Of the Mane 6 Pinkie Pie is my favorite so I figured she’d be the best choice to help me with a reveal.  
The Ku-neigh-ichi’s main strategy revolves around kicking up as much confusion as possible and since they all look alike and are really fast it gives the impression that there’s even more of them. How do they do it though, the odds of finding that many ponies with the same mane, coat, and eye color are astronomical. Simple, magic. The hoods they wear are enchanted with an illusion spell that changes the wearers appearance, though it doesn’t affect body shape, height, or clothes. Not much else to say, well other than that it’s surprisingly tricky to make a pony do a sweep kick.  
I don’t own Pinkie Pie just this pic
