wrote and directed the episode. "Food Chain" was written, storyboarded, and directed by noted Japanese animator
Masaaki Yuasa, with Yuasa's longtime associate
Eunyoung Choi serving as the episode's creative director. The entirety of the episode was animated by
Science SARU, Yuasa and Choi's Tokyo-based studio. In an interview with
The Mary Sue,
Kent Osborne, head of story for
Adventure Time, revealed how the episode came to be. After
Adventure Time had become a mainstream success,
Cartoon Network allowed the show's producers to experiment with guest animators and directors. The first episode to be entirely helmed by someone new was
season five's "
A Glitch Is a Glitch", animated by
David OReilly. After the series was renewed for a sixth season, the network agreed to let the producers approach Yuasa. Once asked, Yuasa agreed to work on the episode, and he traveled to Los Angeles, where he pitched his ideas about an episode centered entirely around the concept of the food chain, using "big beautiful watercolor illustrations" to express his ideas. The episode also guest stars
Regular Show storyboard artist Minty Lewis as the caterpillar Erin. Lewis has had limited experience with voice acting (she plays the role of Eileen on
Regular Show), but in an interview with
Newsarama, she expressed her surprise at being asked to voice a character for "Food Chain": "Having never done any voice acting besides
Regular Show, I was very surprised to get a call asking me to do a voice on
Adventure Time." == Reception ==
