Late one night Scootaloo, wakes up to see Applebloom not in her sleeping bag and Sweetie Belle in the corner with her gut open.

I have no idea what to call them, Cutie mark freaks? No, Cutie mark monster? Just call them what you like.
Also be warned, this story is so random, I had to look through smoke and mirrors and have armed guards outside my room just to write it!
