Lumas

Lumas are star-like creatures that inhabit outer space. They are the adoptive children of Rosalina and many of them make their home in the Comet Observatory.

Characteristic Traits
Unlike most stars, Lumas have a rain drop-like shape and come in many colors, with the most common one being yellow. They are much like Power Stars, but are more circular and have the ability to talk. The Lumas are each very friendly and assisted Mario during his quest. Lumas have the ability to transform, from minor planetoids to entire galaxies, and according to Rosalina, some Lumas can even transform into Power Stars.
