Tubby is a kindergarten student at Third Street School. The main duty in his kindergarten class is to chase big kids out from amongst them. The big kids have no trouble escaping him because he is so slow, hence his weight. He can produce the best burps at Third Street except for the brief time when Jared Smith, who could do everything better than everyone, moved there.
Tubby is very dedicated and has a strong sense of right and wrong. This is illustrated in "Kindergarten Derby" when Tubby expresses his wish to show everyone that fat people are just as good as skinny people. He decided that people would appreciate fat people if he could win the derby, and so he dedicated himself to training with the help of Mikey. While he was training, he noticed how the other kindergartners were being treated like horses by the big kids. In response to this terrible treatment and as a tribute to his trainer, Mikey (who had been the only kid in the history Third Street to not finish the race), Tubby's wish, as granted by King Bob for winning the derby, was to end the tradition of the Kindergarten derby.
Tubby is red-haired, overweight, and sports the savage look. When he was in first grade with Hector, he has neat combed hair and wears a yellow t-shirt, blue pants, and sneakers.
Tubby also expressed a very forgiving nature in the episode, "Here Comes Mr. Perfect" when he decided to forgive Jared Smith for out-burping him and break the lock-out on Jared that had been instigated by T.J. for Jared being better than everyone else. He proved to be a leader in this instance as everyone else in the school decided to follow suit and befriend Jared as well.
