Udjudg
A pair of Zybahhod Yenyoni are depicted, with one of them holding a special udjudg. The Zybahhod Yenyoni played a unique musical instrument known as the udjudg. Their "Y"-shaped naso-facial openings made them particularly well-equipped for playing this instrument.
Production Notes
Jennifer Kay, a Star Wars enthusiast, invented the udjudg for the backstory of her Zybahhod Yenyoni submission to the Design An Alien competition featured in the Star Wars Galaxy Magazines.
