The Cutie Mark Crusaders decide that they want to have a sleepover with some friends. So, they ask around, until confirming the location at Fluttershy's house. Fluttershy, unable to think of how she'd manage to handle all of those foals, employs help from Rainbow Dash. Rainbow Dash reluctantly agrees, and finds herself bored throughout the entire thing.

That is, until Rumble, Thunderlane's little brother, asks Rainbow Dash to tell them a bedtime story. Obviously Rainbow Dash, not having any Daring Do books around, created the story from what she saw around her, and ends up creating a wonderful tale, not at all close to one needed to keep foals asleep.
