Uncivilized Elk | Adventure Time Review: S9E12 - Fionna and Cake and Fionna @uncivilizedelk | Uploaded August 2017 | Updated October 2024, 7 hours ago.
An old Fionna appears in the regular Adventure Time world! Everybody is confused, except Ice King, who discovers it was a mummy. I mean an old lady. Also there's a laser that beams Fionna and Cake adventures into Ice King's melon every night. Weird.
