Tweek is an over-caffeinated, ADD-crazed 4th grader. His parents own the local coffee shop, which is especially helpful since he drinks coffee to calm down.
In Gnomes, Tweek and the The Boys have to do an assignment together. Tweek tells them that Underpants Gnomes steal his underwear at night. He later returns in Tweek vs. Craig in which he fights local trouble-maker Craig Tucker who later becomes his boyfriend in Tweek x Craig. When Kenny dies he becomes a replacement friend for about 5 episodes.
Tweek can be seen with a pet parrot in his room. Next time you see his room there is no sign of a parrot.
