Rainbow Dash hardly ever walked anywhere. Applejack noticed this and, out of the blue, decided to make a bet with Rainbow: "If you can go the whole day without using your wings, I'll let you be the very first in line for cider season." She knew Rainbow couldn't turn down a challenge; she was right. Five hours after the bet was made, Rainbow Dash came across something...odd. What is it? What will she do with it?
