This story is a sequel to Magic Ears
The CMC is Ponyville's premier problem-solving organization. Though it consists of only three young mares, they rarely fail and their skills are a valued asset to Princess Twilight Sparkle. When Sweetie Belle, Scootaloo, and Apple Bloom are sent to Canterlot on what seems to be a routine, if high-profile, assignment, an unfounded urban legend will turn out to be a very real (and unique) quarry.
