It's the Feast of Foals, a celebration of misrule from Equestria's long ago past. Pranks are the norm, and who better to pull pranks than Pinkie Pie and her best friend Rainbow Dash? Only somethings not quite right this year. The pranks are getting a little mean...and in some cases, even a little deadly. When Rainbow Dash makes a confession to Twilight Sparkle, will the pair be able to put a stop to the reign of chaos in Ponyville?
