Trivia: In Revenge Of The Sith, General Grievous' first appearance was made notable by his rasping cough. In the Star Wars storyline, the crushing of his chest by Mace Windu in this episode was presented as the logical reason; but actually, George Lucas merely wanted to signify that Grievous is not a droid, but a cyborg.
Trivia: Among the Jedi there is a human Padawan, who is called Sha'a Gi Zonks in several sources. According to Clone Wars director Genndy Tartakovsky, the character was inspired by the character Shaggy Rogers from the Scooby-Doo cartoons, resulting in a similar appearance and name pronunciation. Also, Zoinks was a favorite quote of Shaggy's.
