The Mooloolians were a tribe that was native to Janguine, a planet located in the Halthor sector of the Outer Rim Territories. They occupied the mountainous region of the planet, while a species of barbarians inhabited the jungle regions. The jungle barbarians eventually vanished, with the Mooloolian tribe absorbing their language by the year 275 BBY. In 25 ABY, the protocol droid C-3PO speculated that the language used by a newly encountered species, the Yuuzhan Vong, was related to the Janguine language; however, this later proved groundless.
