Tweek Tweak

Tweek Tweak is a fourth-grade student at South Park Elementary. He drinks lots of coffee, which is laced with meth, which causes paranoia and jittery muscle spasms. He made his first appearance in the Season Two episode, "Gnomes", where it focused around him and The Boys doing a class project together.
== Background ==
His next major appearance was in "Tweek vs. Craig" where he and Craig Tucker were pitted against each other in a fight by the other children for amusement. He was later brought into the main group from the Season Six episodes "Professor Chaos" to "Child Abduction is Not Funny". He is mostly used as a background character after leaving The Boys group in Season Six but continues to make frequent appearances and have speaking roles in the series from time to time. He is still in the extended group, Coon and Friends.
== Trivia ==
* His weight was mentioned as 48lbs in "Tweek vs. Craig".
* Tweek has been shown to pull his hair out of stress.
* Tweek goes to a "happy place" when he wants to calm down in "Free Hat".
* In the episode "Gnomes", his parents' coffee shop, Tweek Bros. Coffeehouse, went out of business because Harbuck sopened a branch in South Park, though his father was hired to manage Harbucks. However, Tweek Bros. Coffeehouse is mentioned later in the series nonetheless.
* Tweek seemed to practice fatalism in the episode "Free Hat".
* Tweek was worshiped as a deity by the "sea people" in the episode "The Simpsons Already Did It", though he was not pleased about it. All his followers were quickly killed in conflict with Cartman's followers.
* Tweek speaks fluent Mongolian, as do the other kids, which he puts to use when he talks to the Mongolian warriors he lives with for a short time in "Child Abduction is Not Funny".
* In the game South Park Let's Go Tower Defense Play!, Tweek was ejected from the group for not paying enough attention to the boys, and being overly nervous.
* Tweek is an unlockable character in South Park Let's Go Tower Defense Play. His special ability is running faster and killing anything that he runs into for five seconds.
* Tweek has not appeared in Mr. Garrison's class since "Breast Cancer Show Ever". He would later return in "The Pandemic Special".
* In later seasons, Tweek seems to have gotten better with his shaking and eye ticks.
* It is hinted that Tweek, along with his parents, are supposed methheads; during South Park: The Stick of Truth, he sends Douchebag to fetch "the package" from the McCormicks' meth lab and deliver it to Tweek Bros. Coffeehouse for mixing into the coffee. Richard Tweak takes a test lick of the meth after its delivery and mentions "it's good shit". This hints that the meth in the coffee is actually what causes his nervous, jittery condition.
* Despite claiming otherwise, Tweek appears to be a very good actor, as in "Tweek x Craig", he was able to convince the school that his "break-up" with Craig is genuine. For a second after his performance, he smiles, suggesting he thought he did well with his acting.
* Tweek appears slightly shorter than other students, as his legs show less than others. This could be referencing the popular belief that coffee stunts growth in children.
