Lotsa apples! Just like Pinkie, Applejack has multiple partners in my headcanon, these being Trenderhoof, Coloratura, and Soarin. Couldn’t decide who between those three to ship her with, especially since I aready had designs for some of these babies and didn’t wanna scrap them, so I thought “why not all?” The leftmost column are Trenderhoof’s kids, the middle column are Rara’s kids, and the rightmost column are Soarin’s kids. Their names, from top to bottom are: (leftmost) Pippin Apple, Gala Apple, Apple “Corey” Core, (middle) Crispin, Merry, Goldie, (rightmost) Airizona “Airy” Apple, Snow Apple, and Flapjack. Also, these were the first siblings I finished designing, and now they’ll be the last of the Mane Six kids I’m showing. Ah, irony.

Some more info below👇

• Pippin, Crispin, and Airy were triplets conceived via one of Cadance’s spells and carried by AJ. The rest were carried by her spouses since they wanted to give her a rest from the pregnancy, with Trend and Soarin even undergoing genderbending spells.
• Unlike his fellow triplets, Pippin has a lankier build, something he has in common with his father. Make no mistake though, he’s still inherited some of that Earth pony strength, with others often being surprised that he can lift things (and creatures) far heavier than him.
• Crispin is the oldest of the triplets, but is often mistaken as the youngest since he’s shorter than Airy and Pippin.
• Gala and Corey have a hard time getting along, mainly because Gala is constantly busy and prefers to be left alone as she works while Corey often seeks out playmates in his siblings and goes to his full-sister first since they’re often the ones left at Sweet Apple Acres.
• Snow Apple is often compared to his grandmothers, Pear Butter and Cumula (Soarin’s mom) because of his similarities to them in both appearance and personality. He inherited his Pear Butter’s eye color and his coat color is closer to that of Cumula’s. Also like Pear Butter, he shows some interest in baking while having a similar energetic enthusiasm like Cumula.
  
• Flapjack and Corey are very close, being the youngest of the family with Corey having been born two years before his half-sister. Whenever they’re together, they’re often mistaken to be full-siblings due to their similar coat and mane colors.
• Rara’s family has a history of twins and triplets, so she believes that it influenced the spell used to conceive the triplets and the fact that she later bore Crispin’s full-sisters who are twins. The fact that Merry and Goldie have even been described as somewhat resembling their twin uncles, Rara’s younger brothers, makes it quite likely.
• Flapjack was named after Soarin’s cravings while he was pregnant with her, the fact she even has similar colors to a flapjack amuses her parents.
• Gala apprentices under Rarity, showing promise in her seamstress skills, and it comes in handy since she’s rather good at making clothes that are comfortable but still give protection during hard labor. In fact, her relatives even wear some of the clothes she makes while doing farm chores.
• The kids take turns tending to Pear Butter and Bright Mac’s trees, but none of them take that duty as seriously as Corey, who always checks on them and even lists things he would have to do to maintain them. Snow Apple is best friends with Sweet Apple (Big Mac and Sugar Belle’s son in the finale) and Lil’ Cheese, the three of them having been playmates when they were little and still often hanging out when they got older.
• Flapjack’s rather conflicted on what she wants to do when she’s older, since she both aspires to be a Wonderbolt like her dad and enjoys making deliveries for her family. So much like Rumble, she’s scared that once she gets her cutiemark, she would have no choice but to choose between those two passions.
• Airy likes making trips to Manehattan at least twice a year, since it gives him the opportunity to visit extended relatives on both of his birth parent’s sides. This is because aside from his Orange cousins residing there, Soarin’s parents also moved there for retirement.
