CZ-3
this Serv-O-Droid communications droid was present in Mos Eisley when Luke Skywalker sold his landspeeder to pay Han Solo for passage to Alderaan, shortly before the Battle of Yavin. CZ-3 was a white, humanoid droid that had been owned by Jabba the Hutt. CZ-3 had been used to store the Hutt's accounting data, but was stolen from Jabba's townhouse by Opun Mcgrrrr. This was part of Jabba's plan, however, as he had placed a transceiver rig inside the droid's head, allowing the Hutt to record a great deal of Mcgrrrr's criminal doings.
