This is Dozys pony disguise! Just like her kids and Discord she makes up a pony disguise for going into pony towns so she attracts less attention. Her pony disguise is NOT the same as she looked before she turned into a draconequus, which is a point of soreness for her. She isn’t as good at making a convincing disguise as Discord or their kids and she can only hold it for just a few hours. Her tail remains long and prehensile. She’s also not able to get rid of her stripes, which manifest on her back legs. She usually magics up some leg warmers, which looks much more convincing.
