I WARNED YOU ABOUT THE CUPCAKES. I TOLD YOU DAWG
From Screamer Wiki
This particular YouTube video, uploaded by use Jaredraptor in March 2011, is a little strange. This screamer is essentially a heavily edited version of "My Little Ponies - Cupcakes", starting directly with Applejack's POV. However, when Pinkie reveals her creepy face, she instead emits a harrowing female scream (the same in such videos like suicidemouse.avi) combined with a roar. The video ends with a close-up of Applejack's shocked reaction to the face.
