You take chase after the pony, your shoes striking the pavement almost as hard as you hear the pounding of the pony's hooves up ahead. It takes a sudden turn and vanishes into some bushes and you scramble after it, getting some sharp thorns digging into your flesh, but you don't lose them. You burst through someone's backyard and thankfully they don't notice as you barrel straight through, following the trail of destruction the pony's leaving behind in its wild flight. Fortunately, its presence also makes it easier to follow.
While some things try to slow you down, the worst of it had to be dealt with by the pony first, giving you the edge. You have to catch up to it, you just have to! How many other chances are you ever going to get to see a real pony. That purple fur, that red splash on the tail. It was a magical pony, you're sure of it. You didn't get a chance to see its cutie mark beyond that it definitely had one.
You burst through a fence and almost tumble down a small ditch that leads to a small river. The pony is there, shaking and looking around wildly. You are the one it keeps looking at. Now's your chance!
