Given the original marketing angle of fluffies, I kinda have to wonder how deeply the MLP fgranchise is ingrained into their mindsets.

Do they try to scrawl friendship reports in crayon? If you were to walk by a feral herd and start whistling the theme song would they try to sing along? Maybe there were special story books and dvds that activated genetically implanted easter eggs allowing a fluffy pony to perform a new trick, read Equestrian or unlock information about the show and merchandise. Early fluffies might even have been convinced that they were MLP characters sent By the Princesses to live with humans.
