Pinkie Pie invited you to make cupcakes with her and since you had nothing better to do. You agreed to it and soon got there where you helped her out with getting batter ready and stuff until she bonked you on the head then you woke up strapped to a table...you saw the heads of your friends on the wall. Then saw Pinkie Pie.

Pinkie Pie: "Finally awake sleepy head? I thought I hit you too hard there but thank goodness your up. This will be fun."
