You were wandering through Paper School, noticing markings on the wall that pointed to a blue door saying “DO NOT ENTER”, but who was gonna stop you? You ignore the warnings and open the door anyways, and when you enter, you notice everything goes from 2D to 3D, and there was a girl standing there staring at you, in a moments notice spikes come from the ground around you, and she lunges at you at fast speeds, claws out.
