Clarence's New Adventures

The fourth season of the animated children's slice-of-life series Clarence aired on Cartoon Network from September 16, 2018 to March 23, 2020, and consisted of thirteen episodes, having to be the first season to have less episodes. The fifth and sixth seasons consists of the same number of episodes.

Clarence has concluded a few months on the same year with its third season, but was given a revival by On The Way creator, Xavier Mosley, who demanded to have the show continue with three more seasons.

The season features a half-hour crossover with Steven Universe entitled "Clarence's Universe". Guest stars are also featured throughout the season; T.J. Miller, Emma Stone, Chris Hardwick, Seann William Scott, and Ed Sheeran.

During this season, Amy Gillis returns to Aberdale ("Clarence's Universe"), Chad and Mary compete with their new neighbors ("The New Neighbors"), Breehn gets a brother ("Brother Breehn"), a glimpse at Mary and Chad fell in love ("Back Then"), and Clarence and Jeff switch schools to West Aberdale Elementary ("Clarence and Jeff Go West").

The season is followed by a feature film released three months after the finale.

Production
Mosley had the idea of a crossover between Steven Universe and Clarence ever since late 2014. He previously had it to be the season premiere, but decided to push it five episodes back, with Principal Reese taking its place.

The episode where Clarence and Jeff get sent to West Aberdale Elementary was chosen to be the final episode of the season.

Casting
As Mosley took over as the showrunner on the series, he brought back Skyler Page as the voice of Clarence, and as the new voice of Chad in the forth season and onward. Spencer Rothbell became the current voice of Nathan. He even recast Amy Gillis' voice actress from Ava Acres to Ariel Winter, as he and Winter had previously worked on the On The Way franchise together. He even made the episode list to have thirteen episodes per season.

Animation
Saerom Animation is not involved with the revival. Instead, Sugarcube Animation provides the animation for the fourth season and so on.
