Star Bunnies are characters in the Wii video games Super Mario Galaxy and Super Mario Galaxy 2. In Super Mario Galaxy, they are actually Lumas that transformed into bunnies. It is unknown if that also is true in Super Mario Galaxy 2. They first appear in the Gateway Galaxy in Super Mario Galaxy, and can be found in several levels later in the game. Their hobbies include telling Mario different tips and playing games, offering Mario Power Stars if can beat them. If they are encountered in Super Mario Galaxy 2, they will visit Starship Mario.
They appear as small white bunnies, with ears shaped like comets. Their ears could be the colors yellow, blue, purple or white. Their tail is often the same colors as their ears. According to Lubba, they are the cutest creatures in the galaxies.
