But if resident animal expert Fluttershy can't tell them what it is, what are the fillies to do? Luckily, their new friend, Lilymoon, might have some hints from her studies before she came to Ponyville...if their strange dreams and bouts of sleeplessness don't put them off the case first. And when Princess Luna starts showing up in their nightmares, the Cutie Mark Crusaders know that something big is ahoof!
