pegasisterslippers

Hello mlp forum! I recently was gifted these slippers, I am mostly a gen4 fan, but because these are officially mlp branded I was wondering if this is a pony from earlier generations that I don’t recognize? It looks like a gen 1 pony to me but I’m not an expert… I’ve tried looking around on the identification sites a bit but I’m a bit lost, to be honest. Are they named or is this just a random pony made for these slippers? Thank you in advance for your help with my curiosity! They seem to be a Pegasus with a white coat, a purple/blue sparkly mane, blue eyes, and a yellow star/sun as a cutie mark.
