The heyblibber was a model of submarine used by the Gungans. Boss Rugor Nass, the leader of the Gungan High Council, owned a heyblibber until Jar Jar Binks crashed the prized submarine, after which Nass ejected the clusmy Gungan from Otoh Gunga and enacted the "nocombackie law," which threatened Binks with pain of being pounded to death should he ever return.
