Looks like somepony found Trot Smiles. First.

Something has destroyed Ponyville, turned its resident into monster who crave for flesh, only a few are left to fight off the new evil living in their town. Thunderlane is among the few survivors, and he has to find his little brother who is still alive and is somewhere in town, but he knew that wasn't his only missing, for if he and his fellow survivors lost their life, he will never find his brother, and most importantly, their former selves will suffer a fate worst than death.
