Screaming is coming from the camp known as Camp Crystal Lake. A couple is running like hell from an unseen attacker. The two then eventually run into a dead end in the woods and then the mysterious asassin is revealed. He was wearing a jumpsuit of some sort, his skin was all fleshy and gross, he had a hockey mask over his face. He was also carrying a machete. He was approaching closer and closer to the doomed couple. Eventually the male grabbed a book and started speaking an incantation. Suddenly a circle of egyptian hiroglyphic appeared around Jason. Then a lightning bolt struck and suddenly a portal appeared and sucked Jason into the portal. As he was falling throughout the space-time continum thoughts of his mother went sprawling throughout his mind, if he has one. And then all went dark.

It was a dark night in Equestria and the date was Friday the 13th.

Inside a treehouse the Cutie Mark Crusaders were trying to think of excellent ways to earn their cutie marks.

"I got it! We could try carpentering." Apple Bloom said.

"No we already tried. We could try timber wolf hunting." Scootaloo said.

"Absolutely not. I say we should try getting our cutie marks for sewing."

Sweetie Belle said. "Boring." the little daredevil said.

Suddenly they heard static electricity go off. The three then looked through their telescope to see a large electric bolt fly throughout the sky and land somewhere in the Everfree Forest.

"What the hay was that?" The little apple maker said surprised.

"I got no idea. Hey! I think I got an idea on how we can earn our cutie marks." The young dressmaker in training said.

"Really what?" Apple Bloom and Scootaloo asked.

"We try to solve the mystery of what that was and where it landed." Sweetie Belle said.

The three then agreed and then shouted into the air, "Cutie Mark Crusader Mystery Solvers!"

They then rushed down the stairs towards where the bolt landed. Unknown to them they would unleash the most violent murder of all time on Ponyville.
