Adventure Time: Fionna and Cake recap
An adult spin-off on HBO Max. Fionna Campbell and her cat Cake are gender-swapped versions of Finn and Jake, first invented as fan fiction by the Ice King. In their own world there is no magic, and Fionna works dead-end jobs. When magic suddenly appears and then goes wrong, Cake vanishes and Fionna goes looking for her. Their search leads them to Simon Petrikov, the man who used to be the Ice King, now cured but depressed and still missing Betty. Together they travel through the multiverse, visiting versions of Ooo that took different turns. They learn that their world was made without permission by Prismo, the wish master, and that Scarab, a cosmic auditor, is coming to delete it. Season 1 aired in 2023; season 2 followed from October to December 2025 and brought in Huntress Wizard, who travels between worlds to save an ailing Finn while Fionna fights to save a café from eviction.
