There has long been a secret in Equestria, known only to those who have become mothers. It is known simply as the 'naming dream', a personalized dreamscape greeting from one of the princesses, where they praise the expectant mare for bringing forth new life, and give them a suggestion on what to name their foal. As almost every pony in Equestria has a name that lines up with their future endeavors, this suggestion is almost always taken to heart.
Unfortunately, it is not always the case. After seeing her daughter turn over a new leaf to help the "blank flanks", Spoiled Rich takes a look at herself, and her life. She has lived a privileged life, and is indeed spoiled. But why was she given the name Spoiled Milk? Only one pony in Equestria would have that answer: Princess Celestia.
