Its a good old fashion dare war between the Cutie Mark Crusaders. They were bored one day and Apple Bloom and Scootaloo got into a fight about who would wuss out on a dare first, so the idea was thrown down by Sweetie. The three of them put their name in a hat and drew a random name. You would get to propose a dare to the pony whose name that you drew.
Scootaloo drew Apple Bloom.
Apple Bloom drew Sweetie Belle.
Sweetie Belle drew Scootaloo.
The names have been drawn, and Apple Blooms dare came first. To pants their teacher in the middle of class. As you can see, she did so with gusto and a nice bow to top it off. What other shenanigans will come out of this war? The answer to that question will have to wait till another day.
