An series of unfortunate events involving poor timing, someone not paying attention, and Fluttershy's usual batch of terrible luck forces the timid teenager into a situation where she's streaking through her home town with no way of getting in touch with anyone.

While she should be mortified, and at first is mortified, she quickly discovers something about streaking through town, having your body completely exposed, and knowing that at any moment someone could catch you...

It's actually kind of fun.
