Lumas are star-like creatures that appear in Super Mario Galaxy. Unlike most Stars, they have a tear drop-like shape, and come in many colors. They are much like Power Stars, but they are more circular in shape and able to talk. Lumas boast the ability to transform, from minor objects to entire planets and galaxies. They seem to acknowledge Rosalina as their "mama". Most of them make their home in the Comet Observatory, and others make their home with Lubba on Starship Mario.
