what episodes of adventure time are fionna and cake in
Fionna and Cake The concept of Fionna and Cake was based on sketches that series' character designer and storyboard revisionist Natasha Allegri made. Ward was pleased with her creations, and decided to canonize them. Originally, the episode did not feature the Ice Queen at all, and the middle part of the episode saw Fionna go on a date with Gumball to a restaurant; this subsequently changed. The episode was watched by 3.315 million people, making it—at the time—the most-watched episode of the series. "Fionna and Cake" received largely positive reviews from fans and critics alike. Two sequels to the episode—"Bad Little Boy" and "The Prince Who Wanted Everything"—were produced during the show's fifth and sixth season, respectively.
