- According to Adam Muto, Princess Bubblegum and Marceline's kiss wasn't in the original story outline. The scene's direction was left to Hanna K. Nyström's discretion, as the outline simply said they "have a moment." When the scene was storyboarded, there was a note in the margin simply saying "Come on!" with a large exclamation point.
