Arlene Klasky, Gábor Csupó, and Paul Germain created the Nickelodeon animated television series Rugrats. The show centers on a group of toddlers—Tommy, Chuckie, Angelica, and twins Phil and Lil—and their daily lives, which frequently involve life experiences that turn into far larger adventures in the main characters' imaginations. The Rugrats frequently escaped adult control and went on excursions that contrasted the realism of their situation with the magical perspective of the toddlers. Rugrats was notable for teaching viewers about many ethnic and religious traditions, including the Pickles family's Jewish faith, among other life lessons.

During its 13-year career, Rugrats won over 20 awards, including four Daytime Emmys, six Kids' Choice Awards, and a star on the Hollywood Walk of Fame. From 1995 through 2001, the sitcom was a rating success, anchoring Nickelodeon as the network's top-rated show. Until SpongeBob SquarePants broadcast its 173rd episode in 2012, it was Nickelodeon's longest-running cartoon.

Joe Murray created the American animated television series Rocko's Modern Life for Nickelodeon. Rocko, an anthropomorphic Australian immigrant wallaby, and his friends, the eccentric steer Heffer Wolfe, the neurotic turtle Filburt, and Rocko's devoted dog Spunky, star in the series. It takes place in O-Town, a fictitious town.

The network gave the writers a lot of creative flexibility, and they could write for both kids and adults. So Rocko's Modern Life was criticized during (and after) its run for its perceived adult comedy, which frequently used innuendo and sarcasm. The show ran for four seasons and 52 episodes, beginning on September 18, 1993, and ending on November 24, 1996. On August 9, 2019, Netflix published a digital special titled Rocko's Modern Life: Static Cling.

With a bizarre concept based on the commonly held assumption that cats and dogs are natural adversaries, CatDog imagined the two being united as brothers. CatDog followed the sibling's Cat and Dog as they navigated life together, complicated by their very different personalities, and saw them face several challenges as a result of their conflicting viewpoints. Despite this, as well as Cat's propensity for deception and Dog's higher reputation in their community, they remain close friends.
