Pinkie Pie receives a letter from her family. Learning that one of her sisters is going to have a foal, Pinkie decides to travel home to the rock farm to visit. And her best friends in the whole world agreed to come along! Little do they know that Pinkie's native lands are going to put their survival skills and even their very souls to an unforgiving test...
