The Inyusu-class Star Yacht represented a specific yacht design, produced by the SoroSuub Corporation. This particular class was envisioned as a compact, individualized transport, and the Inyusu-class offered a flexible internal configuration to satisfy each buyer's specific needs. Nien Nunb, a Sullustan smuggler who joined the Rebel Alliance, possessed a significantly altered Inyusu-class vessel known as the Mellcrawler. Unfortunately, this ship was destroyed on the Star Destroyer Shieldmaiden during the events of Operation Yellow Moon. Subsequently, Nunb obtained and customized another Inyusu-class Star Yacht, which he named the Mellcrawler II.
