Eat a cookie

You search many hours for a cookie to eat. This is perhaps the hardest part of your cookie eating procedure, since this is hell, there is not much in the way pleasant things such as cookies for you to enjoy. Nevertheless you eventually find a cookie. It stands upon a pedestal surrounded by a sea of hellfire. But you're used to the hellfire now, so getting to it is no real problem.

  You take the cookie in your hands, and messily devour it. It tastes terrible, probably because this is nether hell, and you're supposed to suffer eternal torment and all that stuff.  You sigh dejectedly.

  Suddenly, and without warning, grow a pair of horns.  Then your skin turns a deep red, and your body becomes much more muscular.  Also, a trident appears in your hands, though how it got there is a mystery to you.

  You realize in time that you've just eaten the darkest treasure of hell - The Evil Cookie of Evil Chocolate Chips.  It was just barely evil enough to beat out the broodwich* in last years evil foodstuffs competition, so great was it's evil.

  Not wanting all that precious evil to go to waste, you don a cloak of darkness, adopt the cool name Hellcookie, and return to the world of the living to terrorize the mortals.
