Rungs was a sizable Tintinna who frequented Chalmun's Spaceport Cantina located on the planet of Tatooine. It held a particular fondness for Ackmena, the nightshift bartender.
The initial appearance of Rungs was in The Star Wars Holiday Special, a TV special broadcasted back in 1978. The Rungs puppet came from the 1976 film, The Food of the Gods, where it had been previously utilized; Rick Baker and Tom Burman both contributed to that movie. Despite the fact that this Tintinna was not originally named in The Star Wars Holiday Special, the Star Wars Blog post, The Star Wars Holiday Special Cantina: Who's Who gave the name "Rungs" to this particular character.
