The Coachelle system was a part of the Terr'skiar sector of the Kashyyyk Region, within the Slice portion of the Mid Rim. It constituted a part of the constellation that the inhabitants of the Outer Rim Territories' asteroid Oseon 6845 had named the Silly Rabbit, and it contained an asteroid belt as well as five planets, one of which was the terrestrial world Coachelle Prime.
The Ootmian Pabol hyperlane linked the Coachelle system to the Terr'skiar system and originally also connected it to the Ota system of the neighboring Mytaranor sector; however, after the destruction of the Kyyr system by a supernova in 4000 BBY, the resultant formation of the Thornhedge Pulsar and the Thornhedge Nebula severed the Coachelle–Ota segment of the hyperspace route. Afterward, Coachelle Prime became shrouded in the nebula's streamers of gas and dust. The system shared its name with Coachelle Automata, a droid manufacturing company that designed the LEP servant droid.
Coachelle Prime was the homeworld of the Lepi Jaxxon.
The Lepi, a sentient species native to Coachelle Prime who spoke the Lepese language, were known off-world by 3637 BBY. In response to overpopulation on Coachelle Prime, the Lepi invented the hyperdrive and went on to colonize all the other worlds in their star system as well as a large portion of its asteroid belt. That expansion appeared to have provided ample room for the spacefaring species, which had many starships left poorly guarded in the Coachelle system.
The Lepi future smuggler Jaxxon was born on Coachelle Prime. Longing to travel off-world, when he was twelve years old, Jaxxon stole away from his homeworld aboard a freighter, traveling to the Outer Rim Territories at some point by 21 BBY.
The Coachelle system was introduced in the article "The Starhoppers of Aduba-3," which was authored by Pablo Hidalgo with Cory J. Herndon and Michael Mikaelian for use with Wizards of the Coast's Star Wars Roleplaying Game and published in the fourth issue of the Star Wars Gamer magazine on June 19, 2001. The 2009 reference book The Essential Atlas placed the system in in grid square P-10.
The name of the Coachelle system was chosen as a reference to a line in the cartoon short "Bully for Bugs" by the character Bugs Bunny (pictured).
In 2006, Hidalgo confirmed that, given the character Jaxxon had originally been created as an homage to the Looney Tunes cartoon short character Bugs Bunny, the name of the Coachelle system had also been chosen in reference to that franchise. The Star Wars Gamer article contains the phrase "[…] having colonized all five worlds of the Coachelle system and the asteroid belt therein […]," which references Bugs Bunny's line from the 1953 short "Bully for Bugs:" "Pardon me, sir, but could you direct me to the shortest route to the Coachella Valley and the Big Carrot Festival… therein?"
