It's bad enough when you're having a bad day, but to wake up the completely wrong species? And have the only pony who can help fix this be in another city several hundred miles away? Much worse.
But for two young ponies, who have already gone through hell not one month ago, surely that's as bad as it gets, right? It's not like they're having any other problems, right?
They are?
It's going to be one of those days, apparently.
A new pony arrives in town, and all she wants to do is leave. But why? And what's her connection to Twilight Sparkle?
Two ponies, with one problem, and all they need to do is get to Canterlot to solve it. Should be simple enough, right? Of course not!
