A DeviantART user by the adorable name of TiffyyyCuppyCake has created an assortment of wonderful and enchanting custom-made Adventure Time covers for the iPhone.
Although they look like deliciously edible cupcakes, they are actually created using fake frosting. They each possess a harmonious balance between cupcakes, a phone case and Adventure Time.
Each of the Adventure Time cases feature characters attached to the case along with an assortment of magical accessories, designs and toys. I wouldn't be surprised if there was unicorn dandruff sprinkled on each one as well.
Although the cases would surely not be as functional as they are fun, they certainly look like they would taste good.
