ZZ-4Z (ZeeZee)
Han's housecleaning droid on Nar Shaddaa, Zee-Zee was a JV-Z1/D gentlebeing droid manufactured by Serv-O-Droid. Zee-Zee was first placed in service to one of the Deans of the Spacers Academy. He was willed to the next 17 deans, and picked up quite a large body of embarrassing trivia on all of them. One of the Deans was Horace Wyrmyr, who didn't particularly like droids. Zee-Zee later provided Mako Spince with the codes to the physics lab from which he stole the antimatter he used to destroy the Academy's mascot moon. Wyrmyr, upon learning that Zee-Zee had leaked his secret codes, ordered the droid recycled. After he was expelled, Mako recovered Zee-Zee, but he eventually lost the droid to Han Solo in a sabacc game. Han didn't know what to do with the droid, but kept it as a way of keeping his small apartment clean. ZeeZee was a bit eccentric, and basically did exactly what Han told her to do. When he left Nar Shaddaa after winning the Millennium Falcon from Lando Calrissian, Han asked Zee-Zee to keep the place as it was when he left. The old droid did exactly that for many years, not allowing one, single, misplaced item to be returned to its proper place. Nothing was cleaned up, but was left as it was when Han left.
