The hungry Luma appears in Super Mario Galaxy from 2007 and its 2010 sequel, where feeding it Star Bits causes it to transform into a new planet or galaxy. The character's munching audio comes from Nintendo's in-game sound design, with music direction by Mahito Yokota. Clips of the sound began circulating on gaming soundboards and YouTube compilations as fans replayed the Galaxy titles. It remains popular because the Galaxy games are beloved Nintendo classics, and the short eating sound is instantly recognizable to Mario fans.
