Enjoy!

(Update) I heard MisterDavie's MLP videos were taken down and that's why i made that little memorial clip in the beginning, however I just noticed Smile HD is back online but the other two aren't yet. I really thought they would all be gone for good since he never made a video in 2 years and left his channel but I guess not, odd.
