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.[6] 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. 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.[3] The series began with Fionna and Cake awakened in an alternate world where there is no magic and they can't remember their lives of adventures.
