The Cakes got an order for a certain treat, one of the ingredients calls for a certain berry, and is known to grow only on the Everfree Forest. Pinkie gladly agrees to fetch the berries, and decides to take a break while she's there. Though strange things begin to happen, she decides to end her break early and goes back to the Bakery, until she is stopped by a strangely comical hooded skeleton.
