 This was the last season of Adventure Time to feature Nick Jennings as the series'art director; he had originally been brought on at the start of the first season at the behest of Cartoon Network, and had served as the sole art director for five and a half seasons. Following the show's sixth season, he left to work on the 2016 reboot of the Powerpuff Girls. He was replaced by Sandra Lee — also known as Sandra Calleros — who had previously been the series' background paint supervisor. Both Jennings and Lee were credited as co-art directors starting with the thirty-third episode, "Jermaine".
