Ongachic

The Ongachic are an alien race. The Yeerks once infested and enslaved them, but they fled their home planet to become a nomadic, space-faring race. The Yeerks gave up on them because they were too spread out through the galaxy to ever find and infest.

Culture and society
Some Ongachic serve as minstrels, traveling throughout the galaxy to different planets and playing music in exchange for their stay.
