After watching the latest episode of MLP:FiM (28 Pranks Later), I decided to this piece from the beginning of the show. I can only guess I got it even close to right. :P As for the title, Silver Quill (you can find him on YouTube) came up with the name on Equestria Daily "Discord! No, wait. Changeling! Um... Change-cord! Sorry, I have Changelings and Discord on the brain lately."
