All Grown Up! is an American animated television series developed by Kate Boutilier, Eryk Casemiro, and Monica Piper for Nickelodeon. It serves as a sequel to Rugrats, and explores the daily lives of protagonist Tommy Pickles, his little brother Dil and his childhood friends, now tweens/adolescents. The concept for the series was based on the Rugrats episode "All Growed Up", which served as the original 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 much of the surviving cast from the original series reprising their roles. Several episodes also feature flashbacks from the original series.
