In the initial episodes, Junior was as much a main character as Bob or Larry, having a starring role in at least one segment in every episode - even appearing alongside Bob in Josh and the Big Wall and [[wikipedia:Abe and the Amazing Promise] where he replaced Larry on the sink counter and interacted with the story's characters. As the series has evolved, his role has become less pronounced such that Esther... The Girl Who Became Queen would become the first episode in which Junior did not make an appearance. However, Junior continues to be featured prominently with leading roles in such movies as Lyle the Kindly Viking, The Wonderful Wizard of Ha's, and Lord of the Beans.
Junior is voiced by Lisa Vischer.
