Mirror just wants to have some fun. She thinks moving to Manehattan is just the thing, lots of new ponies to meet, good food, great nightlife scene, random interdemensional portals opening in the middle of the street, the works!

At first she thinks it's a bit strange having a human embassy crop up a few blocks away from her apartment, but when she's one of the select few invited to be the first ponies to visit the planet Earth, it's hard to refuse.

When she does get to the other side however, she finds the roles have been reversed. She's the strange one, and even a little famous as the first extraterrestrial ever encountered by humanity.
