The series drew inspiration from a variety of sources, including the fantasy role-playing game Dungeons & Dragons and video games. It was produced using hand-drawn animation; action and dialogue for episodes are decided by storyboarding artists. Because each episode took roughly eight to nine months to complete, multiple episodes were worked on concurrently. The cast members recorded their lines in group recordings, and the series regularly employed guest actors for minor and recurring characters. Each episode runs for about eleven minutes; pairs of episodes are often telecast to fill half-hour program slots. On September 29, 2016, it was announced that the series would conclude in 2018, after the airing of its tenth season. The series finale aired on September 3, 2018.
The series aired on Boomerang from June 2, 2018 to February 3, 2019.
