The Hu-Mane 7 was having their fortnightly slumber parties but this with a twist: Princess Twilight from Equestria had the free time to come to this one. So now, two differently Twilights were attending the same party and things are going as well as you might expect.

But then, one of their friends had come up with an idea with a game: see if they can tell the two Twilights apart. The Twilights must mix themselves up and everyone else must see if they can tell which one is a pony princess and the other one as the nerdy girl that they go to school with. Despite some reservation, both Twilight decided to play along.
