When a seemingly injured bat bites Fluttershy, she doesn't think much of it (other than the disappointment of not being able to help a poor creature). When she looks in the mirror however, she see's the last pony she wanted; a half pegasus, half bat. This has happened once before, and it wasn't a good thing, but, the difference this time is, this bat isn't craving apples. This bat is craving something much sweeter...
