Adventure Time creator Pendleton Ward and developer WayForward have been quite clear about their influences, and the resulting love letter to The Legend of Zelda is starting to look pretty sweet and or math.

Adventure Time: Hey Ice King! Why’d You Steal Our Garbage?! arrives on DS and 3DS in October – complete with interrobang.
