I’ve been wanting to redesign these two for ages tbh. I was never that happy with Sparkler’s colors and I had designed Snow Belle before I really figured out her personality. So I tweaked them a bit, to make Belle more sporty and spunky (also swapped out her back paws for hooves and her unicorn tail for a cat one) and gave Sparkler tuxedo coloring! And also a scarf, since she likes making clothes with her mom.  
 
 
Here’s their updated bio info:  
 
 
Name: Sparkler  
Nickname: Sparky (Capper’s really the only one who calls her this), Sparks  
Age: Teenager  
Pronouns: She/her  
Parents: Capper Dapperpaws and Rarity  
Bio: Rarity and Capper’s adopted daughter! They spent quite a few arduous years filling out all the correct paperwork and doing interviews but they were finally able to adopt their daughter Sparkler as a very young kitten. Rarity was overwhelmed with joy at finally being able to hold her daughter, and spent the next few weeks bursting into happy tears every time Sparkler purred beside her. Sparkler discovered very early on that she preferred being a girl over a boy, as she was initially gendered, and her parents happily accepted her change in pronouns (Rarity took to it without any trouble, but Capper does tend to trip up now and then much to his embarrassment). Sparkler is spunky, cheerful, and down to earth; she enjoys sewing clothes with her mother, though she doesn’t have as much interest in trying the outfits on herself. She and Rain Shower (Fluttershy and Rainbow Dash’s son) have been friends ever since they started at Twilight’s school, because she was never interested in fawning over him like many of the other students. She has a big unrequited crush on Bowtie, Pinkie and Cheese’s son and Rarity’s Canterlot assistant, that she enjoys sighing dramatically over a tall glass of milk at the end of the day.  
 
Name: Snow Belle  
Nickname: Snow Ball, Belle  
Age: Child  
Pronouns: She/her  
Parents: Capper Dapperpaws and Rarity  
Cutie Mark: Athletics  
Bio: Capper and Rarity’s little surprise kitten. They had no idea that they were biologically able to conceive, having briefly talked to a doctor who shot down any possibility of it happening. Yet low and behold when Sparkler was around 5, Rarity realized she was pregnant. It was a hard pregnancy and Snow Belle was born very fragile and weak, having to spend the first months of her life in the hospital. As she grew older though, she was actually very outdoorsy and athletic. She has a cheerful outward disposition, but suffers from pretty severe anxiety. She desperately wants to be accepted by everyone and tends to use her sports prowess as a way to endear herself to the other ponies at her school (though she just as often uses sports as comforting stress relief; can’t have an anxiety attack about everyone hating you if you run so many laps you pass out). She loves sports of any kind, but has a particular fondness for tennis and gymnastics. Snow Belle’s horn is very undersized and the only magic it can do is glow and pick up objects. It serves her well enough in sports so it’s underpowered aspects don’t bother her much. She’s good friends Clover (Soarin and Applejack’s youngest daughter), Silver, and Ruby (Gabi and Spike’s kids) and they have a pretty tight nit group. She and Silver are especially close, with very clear crushes on each other. Ruby and Clover are disgusted with this.  
 
Relationships with each other: Sparkler and Snow Belle are very close, though Sparkler wasn’t sure what to make of her at first. First she was worried that Snow Belle would take all of her parents attention away, but then she just never showed up! After quite some time in the hospital, Sparkler was finally allowed to visit her little sister and her first thought upon seeing the undersized kitten was “I would kill a man for you”. Snow Belle idolizes her older sister, but sometimes to the point of not wanting to bother her with her fears and anxieties.  
 
Relationships with their parents: Their whole family unit is very close as a whole! Sparkler and Rarity are especially close, sharing a love of gossip and clothes making. Snow Belle and Capper love to race through Everfree Forest and he’s very proud of her athletic abilities. Capper understands how his daughters sometimes feel like outsiders and does his best to support them in any way he can. Rarity can and will fight other parents at Parent Teacher meetings if they turn their noses up at her kids.
