Fionna and Cake

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

Synopsis
In a 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 Gumball 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 retractable sword in it. The group rides off, and Prince Gumball challenges Fionna to a race to the Marshmallow Meadows. 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 and locks the door. 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 saying how she doesn't need a boyfriend after all, and that 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 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, but having no spoken role in the main episode, it is unknown whether Beemo has gender-swapped or not.

Music

 * Oh, Fionna

Pre-premiere internet leak
In mid-August the episode was leaked and illegally uploaded to YouTube prior to its television premiere. The original source of the leak is currently unknown. Most illegal uploads of the video were terminated by copyright violation notices from Cartoon Network. This episode and "The Monster" were screened early at an Adventure Time event at the Paley Center. However, Natasha Allegri confirmed on her Formspring that the leaked episode was posted days before the screening, and that the leaking of the episode wasn't related to the screening in any way. There have been many discussions prior to the official air date if this leak was a finished or work-in-progress version of the episode. But currently the consensus is that the official episode and the leaked episode are the same.

Trivia

 * Along with "What Was Missing" this was the only episode that had a slight part of its storyboard revealed before the season three promo.
 * 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!"
 * Natasha Allegri confirmed that this will be the only gender-swap episode of the season.
 * The music used in the beginning of the episode was the same music heard in the beginning of "The Enchiridion!."
 * The other gender swapped characters Lumpy Space Prince and Marshal Lee had no major role besides being guests at the ball.
 * It is peculiar that Marshall Lee even exists in the Ice King's fan fiction, 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.
 * This is the first episode where both Finn and Jake are minor characters and Jake didn't have lines in this episode because his head is stuck in the ice.
