Fluttershy buys a painting from a new stall in Ponyville markets. It's a quaint picture of a rural cottage surrounded by grasslands and farm animals. It fills her with a curious feeling of longing that she hasn't felt before. Why should she? Her life is already like it.
But new animals start appearing around her home, and her own animals begin disappearing. Why and how she doesn't know, but she has to save them. She has to save all of them.
