A strange sickness has infected nearly everyone in Ponyville. It seems there is no hope for a cure - until Twilight stumbles across a strange blue box...

Twilight had several analogies she liked to use to describe the difficulty of saying no to rarity, her favorite of which was "Imagine trying to flag down a train in the middle of the night while painted black...by jumping in front of it"

One peaceful spa trip with your friends isn't too much to ask, right?
Not when you're Twilight Sparkle......and definitely not when you're the Doctor's newest companion.
So when Zecora finds what appears to be a parisprite in the Everfree forest, but is actually something much, much worse, they have to race to make sure these parasitic creatures don't destroy Ponyville, or Equestria......or the world.
But of course nothing is that simple...... Twilight desperately wants to keep her friends out of the line of danger, but with Rarity playing matchmaker, Rainbow Dash playing spy, and Pinkie Pie being, well....Pinkie Pie, it's going to be a harder task than she thought.
Sequel to :The Changeling Princess

The left wall of Sugarcube corner had been nearly completely demolished by the box, and it was a testament to the skill of the earth-ponies who had constructed the building that it was still standing at all. She shook her head and went to examine the words at the top of the thing that had caused all the havoc.
"Police public call box" she murmured softly, eyes almost glowing with curiosity

Twilight Sparkle is planning on having a relaxing day, but that all changes when a blue police box crashes into Sugarcube corner. Now Twilight, Pinkie, and a strange stallion named the Doctor have to try to save Equestria from a threat disguised as their own beloved ruler.
