Sy was voiced in the original version of "Jedi" by Lucasfilm sound engineer Annie Arbogast, who also wrote the Huttese-language lyrics to "Lapti Nek." The track was recorded at Lucasfilm's Sprocket Systems (currently Skywalker Sound), and was even the recipient of a 1983 Apex Award. For close-up shots, Sy's mouth was articulated using a nearly-invisible wire connected to a microphone stand. The puppet was replaced with a computer-generated image for the Special Edition rerelease. The CGI was spliced in with shots of the original puppet and created a continuity error with the puppet Sy's headdress feather appearing and disappearing during the film's first act.
