Storyline

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 whom 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.
