List of episodes

Season 2: 2010-2011
Season two contains 26 half episodes and originally aired from October 2010 to mid-2011. Their titles and production codes were revealed on the Frederator Blog.

Unscheduled episodes
The following are production codes and episode titles for season three episodes that have not yet been scheduled. They were posted to the Frederator Blog on April 6, 2011 by Eric Homan, the vice president of development at Frederator Studios.

Season 4: TBA
In a tweet on May 2nd, 2011, Pendleton Ward mentioned, in a correction to commenters who claimed Mortal Folly and Mortal Recoil were the series finales instead of the season finales, that the Adventure Time staff was currently working on writing the Season 4 scripts. The season will see the premiere of the 100th episode of the series, "Prince Huge". Adventuretimeart.frederator.com/post/11374501927/100th-episode-tom-herpich-and-skyler-page-this]

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. According to an old blog post, "Ice King Has a Point" was supposed to be a 27th episode of a 26-episode season, because episode #6 had been scrapped. However, because episode 6 ("What Have You Done?") actually was eventually made, it's likely that "Ice King Has a Point" was either canceled or incorporated into "What Have You Done?"

"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.

Adam Muto has confirmed "Jakesuit" eventually worked its way into "The Silent King", which may give hints about the plot outline of "Jakesuit".
