My Little Pony: Friendship Is Magic Vol. 18
It's the anniversary of the founding of Ponyville-which means it's time for a celebration! With a surprise show in store for Mayor Mare, it's up to Twilight and Apple Bloom to keep the festivities a secret... but that might be hard in a town like Ponyville, where you never know who might show up! Then, roll a natural 20 as Pinkie Pie and the rest of your favorite ponies get ready for a live-action role playing game for the ages! With elaborate costumes, captured princes, and one of Pinkie's famous cakes on the line, you can bet things are going to get crazy!
