Adventure Time season 6

The sixth season of Adventure Time, an American animated television series created by Pendleton Ward, premiered on Cartoon Network on April 21, 2014 and concluded on June 5, 2015, and was produced by Frederator Studios and Cartoon Network Studios. The season follows the adventures of Finn, a human boy, and his best friend and adoptive brother Jake, a dog with magical powers to change shape and size at will. Finn and Jake live in the post-apocalyptic Land of Ooo, where they interact with the other main characters of the show: Princess Bubblegum, The Ice King, Marceline the Vampire Queen, Lumpy Space Princess, BMO, and Flame Princess.

The season was storyboarded and written by Andy Ristaino, Cole Sanchez, Tom Herpich, Steve Wolfhard, Seo Kim, Somvilay Xayaphone, Graham Falk, Derek Ballard, Jesse Moynihan, Masaaki Yuasa, Adam Muto, Kent Osborne, Lyle Partridge, Bert Youn, Madeleine Flores, Jillian Tamaki, Sam Alden, Sloane Leong, Brandon Graham, and David Ferguson. The season also featured Yuasa and Ferguson as guest animators for the episodes "Food Chain" and "Water Park Prank", respectively. This season was the last to feature Sanchez and Ristaino as storyboard artists; the former took a directing job on the mini-series Long Live the Royals (although he eventually returned to the series as a supervising director for its eighth season), and the latter became an Adventure Time background designer.

The season premiered with two episodes, "Wake Up" and "Escape from the Citadel", which together were viewed by 3.32 million viewers. This marked a significant increase in ratings from the previous season finale. The season concluded with the two-part finale "Hot Diggity Doom" and "The Comet", which was viewed by 1.55 million viewers. Beginning with this season, Adventure Time moved from its long-held Monday timeslot, with many episodes instead airing on Thursdays. A number of sixth-season episodes also aired internationally before they were broadcast domestically. The season was met with largely positive critical reception. The episode "Food Chain" was nominated for several Annie Awards, as well as an Annecy International Animated Film Festival Award. The episode "Jake the Brick" won a Primetime Emmy Award for Short-format Animation at the 67th Primetime Emmy Awards, and Tom Herpich won an Emmy for his work on "Walnuts & Rain". Furthermore, "The Diary" and "Walnuts and Rain" were nominated for Annie Awards, and the show itself won a Peabody Award. In addition, several compilation DVDs that contain episodes from the season have been released. The full season was released on DVD and Blu-ray on October 11, 2016.

Concept
The season follows the adventures of Finn the Human, a human boy, and his best friend Jake, a dog with magical powers to change shape, grow, and shrink at will. Finn and Jake live in the post-apocalyptic Land of Ooo, wherein they interact with the other major characters, including: Princess Bubblegum, The Ice King, Marceline the Vampire Queen, Lumpy Space Princess, BMO, and Flame Princess. Common storylines revolve around Finn and Jake discovering strange creatures, dealing with the antagonistic but misunderstood Ice King, and battling monsters in order to help others. This season's main story arc, however, deals with Finn discovering the true identity of his human father, and his subsequent attempts to reconnect with him. The season ends with Princess Bubblegum being deposed by the King of Ooo (voiced by Andy Daly), and Finn fighting the primordial cosmic space demon Orgalorg (the actual identity of Gunter the penguin).

Production
On January 28, 2013, during the middle of the show's fifth season, Cartoon Network officially announced that the show had been renewed for a sixth season. In July 2013, storyboard artist Jesse Moynihan revealed that production for the sixth season had begun. This season's episodes were produced in a process similar to those of the previous seasons' episodes. Each episode was outlined in two-to-three pages that contained the necessary plot information. These outlines were then handed to storyboard artists, who created full storyboards. Design and coloring were done at Cartoon Network Studios in Burbank, California, and animation was handled overseas in South Korea by Rough Draft Korea and Saerom Animation. While almost all of the animation for the show is done through these studios, two episodes were written and animated entirely by guest animators. The first, "Food Chain", was helmed by noted Japanese animator Masaaki Yuasa, and was entirely animated by Yuasa's own studio. The second, "Water Park Prank", was directed by David Ferguson.

The season was storyboarded and written by Andy Ristaino, Cole Sanchez, Tom Herpich, Steve Wolfhard, Seo Kim, Somvilay Xayaphone, Graham Falk, Derek Ballard, Moynihan, Yuasa, Adam Muto, Kent Osborne, Lyle Partridge, Bert Youn, Madeleine Flores, Jillian Tamaki, Sam Alden, Sloane Leong, Brandon Graham, and David Ferguson. "The Prince Who Wanted Everything" marked the return of Youn—a storyboarder during the show's first, third, and fourth seasons—to the series. He had left after the first season for mandatory military service in his native South Korea, and returned during the third season. He once again left the series after the conclusion of its fourth season to focus his attention on Studio Spiyo in Seoul, South Korea. However, Youn returned to work on "The Prince Who Wanted Everything", although it was a "one-off gig", and he subsequently took a job working on Over the Garden Wall. The sixth season of Adventure Time also marked the final season that both Andy Ristaino and Cole Sanchez worked as storyboard artists. Ristaino revealed in a podcast that, once the season was finished, he was "burnt out". He did, however, return as a background designer for the seventh season. Sanchez, on the other hand, left the series to become a supervising director on Long Live the Royals. He eventually returned to the series as a supervising director for its eighth season.

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 art co-directors starting with the thirty-third episode, "Jermaine".

Finn's father, Martin, first introduced in "Escape from the Citadel", is voiced by Stephen Root. The Adventure Time cast records their lines together as opposed to doing it individually. This is to capture more natural sounding dialogue among the characters. Hynden Walch has described these group session as akin to "doing a play reading—a really, really out there play."

Reviews and accolades
The season received largely positive critical reviews. Eric Kohn of IndieWire applauded the two-part season opener, "Wake Up" and "Escape from the Citadel", for taking a darker turn in regards to the series' storytelling. Furthermore, he noted that the storyline concerning "Finn's cursed sword arm—an ingredient that has festered in the sidelines for weeks—reaches a beguiling new state." Likewise, Oliver Sava of The A.V. Club complimented the episodes for being full of harsh realizations concerning Finn's father and the vulnerability of his body; he ultimately concluded that "the developments of these two episodes dramatically alter the series' status quo to give this season an added boost of momentum from the very beginning." Each episode was also graded by The A.V. Club with a different letter grade; the season received two C's, twenty-two B's, and seventeen A's.

The A.V. Club named the series the 27th best television series of 2014, noting that, "The ongoing sixth season has ventured into even more dangerous emotional territory: parenthood. Coupled with deep dives into the history of Ooo and the increasing visual confidence of episodes like the surreal, breathtaking 'Food Chain,' Adventure Time appears ready to use its considerable heft and years of laying narrative foundations to do some of TV's finest storytelling about grappling with the past and accepting the responsibilities of adulthood." The site selected "Food Chain" and "Breezy" as stand-out episodes from 2014, and it later named the season finale "The Comet" one of the best TV episodes of 2015.
