nanny dafoel stood ahoof of her nemesis turned charge mare do well or as her freinds new her fluttershy when she heard the clattering sound from her entrance.
arriving in her hallway she was met with a blast of magic from the horn of a young colt and filly , it was twilight sparkle and her brother shining armor who had come to put a stop to nannies regression spree when they both spoke up "if we work together we can take her sister!" " on it!" they both joined horns and cast a spell at nanny dafoel who simply shrugged it off with a wry grin on her maw "why didnt it work?" she looked quizzicly at her brother only to see his helmet on the floor clattering away , he had been destroyed... or so she thought until she saw her brothers infantile form clattering about in the helmet his newly formed diaper allready filling out as he struggled to get out of the helmet.

by this point twilight was beyond reasoning "wha haf yoo done to my bwuvewr!" she yelled from her lofty position above nany dafoal ,thats when she realised it was too late and she would be joining her brother back in foal and fillydom soon enough as she sank down to the floor led formost by the weight of her newly appeared (and used) diaper.

nanny dafoel used her magic to lift the ponies into the nursery as she locked her door again and cleaned away the debris staying vigilant incase of visits from future would be rescuers
