Squeak, a messenger of the Tintinna variety (also known as Tin-Tin Dwarfs), was employed by Big Bunji. In Mos Eisley, on the same day that Han Solo and Chewbacca were scheduled to carry Luke Skywalker along with Obi-Wan Kenobi to Alderaan, Squeak encountered the smuggler with a proposition to sell him a shipment of chak-root.
