I don't know a thing about Adventure Time, so this was kind of a stab in the dark. I actually feel a teensy bit bad for whomever will conclude this comic, since I have no clue if they'll know anything about the show either.
Anyway, this took me a very short amount of time. It was just a scribble in Manga Studio. But I can explain my haste. I injured my back last Thursday, and I haven't been able to do much of anything. When the deadline sneaked up on me, I was like, "OH, SNAP!" So I whipped this little doodle together in the nick of time.
