I think that even though Ice King had made them from a figment from his imagination, i believe that they actually live in another part of the world, that there's a continent right beside the land of Ooo. And that it had been a coincedence that Ice king made a fan fic about them. What are your thoughts on the subject?
Also, i imagine that one day Fionna and Cake are adventuring in the land of Ooo and they stumble upon Finn and Jake. How would they react?
And if they do happen to appear on another episode, would you think it's Ice Kind w/ it's fan fic, or that they're real?
These are the things i've wondering about lately......^ - ^
