Personally, I can't stand Adventure Time (The animation doesn't sit well for me, and I don't find most of the humor very funny, tbh.), but to each his own, and it is funny to see what everyone would be as the cast of Adventure Time. Had to say... though... the roles were both surprising, and yet expected.
Now, here's the eternal question... is Podi the Ice King or Marceline? Or some other character that I prolly don't know because I don't watch the show all that much?
