The more “kiddie” and simplistic episodes of Clone Wars (like Malevolence and the Jar-Jar episodes) are in-universe Republic propaganda films, which is why the Republic’s corruption is glossed over and the Separatists are shown as incompetent morons. The more mature and complex episodes (like Umbara and Ahsoka leaving the Jedi) are the actual truth of what happened.
Taking a que from Robot Chicken, Boba was insanely drunk on Malastarian gargle-blasters during the sail barge battle, which is why he was stumbling around in an almost intoxicated way while trying to fight Luke. His pain and suffering as the Tuskens dragged his acid-scarred body through the Dune Sea was accompanied by the worst hangover of his life.
Jar Jar is a dark side user, although he isn’t a Sith. He was banished from his tribe for discovering ancient Sith texts hidden in Naboo’s Sacred Place, and he used the knowledge contained in those texts to obtain vast dark side power. His signature technique was a subtle form of mind control, manifesting through apparent coincidence. When the Queen’s ship made it to Coruscant, Palpatine sensed Jar Jar’s power, and formed an alliance with him. Jar Jar would mind control the Senate into giving Palpatine absolute power, and in return Palpatine would have Jar Jar be one of his top advisors. However, this deal was a ruse, and Palpatine killed Jar Jar soon after the rise of the Empire.
