NOM-NOM is a planet located in the farthest region of the binary star system. This planet is inhabited by the Noms. The docile creatures resemble domesticated cats with the sleek body of the cheetah. This formerly jungle-like planet contained many flowing bodies of water and a vast amount of lush vegetation was razed and destroyed by terrorist space otters (AKA Oms) who turned the planet into a barren desert.
Nom: NOM-NOM used to be awesome until those damn otters came here.
