I found a website (http://www.niennunb.8k.com/) dedicated to everyone's favorite
Sullustan pilot. It has some backstory, but be warned that this might be made up for all I know. Apparently the planet
Sullust is covered with toxic gasses and the inhabitants live in a huge network of caverns. They develop an innate sense of direction, which makes them skilled pilots and navigators. The planet is ruled by the
SoroSuub corporation, makers of fine high tech goods. SoroSuub sided with the Empire until the population rebelled, led by Nien Nunb.
The web site also has a
.wav file of
every line uttered by him in
Return of the Jedi:
Abdedu hudiama mudiama mookeya, hah?
Ungueto, puepe tu nu nit.
De muiti bitu deyamo biuti.
Uh, muteguto, huy.
Whoa!!!
"the infamous laugh"
De dedo du.
Cool, in obsessive sort of way, eh?
