Scootaloo has a dream, but certain circumstances hinder her ability to reach her goals. At the tender age of 15, she receives news from her local doctor that her wings struggled to develop at a young age, and therefore are unable to carry her current body weight. Because she is past core development stages, it is highly unlikely she is able to fly now or even in the near or far future.
After months of suffering through crippling depression and ridicule by other Ponyville citizens, by word of mouth she hears about a doctor in Manehattan that might potentially be able to cure her ailment.. but she learns that this doctor may not be all that he seems.
