The Fluffle Puff Pony. A legendary equine that comes around only once every thousand years. And she lives in Twilight's library! Take a trip to Ponyville and see an average day in the life for the one, the only, the inexplicably fluffy, Fluffle Puff, as she fluffs, and she puffs, and she blows Ponyville down!
I in no way own Fluffle Puff or anything related to her. I am but a humble fan entranced by her antics.
