"STOP THAT PIGGY!"
The call rang throughout all of the dungeons, the eerie flash of lightning before thunder rumbled in and disrupted life as all knew it. Those in the classroom looked up from their work and glanced at each other, looking around to see where such a cry might have come from. The students had no idea, but could not wholly abandon a perfectly good distraction from their work either. It seemed, however, that they would not be affected by the strange cry. With sadness in their hearts, the students settled to continue on with their work.
And suddenly, chaos struck. A pig was launched into the room, carried on large wings that looked a lot like those of a hummingbird, but much larger. The poor pig was not in control of the movement of the wings, and was squealing its misery at the top of its lungs. The wings spun him around the heads of the students, before sending him diving towards a table with a Slytherin boy and girl.
Darcy ran into the room, misjudging how slick the dungeon walls were. Her foot went over her head. "Piggy-yyyyyyyyyyyyyy!" The word elongated into a cry as she fell flat on her bum.
