The Twi'lek Purge was result of Darth Elmo, the Twi'lek intolerant boss of Sesame Street, who had just about enough of his sneezing and throwing up all over the place. After not a lot of consideration, he decided that he couldn't take the Twi'leks anymore, and all of them had to be destroyed. However, his employer Darth Darth Binks was rather fond of Twi'leks and did not sanction this attack. Elmo ignored him, tough, and dispatched his main enforcer, Darth Animal, to Ryloth, the Twi'lek homeworld. If anything, he could just tell Darth Darth Binks that Darth Animal had acted on his own, completely disregarding Darth Darth Binks' commands. In the end, Sesame Street was victorious. When asked about what had happened to the Twi'leks, Darth Elmo told Binks that Animal had acted on his own. Soon after, Darth Animal was killed by Binks...or so he thought. Animal secretly made his way back to Elmo, after being presumed dead and took the title of Sith Underlord.
