The heyblibber represented a specific submarine design utilized by the Gungans. Rugor Nass, who held the position of Boss and led the Gungan High Council, possessed a heyblibber until Jar Jar Binks caused an accident involving the valuable submarine; following this incident, Nass expelled the awkward Gungan from Otoh Gunga and implemented the "nocombackie law," a decree that warned Binks that he would face being pounded to death if he were to ever come back.
