Adventure Time

In the United States, the series is rated TV-PG; Ward said he never wanted to push the boundaries of the PG rating, noting in an interview with Art of the Title that he "never really even thought about the rating ... we don't like stuff that's overly gross.

One game that was often used is called exquisite corpse, which one writer starts a story on a sheet of paper, and another writer tries to finish it.

Former storyboard artist and creative director Cole Sanchez said episode scripts are either created by expanding the good ideas produced by these writing games, or are based on an idea proposed by a storyboard artist in the hope it can be developed into an episode.

While many cartoons are based on script pitches to network executives, Cartoon Network allowed Adventure Time to "build their own teams organically" and communicate using storyboards and animatics.

The storyboard artists generally worked on an episode in pairs, independent from other storyboarders, which, according to freelance writer David Perlmutter in his book America Toons In, countered creative ennui and prevented episodes from being "alike in either content or tone".

The artists were then given another week to implement the notes and to clean up the episode.
