ChiEta Galaxy

The ChiEta Galaxy is the galaxy where the PikSystem and the Louie System are located, and by extension, Hocotate and the Pikmin Planet. It is a huge (even by galaxy standards) starburst galaxy.

Trivia

 * Starburst galaxies actually exist in real life.
 * The name: 'ChiEta' is a portmanteau of the Greek letter translations: 'Chi' and 'Eta'.
