And yes another masterpiece from SPOILER ALERT!!!In Equestria Girls is pretty much clear that the human Pinkie Pie knows about the pony world, and the pony Pinkie Pie knows about the human world.My theory is that Pinkie is pretty much a guardian of the Multiverse, she doesn't "break the 4th wall" she just travels through the universes, in one universe Pinkie is a human, in other a pony, a spider, a reptil, a toaster, an alien....... she's everywhere at any time keeping the balance in the multiverse, avoiding the entropy. So Pinkie Pie is more powerful than Thanos, Galactus, Imperiex and even Squirrel Girl.Pinkie Pie is just behind you.
