King Bob is the uni browed current ruler of the Third Street playground and the former prankster prince, whose throne sits atop the jungle gym. He is one of the school's older students (he is in the sixth grade)11-year-old boy. Bob is regularly depicted with a number "8" hockey jersey, and carries a hockey stick as a scepter. He rules fairly in the hopes of being remembered when he has left the school, though does occasionally take things too far, such as building a pyramid by forcing the playground to build it, but later has to apologize to those he wronged. He is said to be a sixth grader, though he appears in T.J.'s class in at least one episode.
