Season 5: 2012-2014

In an interview with Charlie Jane Anders, Pendleton Ward revealed that the writers were working on season 5. Season 5 began with the airing of a two-parter on Monday November 12, 7:30 p.m. (ET/PT), 2012, on Cartoon Network titled "Finn the Human"/"Jake the Dog." The episode titles and production codes were revealed by the Frederator blog. It was also revealed that this season was to contain a one-hour special (with the production codes 1014-125, 1014-126, 1014-127, and 1014-128), but it was pushed off for later, and eventually cancelled. As of June 30, 2013, storyboarder Jesse Moynihan revealed that the one-hour "movie" was intended to divide season 5 in half, which has now been extended by another 26 episodes. On November 26, 2013, Jesse Moynihan announced on Twitter that the special had been scrapped.  This season consists of twice as many episodes as a normal season, making it the longest season so far. According to iTunes' synopsis, season 5.2 "heats up, cools down, then heats back up again as Flame Princess battles Ice King in a mathematical battle of the elements! And what will Princess Bubblegum discover in the aftermath?! Then P-Bubs joins Marceline on a top-secret mission in search of…wait…that’s top secret! Nice try!! Then take a trip with Finn and Jake to the birthplace of BMO. It will be so cool. But also hot."

Adventure Time was confirmed for another season (known as "Season 9" by the time) by Kent Osborne on July 21, 2016, and it's the final season of the show. According to Adam Muto, the number of episodes ordered by the network as part of the season was substantially lower than it had been, leading the production crew to believe that the series is either ending or going to end soon.

Storyline writing for the season ended in mid-November 2016 and the last storyline meeting was held on November 21. Osborne tweeted that the show's final script was pitched to storyboarders on November 28; the episode was pitched to the show's producers during the third week of December 2016. A number of voice actors, including Maria Bamford and Andy Milonakis, confirmed that voice recording for the season (and series) ended on January 31, 2017. Regular production of the series ended on November 16, 2017.

Unproduced episodes

These episodes were planned, and are known from design documents released by Frederator Studios in 2009 during the production of the first season. However, they were not produced for season one, and it is unlikely that they will actually be made into full episodes but it isn't unheard of for an unproduced episode to get produced eventually. Adam Muto has confirmed "Jakesuit" eventually worked its way into "The Silent King,"^{[citation needed]} and it got its own full episode only five seasons later, "Jakesuit" became "Jake Suit."

"You're a Beautiful Dancer"

"Brothers in Insomnia" was originally episode #692-002. However, it was scrapped, and its production number was taken by "Rainy Day Daydream," which was actually one of the last episodes produced for season one.

The Frederator blog also posted notes for an episode that was thought to be titled "You're a Beautiful Dancer." However, Adam Muto later confirmed that "You're a Beautiful Dancer" was just a quote that Finn was saying to Jake and was never meant to be an episode title. He stated that the page in question only contained random story ideas that were never fully developed into episodes.^{[citation needed]}
