Rudy Tabootie was originally eight-years-old in the first two Oh Yeah! Cartoons. When plans for a television series based on the shorts came around during production of the second season of Oh Yeah! Cartoons (1998), Nickelodeon executives insisted the creators age Rudy up to two years and to add a female protagonist, who became Penny Sanchez.
Bill Burnett didn't know that Elizabeth Daily and Candi Milo were singers until after he cast them for Rudy and Snap.
This show began as a recurring segment on Nickelodeon's Oh Yeah! Cartoons (1998).
Season one, episode one, "Rudy's First Adventure/Rudy's Story/Bushel Full of Yum" originally premiered as a sneak peak for the series on December 31, 1999, which would have been followed by a planned Fall 2000 release for the first season of the series. For unknown reasons, Nickelodeon delayed releasing the season until March 2002.
Rudy Tabootie's father Joe was based on Series Creator Bill Burnett's own father, who was also a butcher.
