion due to this selfless act she thanked all the Luma that had huddled around to hug her. From that day on Rosalina never cried again.

The observatory grew and grew into a better home, and Rosalina and the Luma were proud to call it their own. At a welcoming party for a new Luma, Rosalina and the others baked a cake topped off with Star Bits. Coming together in such a way made her realize the Luma were her new family, and she was determined to raise them and help them all fulfill their destinies. It was at this time she began to call herself the mother of the Luma.

Rosalina was reminded yet again of her home one night. Even though she had a new goal in her life, she thought it'd be nice to visit her favorite spot from her past. So every one hundred years the Comet Observatory passes over the Mushroom Kingdom so that she can re-visit her homeworld.

During the story, Rosalina mentions her home planet as "a blue planet", the Earth is also known by this name, so it is possible Rosalina comes from the Earth.
