If you were wondering if the new Adventure Time show Fionna and Cakeis a spinoff or a sequel to the main series, the simple answer to this question is: yes <3

The more complicated answer is that Fionna and Cake is surprisingly an incredibly direct sequel to Adventure Time. At the same time, the first episode basically kicks off in a completely different universe, one where magic isn’t really a thing, and introduces a version of Fionna and Cake (the gender- and species-swapped versions of Finn the Human and Jake the Dog) that exist outside of the Ice King’s fanfiction. At first it feels a little bit like a separate thing, but then it neatly picks up right where Adventure Time left off — both in a canon sense and in regard to the core audience.
