Fionna and Cake

Fionna the Human and Cake the Cat are the protagonists of fan fiction written by the Ice King based on Finn and Jake. Or so it was thought. In actuality, the cosmic being Prismo the Wishmaster created Fionna and Cake's universe based on his friends Finn and Jake and hid it in Ice King's head to hide it from the cosmic authorities. When Ice King was freed of the crown's influence and transformed back into Simon Petrikov, the magic was drained from Fionna and Cake's world as well. After being pulled into Simon's universe by a botched summoning ritual, Fionna and Cake join Simon on a multiverse-hopping quest to bring magic back into their lives.

Feats from Adventure Time proper will be marked with the season and episode number. Feats from the Fionna & Cake series will be marked with F and the episode number.
