Sparity babs! The first two are their dracony twins and only biological children, while the rest were adopted. I see them being the type of couple who adopt kids because they want to give them homes and with Spike also being an adopted kid, it’d be something he’d really wish for kids who don’t have any family left/willing to take them in.

Their names are, from left to right: (Top Row) Sapphire “Sappy”, Sulfur “Sulfy”, Dandy, Dia, (Bottom Row) Grace, Yorick, Ruby

Dandy’s based on a tuxedo cat, Dia’s based on a chihuahua and Grace’s bird half is based on a pigeon while I’m still trying to figure out what her cat half is based on.

Some more info below👇

• Sapphire and Sulfur have an interesting story for their birth. Rarity was pregnant as ponies usuly are when they’re expecting, but had given birth to two eggs after five months and then those eggs hatched after six months (I’m going with the headcanon that ponies gestate the way horses do irl)
• After the birth of Sapphire and Sulfur, Rarity was unsure if she wanted to go through the whole pregnancy and birthing process once again, but was conflicted since she and Spike still wanted a huge family. After talking about it, with Spike mentioning how being raised by Twilight’s family was the best thing he ever had and that he was also loved and cared for by Night Light and Velvet, they decided to adopt.
• Yorick is a yakallo, or a yak-buffalo hybrid, having been born out of wedlock. His parents were forced by their families to give him up, which is how he ended up in a orphanage.
• Dandy is one of many Abyssinian orphans who were left to fend for themselves after the kingdom fell into ruin due to the Storm King’s takeover. His parents had died from an illness they contracted. Because Rarity and Spike adopting him gave him a much better life than many of his peers could hope, he’s extremely grateful towards his adoptive parents and the second most affectionate with them.
• The kids usually spend more time with Spike, who finds himself often staying home and being the homemaker, as his busyness as Friendship Ambassador has lessened a bit over the years.
• Dia, Grace, and Yorick all came from the Canterlot orphanage and were an inseperable trio. Spike and Rarity initially wanted to just adopt Dia, but they saw the close bond she had with her friends and noticed how the griffon and yakallo were bullied and treated poorly by the prejudiced Canterlot natives who would come to the orphanage to adopt. Being unable to stand seeing them mistreated, they also decided to adopt them, which led to the trio profusely thanking them and promising they’ll help around the house. Not that the kiddos had to, the couple were just happy to have new additions to their family.
• Ruby was a fairly late addition to the family, being taken in by the family by the time her siblings were teens or pre-teens.
• Ruby’s egg was discovered in Ponyville, having washed up on a riverbank and found by Pinkie. The Ponk initially wanted to make it into an omelette until Fluttershy recognized that it was a dragon egg and stopped her before a disaster could happen. The Mane Six met up again to discuss the egg, Rarity volunteered to care for it with spike, and that was how Ruby was added to their family.
• Sapphire and Sulfur are very protective of their younger siblings, not hesitating to stand up for them if anyone were to treat them badly, especially if it was rooted in prejudice.
• Ruby’s very affectionate with her parents, always nuzzling and cuddling with them, something that they both will not hesitate to return. Rarity especially likes it since her daughter’s very warm to hug.
• When they were still very little and trying to get the hang of using their wings, Sapphire and Grace would regularly go on practice flights with their dad, who knew how difficult it could be to get the hang of flying. Even after they mastered flying now, they still regularly go on flights to spend time with Spike, usually doing so at sunset. When Ruby joined the family, she was included in these flights.
• Dia and Dandy love helping Rarity with her seamstress work, often by suggesting what accessories or details she could add. They, especially Dia, will even go gem hunting with their mom both so they have something to add to clothes or as treat for Spike and Ruby.
