Tubby

Tubby a kindergarten student at Third Street School. His 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.
