What is the name of the Rugrats spin-off with the characters as teenagers?

The Rugrats spin-off featuring the characters as teenagers is called All Grown Up!.

The series developed from the 2001 Rugrats special “All Growed Up,” which imagined Tommy Pickles, Chuckie Finster, Angelica, Kimi, and their friends ten years older. The special was created for Rugrats’ tenth anniversary and attracted such strong ratings that Nickelodeon commissioned a regular sequel series.

All Grown Up! premiered on April 12, 2003. Instead of focusing on toddlers interpreting the adult world, it followed the characters as tweens and adolescents dealing with school, friendships, family tensions, crushes, and other growing-up problems. The format also shifted toward longer, single-story episodes.

The title is often confused with “All Growed Up,” but that phrase names the original anniversary special and pilot concept. All Grown Up! is the name of the continuing spin-off. It ran for five seasons and 55 episodes, ending in 2008.
