Fluttershy was driving through the night until her car broke down. She called Twilight what happened and realized that she's in a neighborhood where it's not safe. Twilight tells her there's a creature who'll catch her and how to avoid it. Fluttershy has to survive until sun rise or she won't be heard from again. The creature is attracted to light and sound which causes it to charge toward where the light came from. Once the sun rises, Fluttershy will be safe, and she'll be rescued.
