Nizuc was the manager for Jabba's entertainment. He booked the bands, and he tended bar on the Sail Barge. He was also his best customer, as some of the stuff he witnessed seriously drove him to drink. I mean, have you ever seen how Hermi Odle eats a sandwich? Disgusting.
Nizuc was in a drunken stupor when Luke blew him up on the Sail Barge.
