In the Gumbaldia episode Finn and Jake, as ambassadors of the Candy Kingdom, travel to a powerful new city-state in a last-ditch effort to stave off war. But they have to be masked, so Jake became into a hat from a dog for this mission. By the way, it's a beautiful yellow hat, but it seems, this is a woman's hat. If you want to try this too, Adventure Time Jake Hat Sticker would help you with this situation.
