Tweek is another one of the boys' classmates. He was first shown and introduced in the Season 2 episode, "
Gnomes," where he continually witnessed small creatures steal his underwear. He was also featured several times in Season 6 as one of Kenny's replacements. Tweek is always nervous and scared of everything. He shakes a lot, though that may be due to the large quantities of coffee his parents serve him.
