Pinkie Pie decides to visit Twilight one afternoon, but Twilight says she is needed in Canterlot to help plan a royal banquet, as well as attend it herself. Pinkie offers to watch over her library while she's gone, which Twilight had accepted, since it was short-notice. After being left alone for a while, Pinkie Pie gets bored and chooses to snoop around some of Twilight's experiments. Pinkie discovers a strange looking clock in her room with many different buttons on it, showing numbers. She randomly selects buttons, and has done what was thought to be impossible.
