(Takes place between "The Ending of the End" and the time skip shown in "The Last Problem".)
Sugar Belle is pregnant and is expecting her first foal very soon. Big Macintosh, the soon to be father, is excited and so is everypony else who knows.
However, Sugar Belle can't help but feel a little nervous and bored. So to help take her mind off her problems, Big Mac offers to tell his wife what his parents went through with their first foal (him).
Will Sugar Belle learn anything of value from this story? And how much does Big Mac really know about his family's past?
