The students are a parody of humans from late-20th century cartoons, and their designs reflect and exaggerate this fact. They are flat humanoids resembling cardboard cutouts that are frozen in a position of excitement: arms raised, smiles on their faces. They cannot move their limbs, and thus have to swing their whole bodies about to move.
While at first the students appear to be simple, stereotypical caricatures: carefree, excited, incapable of any negative emotion, a more sinister side to them is displayed in "The Extras." When one of them manages to move his limbs and becomes a full human, the other students attack him for his differences. This shows that the students can be cruel and prejudiced.
- "The Sweaters": Their debut. They spectate the tennis match between Gumball, Darwin, Carlton, and Troy.
- "The Extras": Two of them are major characters. One of them figures out how to move his limbs and thus is attacked by his peers. He and a friend escape in a car.
