Foreign Object is a 1k Horror Comedy. In it, Twilight learns to appreciate the culture's of other creatures.
Twilight goes back to the School of Friendship to see how things are going, only to see that the changeling teacher does live demonstrations of the inner workings of her biology, and presumably of other creatures.
There's really not much else to this story, other than Twilight's subdued reaction. Not sure what I was expecting going in.
