List of episodes/Season 5

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."
