The Santa Pony was just practicing his flying route when a horrible mid-air collision happens. Derpy was only trying to deliver some Christmas cards! But the muffin-loving mare is charged with the hospital bill. Being only a mail-mare, she can't afford it. But Santa notices that she is a mail-mare, so she can deliver things. The solution: Derpy delivers the gifts on Christmas night and she won't have to pay the hospital bill. This can only end well...
