Fionna and Cake

"Adventure Time with Fionna & Cake" is the 9th episode of season three of Adventure Time.

Synopsis
In a "very special" episode, Fionna (the gender-swapped version of Finn) puts up with the sudden courtship of Prince Gumball while taking advice from her partner Cake in dealing with guys.

Plot The episode opens with an alternate version of Finn and Jake's, with gender swapped characters. Fionna and Cake are helping Prince Gunball decorate for the upcoming ball, when Gumball asks Fionna if she would like to go with him. Their conversation is interrupted when Cake comments on how her tail is quivering, and Fionna rushes onto the balcony to see the Ice Queen coming down from dark clouds. The Ice Queen turns into a slushie monster, and Cake turns into a morning star that Fionna uses to destroy the monster. The area is enveloped in a snowstorm, and Gumball comes out of the snow. Fionna asks were the Ice Queen went, and Gumball says she must have got away.

Prince Gumball then asks Fionna to "go out" with him, and Cake agrees for her. Fionna and Cake meet Prince Gumball at the Royal Gardens, and Prince Gumball introduces Lord Monochromicorn, the alternate to Lady Rainicorn, who is a stretchy black unicorn who speaks by tapping the ground with his hoof. Prince Gumball gives Cake a bag of catnip that Lord Monochromicorn picked himself, and give Fionna a bouquet of posies with a crystal retracable sword in it. The group rides off, and Prince Gumball challenges Fionna to a race to the Marshmellow Mweadows. The group races there, and Fionna and Prince Gumball jump off their friends into the flowers. Prince Gumball jumps into the flowers, and Fionna goes after him. she pulls him up, and he has a pygmy crystal skull which he says reminded him of Fiona's shiny eyes. The group then flies off on Lord Monochromicorn, and Prince Gumball sings about Fionna. The flight ends when the two get off of Lord Monochromicorn, and him and Cake fly off, leaving the two alone.

At this point, Prince Gumball asks Fionna to come to the Ball with him, as his girlfriend. Fionna rushes home, and Cake dresses her up in a dress. Fiona takes the retractable crystal sword with her, because she is leaving her pack behind. Him she gets to the ball, Prince Gumball takes Fionna to his room. She becomes flustered when he begins to take his clothes off. A drip of water lands on her shoulder and she looks up to see the real Prince Gumball trapped in ice on the roof. The fake is revealed to be the Ice Queen. Fionna becomes enraged because of the deception, and takes out the sword to fight, but the Ice Queen turns it into a lump of ice that traps both her hands. Fionna uses it to smash the Ice Queen over the head, and she flies up to release Prince Gumball. Cake enters the room and the Ice Queen blasts her with magic. Fionna runs up and kick her crown off, squelching her powers.

She delivers a vicious punch for "messing with her heartguts" and Cake uses the crowns power to blast the Ice Queen. Fionna ends by says how she doesn't need a boyfriend after all, but she would love to date the Ice King. The screen changes to the real Ice King reading a fan fiction he wrote to Finn and Jake, who are trapped in ice.

Opening sequence

This episode features a modified version of the Adventure Time Theme Song, sung by Natasha Allegri instead of Pendleton Ward. The sequence is identical to the regular version, although all the characters are replaced by their gender-swapped counterparts.

Aside from the main characters, all the Candy People (including Lollipop Girl and Mr. Cupcake) and Tree Trunks have had their genders reversed. Where Gingerbread Muto usually appears on the castle balcony, a Gingerbread Rebecca Sugar can be seen instead, which is appropriate because Adam Muto and Rebecca Sugar were the storyboard artists for this episode. Notably, Beemo appears the same, supporting the fact that Beemo has no gender.

Music

 * Oh, Fionna

Trivia

 * Fionna was voiced by Madeliene Martin, Cake by Roz Ryan, Prince Gumball by Neil Patrick Harris and Ice Queen by Grey DeLisle.
 * Along with "What Was Missing" this was the only episode that had a slight part of its storyboard revealed before the season three promo.
 * This episode, along with "The Monster," was shown at Paley Center
 * This episode was leaked and illegally uploaded to Youtube about two weeks prior to its television premiere. The original source of the leak is currently unknown. It is also unknown whether this is a finished or work-in-progress version of the episode. Most illegal uploads of the video were terminated by copyright violation notices from Cartoon Network.
 * The preview vs. the illegal episode and the sneak peek on[http:// cartoonnetwork.com cartoonnetwork.com], there is a difference in audio during the decoration of the candy hall. This maybe an audio swap decided some time after the preview. To hear the differences skip to 00:27 on the preview video from youtube and the sneak peak video from cartoon network.
 * Natasha confirmed on her Formspring that the leaked episode was posted days before the episode was screened at the Paley Center, and that the leaking wasn't related to the screening in any way.
 * 1) This wasn't true, as it turns out the real episode was the same thing as the leaked episode.
 * Cartoon Network released a five minute clip for the episode.
 * On Rebecca Sugar's tumblr, she said there was an idea for Fionna and Prince Gumball to their date at a restaurant [sic]. She later said the idea was cut to add more action to the episode. However she later states that "...and if there had to be a date, it would be a date with swords and skulls and fighting!"
 * The snail is seen after Fionna kicks a Jelly Kinder on the ceiling of the Candy Castle.
 * Natasha Allegri confirmed that this will be the only gender-swap episode of the season.
 * The music used in the beginning of the comic con was the same music heard in the beginning of "The Enchiridion!"
 * The official episode and the leaked episode are the same.
 * The other gender swapped characters Lumpy Space Prince and Marshal Lee had no major role besides being cameo characters at the ball.
 * It is peculiar that Marshall Lee even exists in the Ice King's fanfiction, particularly since Marceline has yet to have any actual interaction with the Ice King as of this episode. (they have been in two episodes where they both appeared in, but have never interacted either time as of yet)
 * Before the final revelation of the Ice King's involvement in this fan-fiction, he had his characters speak of his greatness, giving off elements of both being self-insertion and himself being a Mary Sue in this universe.
 * Already, controversy is developing over the ending of the episode, just as there was controversy over the ending of "Too Young".
