Moon-yos, which can also be written as moonyos, were beings that lived on a far-off island known as Pabu. The island's elderly population stated that moon-yos were living on Pabu prior to the arrival of people.
In approximately 18 BBY, some moon-yos were playing in front of the residence of Shep Hazard, the mayor, when they felt the ground shaking beneath the island. This event frightened them and they scattered, because the tremors resulted in a large wave.
