The Pie sisters enroll at Canterlot High for their sophomore year, happy to get away from the constricting and conservative rock farm they lived on. Due to the eldest sisters worry about not being in control over every thing like she usually is, she convinces her sisters to become the brutes of the school so they don't get made fun of like in their old school. So, they do just that. Though it seems they get some friends along the way, and they decide to teach Limestone not to be so scared of not being in control. Problem solved... without the help of pony magic for once!

Sort of a parody of the Rainbow Rocks incident. But instead of the Sirens, it's the Pies with their lovely Pinkie Pie!
