I got Pinfeather from MoccaBliss <3

Meet Beach Wave, the daughter of Sun Cloche and Caldera! Having been born to the couple shortly before they agreed that co-parenting without a relationship was the best way to go, Beach Wave still felt plenty of love from both parents. She grew up in a rather large family, having her father, mother, and her mother's girlfriend Burning Love and Love's husband Hidden Riddle. She adored every ounce of attention she received, usually putting on fashion shows for her guardians, which consisted of her wearing her mother's clothes and slathered in messy makeup. Beach Wave grew up to be a outwardly confident and bold mare, but privately holds herself to nearly impossible beauty standards. She is convinced that she must be a skinny, graceful, long-haired darling, which occasionally stifles her self-expression. Beach Wave focuses her energy on designing beach wear and accessories, and is hoping to soon be accepted into an internship with well-known fashion designer Rarity!

Meet Pinfeather, also known as Pigeon, the child of Burning Love and Hidden Riddle! Having been born only a few years later than Beach Wave, Pigeon was welcomed into the growing family with open arms and plenty of enthusiasm from their older sister Beachy, who's only goal was to use Pinfeather as a living doll. This led to Pigeon realizing from a young age that they didn't feel particularly strongly one way or the other when it came to gender expression, obviously used to being dressed up in both feminine and masculine ways depending on how Beach Wave was feeling that day. He is much less up-front than his sister, usually keeping his thoughts to himself and treading softly. Pigeon's talent lies in crafting, specifically pinned buttons and stickers, which he loves to sell at conventions and small fandom gatherings!
