When she catches a bad case of pegapox, Rainbow Dash cannot fly up to her cloud home. Grounded and quarantined in Ponyville, she is taken in by Rarity and Sweetie Belle, who vow to nurse her back to health. Can the pegasus survive her well-meaning caregivers long enough for Twilight to find a cure--and why is the weather turning so weird?

But is this what Ponyland needs, or is it a Princess who just cannot let go? *starring the Original mane six, as they were intended to be*
