All Grown Up
All Grown Up is a Nickelodeon animated series based off of Rugrats. It has the same creators and same kids, and it debuted November 2003.
The show follows the Rugrats gang, no longer toddlers, but preteens! They have all changed quite a bit with interests, hobbies, and looks. They are all in Middle School and experiencing new stuff, though they still get in and out of trouble. At least they'll always have a new adventure ahead of them.
This show was inspired by the hour long pilot episode, All Grown Up that debuted in August 2001, which was to celebrate the Rugrats 10 Year Anniversary, which had the gang 10 years in the future. And starting with Season 2, the show got a makeover with animation and character style.
