Just like last year, this is the day chosen for Megan Williams mainly because it was on this date that her character debuted. Until there is an official day, it will be this one. Nonetheless, this is the celebration of the original HiE even though it was known as Pony Land in the actual show. After seeing her omitted in a Tell Your Tale episode where a door showed what looked like something from Rescue at Midnight Castle with her not on it, this makes me feel that she is becoming forgotten and can really use some love. Other than that, let's celebrate this day.

To the one Real and cannon Human in Equestria (and her siblings as well).

It looks like Twilight and Spike came to celebrate with Megan on her special day.
