From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Planet Conuts (小夏 惑星, Konatsu Wakusei; FUNimation "Planet Konats"; Literally meaning "Small Summer Planet") is a planet in the Southern Galaxy.
Planet Conuts' Japanese name is a pun on the word Kokonattsu, or Coconut in English.
About one thousand years before the events of Dragon Ball Z, Planet Conuts was attacked by Hirudegarn, a monster once thought to have been killed by "ancient" Konatsians, sparking a war on the planet. What became of the planet after the Hirudegarn war is unknown.
