Warner Media said in a press release, “HBO Max has given a series order to ADVENTURE TIME: FIONNA & CAKE (wt), an all-new half-hour young adult animated series starring the fearless sword-wielding adventurer, “Fionna,” and her magical best friend and talking cat, “Cake.” Produced by Cartoon Network Studios, the ten-episode series will explore their relationship and the mysterious land of Ooo. Adam Muto (“Adventure Time,” “Adventure Time: Distant Lands” specials) will serve as showrunner and executive producer.”
They continue, “Fionna and Cake – with the help of the former Ice King, Simon Petrikov – embark on a multiverse-hopping adventure and journey of self-discovery. All the while a powerful new antagonist determined to track them down and erase them from existence, lurks in the shadows.”
HBO Max exec Billy Wee said, “Adventure Time truly broke the mold and earned legions of passionate fans in the process.” He added, “We are thrilled to partner with our friends at Cartoon Network Studios to continue innovating and expanding the Adventure Time universe with this world class team.”
“‘Adventure Time’ broke boundaries and was a shining example of how impactful animated storytelling can be. We are excited to partner with HBO Max to carry that tradition on to new heights, lands and magical worlds,” Warner Bros. Animation and Cartoon Network Studios Sam Register continued.
The gender-swapped characters first appeared in “Fionna and Cake,” the ninth episode of ‘Adventure Time’s third season where Finn and Jake are forced to listen to The Ice King’s fanfiction. It was released on Cartoon Network on September 5, 2011 and was the highest-rated episode of the time.
