Pinkie Pie's cupcakes are well-known delicacies in the town of Ponyville, and you can find them at almost any of her parties. In other news, Carrot Top has some errands to run before her picnic with Derpy Hooves. The final item on her list is to pick up some baked goods from Sugarcube Corner, and what would be better than some cupcakes? But when she samples one, things go south when she wakes up in a secluded part of Pinkie Pie's "Party Cave." Not to mention, Pinkie Pie has an unexpected visitor from out of town.
