This might be a little out there, but I believe that there were two Pinkie clones in this episode,
There's the obvious Pinkie clone the one in the Fedora. How ever dose anyone recal the ponies in the dance club one had a uncanny resemblance to a certain pink party pony.
The mane body and eye color are all a exact match to Pinkies. Perhaps a clone changed it's identity and tried to blind into the population of Manehattan?
