Ever since " Cupcakes " was created a portal kept opening up on the outskirts of Ponyville. Nobody or pony has discovered them until Ben hooked up a machine to transfer people to different dimensions as long as they had a Creepypasta history. But after Ben sent Jeff to this dimension, the machine got overheated and was sent into overdrive. It broke, and the portal shut trapping Jeff in the world of Equestria.
