Essentially, Fluttershy's Lament, Join the Herd, Digs at the Ground from Friendship is Musical, and Avast Fluttershy, at the same time. I have also added brief excerpts of "Pony Girl" by Tridashie and "Loyalty" by AcousticBrony & MandoPony, since I had to cut out Join the Herd to keep this at least somewhat musical.

Here's URLs to everything I used:
