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.

Trivia

 * It has been confirmed that Fionna will be 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. It is possible the leaked episode is a fake version intentionally leaked to protect the real episode.
 * 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.
 * 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.
 * On some TV guides, it says that Fionna and Cake live in the land of Aaa, but this could have changed, since Natasha does not know what the land of Aaa is
 * The music used in the beginning of the comic con was the same music heard in the beginning of The Enchiridion.
