Adventure Time: Fionna and Cake
Adventure Time: Fionna and Cake is an American adult animated television series developed by Adam Muto for the streaming service HBO Max. It is a spin-off of the Cartoon Network series Adventure Time (2010–2018) and the third main installment in the Adventure Time franchise. The series premiered on August 31, 2023; the second season premiered on October 23, 2025.
The series follows the eponymous Fionna and Cake the Cat, alternate-universe versions of Adventure Time's main characters: Finn the Human and Jake the Dog. Also featured is Simon Petrikov, who originally appeared in Adventure Time as the Ice King. Fred Seibert and Sam Register serve as executive producers alongside Muto, who himself served as showrunner for the last six seasons of Adventure Time and oversaw production of the Distant Lands specials.
Where Adventure Time follows the adventures of Finn the Human and Jake the Dog, Fionna and Cake follows Finn and Jake's gender-swapped counterparts, Fionna the Human and Cake the Cat. The series also features Simon Petrikov, a character who for most of Adventure Time had been known as the Ice King.
Fionna lives with her cat, Cake, in a universe without magic, spending her days cycling through dead-end jobs. At night, she dreams of a magical yet elusive world where she can find fulfillment. Simon, in the alternate universe home to the Land of Ooo, works from home as a living exhibit of a bygone era and faces similar anxieties to Fionna's. The trio travel throughout the multiverse, stalked by an antagonist who seeks to erase them from existence.
The idea for "Fionna the Human" and "Cake the Cat" evolved from drawings that Adventure Time character designer and storyboard revisionist Natasha Allegri had posted online during the show's earliest seasons. Reception to the gender-swapped characters was so positive that the Adventure Time producers decided to write the characters into the series. They debuted in Season 3's "Fionna and Cake", on which Allegri worked, and it functioned as both "a jab [and] a huge celebration of, [sic] the feeling of being a fan" and "allowing something completely ridiculous to make your heart tighten". The characters would make additional appearances in Season 5's "Bad Little Boy", Season 6's "The Prince Who Wanted Everything", Season 8's "Five Short Tables", and Season 9's "Fionna and Cake and Fionna". In these episodes, Ice King shares stories about Fionna and Cake he made, who are in fact characters from modern shows; when he sleeps, a beam projects to his head to transport ideas of the fan fiction.
After the 2018 finale "Come Along with Me", a first spin-off series of Adventure Time: Distant Lands debuted in 2020; before the latter's finale, HBO Max announced that a gender-swapped spin-off series was in production, on August 17, 2021, and ten half-hour episodes were planned. In a 2022 interview, Jeremy Shada, the voice actor of Finn the Human, noted that he "may or may not be in that" when it came to the new spin-off. In the Annecy International Animation Film Festival in 2022-23, Cartoon Network and HBO Max released sneak peek material.
The Adventure Time: Fionna and Cake series was developed specifically with the young adult demographic in mind, according to Suzanna Makkos, an executive for both HBO Max and Adult Swim: "The Adventure Time fans have grown up and people are still coming in the bottom, and they're aging up", she noted in an interview with Comic Book Resources. "[Fionna and Cake] felt like a perfect show for us. Tonally, it is very much Adventure Time, but Fionna's older. She's in the workforce. It's more adult, so I think it's going to bring in new fans, and it's also going to serve the fans that we already have." In the United States, the limited series received a TV-14 certification based on the adult content (nudity, gore, profanity, and substance abuse); on the other hand, the series remains the TV-PG rating, just like Adventure Time, in Australia. Longtime Adventure Time and Distant Lands executive producer Adam Muto returned to produce the limited series and also served as the showrunner, with Fred Seibert and Sam Register in partnership with Cartoon Network. In interviews with The Direct and The Washington Post, Muto and Ryann Shannon explained that the crew decided to focus on Fionna and Cake due to their popularity with the Adventure Time fandom. Initially, Muto was concerned about working on another spin-off, given that sequels and reboots are often met with mixed success. To ensure that Fionna and Cake felt like its own production, the crew attempted to avoid "stepping on what [they had already] done before". The writers thus decided to ensure that the spin-off would be satisfying on its own and that it would focus on the characters' unique growth. While Distant Lands is a limited series of four loosely connected vignettes, Fionna and Cake is a more united story.
When discussing how the production crew differentiated Fionna and Cake from the original Adventure Time series, Muto revealed that the crew members "were looking for ways to explore stories and characters that can be pretty different than Finn." While Finn is a selfless and energetic hero, Fionna is more ordinary and realistic, since she does not live in a world of magic and is not as skilled as a fighter. In this limited series, therefore, the writers "wanted to see where [Fionna would] go if she kind of knew about that magical world from the first series which had been denied her". Muto later added that the crew attempted to make Fionna more than just "Girl Finn" by giving her a unique personality that, in certain respects, is "way different than Finn and others." The crew also took this contrasting approach when working on Cake: While Jake is a lazy dog with the power to stretch his body into a whole number of fantastic shapes, Cake lacks magic powers and begins the series as a regular house cat. As to Jake's uncertain death, Muto decided to leave it ambiguous and noted that he does not want to "say definitively what the answer is". For adult Finn's possible future adventures, Muto liked the idea of Finn living his own life, and so they decided to not feature him in more than a few episodes. To make up for this, the writers brought back Farmworld Finn, a character who is different from the Finn of the main series. Previously, while both the voice actors Olivia Olson and Erica Luttrell are of African descent, and Marceline's mother was a person of color, Marceline and Marshall share the look of gray vampire skin; in Fionna and Cake, Marshall Lee is with dark skin as a human character. The series makes a number of references to the 1982 sitcom Cheers. Muto explained that at first, references to the show were a joke, and that many of the crew members had never actually seen the production. Initially, the song had been featured in the fifth-season Adventure Time episode "Simon & Marcy", wherein it was used by Simon as a way to retain his sanity. In Fionna and Cake, the sitcom and its theme symbolize Simon's life before his discovery of the ice crown, and in Fionna's world, it is the only television program available, reflecting the fact that Simon is mentally stuck at that point in time. The crew considered writing an episode that would take place in the world of The Marvelous Misadventures of Flapjack. Although this idea was never fully realized, the series is briefly referenced in a scene in episode "Prismo the Wishmaster", wherein Prismo shows Fionna, Cake, and Simon a variety of universes. The inspiration in animation often came from Seattle, where Muto was born; a building as seen in the episode "Jerry", is based on Suzzallo Library in the University of Washington.
