CB-3DU

CB-3DU was a protocol droid who served as a teacher on the planet Nevarro following its liberation from the forces of the Imperial remnant led by Moff Gideon. As the protocol droid was teaching a class on astrography, the infant Grogu, who was under the protection of the Mandalorian Din Djarin, was left in the room by Magistrate Greef Karga to keep him safe while Djarin assisted Karga in destroying the remaining Imperial base on Nevarro. Grogu was later returned to Djarin upon the latter's arrival at the class.
