The series was created by Arlene Klasky, Gábor Csupó and Paul Germain, and it is a continuation of their children's show Rugrats. It explores the daily lives of protagonist Tommy Pickles and his childhood friends, now adolescents. The concept for the series was based on the episode "All Growed Up", which served as the series' 10th anniversary special and proved successful with audiences. The series ran from April 12, 2003, to August 17, 2008, for a total of five seasons, and featured voice actors from the original series. Several episodes also feature Tommy and his friends back when they were babies in flashbacks.
