The Pinkie-Cheese Kids
Cheese and Pinkie married right after Applejack and Double married. A year or two later, they had the triplets, then, five years later, they had their youngest.

All the siblings play and bake and party together, and all of them are close.

Jovial
Age: 14 (TRIPLET TO JOY/JUBILEE)
Gender: Male

Bio:
Jovial, or Jove, as he is commonly called, is the oldest of the triplets by about 60 seconds. He isn’t the ringleader of the siblings, leaving that to Joy. At a young age, he began drawing and is one of the best artists in Ponyville. He taught himself because the Pie’s never had enough time to sign him up for art lessons. When he was 10, when the flu swept through Ponyville, he went around to all the different houses and taught several ponies how to paint. He got his cutie mark that night, a paintbrush with yellow paint.

Jove makes banners with his mother, teaches art lessons for free, and gives private lessons to Honeycrisp, AJ’s daughter, because she doesn’t like other ponies to see her awesome drawings (It makes her feel uncomfortable when they compliment her).

Jove is endlessly patient, good-natured, kind, and calm. When one of his sisters or Chipper gets worked up, he is always there to calm them down. When put in charge, he is a great leader, and always splits up the work evenly.

Jubilee
Age: 14 (TRIPLET TO JOY/JOVE)
Gender: Female

Bio:
Jubilee, called Ily, was the second to be born, beating Joy by 46 seconds. From a young age, she always helped Pinkie with baking, and learned some of Grannysmith’s secret recipes, which she guards fiercely. When she was almost 10, Rainbow Dash had a serious wing injury, and it was possible that she would lose her wing. RD became very depressed and began to give up, which increased the chances of her losing her wing. Ily and Joy secretly went around the whole of Ponyville and planned a huge feast. Everyone brought something that reminded them of Rainbow and did a 30 second talk on why. Ily baked most of the food, but several ponies also brought their own foods. The event made Rainbow feel 20% more wanted and loved then ever, and Joy and Ily both got their cutie marks when Rainbow made her thank you speech (or, as ‘speech’ as Rainbow can).

Jubilee (Ily) gives baking lessons to anypony who happens to show up that day, caters, and helps Pinkie bake. Her specialty is every food and drink you can imagine!

Ily is rather patient, loving, kind, cheerful, and wants to maybe open her own restaurant when she gets older next to Sugarcube Corner. She loves making up new ways to ambush her siblings with pies or ice cream bombs, and bounces on her bed a lot!

Joy
Age: 14 (TRIPLET TO JOVE/JUBILEE)
Gender: Female

Bio:
Joy is the youngest of the triplets, but she is the ringleader of all the Pie children. The triplets are BFFs, but NEVER leave out Chipper. Joy is rumored to be the next element of laughter. She is never seen without a smile, and has the same mysterious mane as Pinkie where anything can hide. When she was 7, she somehow managed to smuggle en entire barrel of cider from Sweet Apple Acres to a Party on the other side of Ponyville in her mane without missing a bounce. Pinkie cried with pride for an hour. Boneless 2 bounced.

At the same feast Jubilee (Ily) got her cutie mark, Joy got hers. Whenever somepony is sick or injured now, she goes with Zecora to their house to help cheer them up, may it be reading a book to them or doing magic tricks.

Joy is…well, joyful, happy, cheery, not-really patient, bouncy, and smiley. She is a good leader, sometimes helps Ily ambush their brothers with pies (when she isn’t ambushed), and loves ALL THE SEASONS!!!!

Chipper
Age: 8
Gender: Male

Bio:
Chipper, or Chip, is just as close to the triplets as they are with each other, but, from a young colt, he was always very shy and quiet. He was always cheerful, but going out in public made him nervous and talking in public??!! UNTHINKABLE!!!!!! Thankfully he’s mostly grown out of it. He can talk in public, but he still gets nervous, and he’s completely fine with walking around town. He’s not a popular pony at school, but none of the ‘cool’ ponies even notice him..usually, which is completely fine with Chip. He hasn’t gotten his cutie mark yet, but he is close friends with all of the CMC. He and Honeycrisp are pretty close since they’re both shy and she visits Sugarcube Corner every day for art lessons.

Chip has a very strong Pinkie-Cheesy Sense and can almost always avoid getting ambushed by his siblings, although not always. His sense is very mystical, and he sometimes goes to Twilight for help when he sees a particularly strong vision.

He is nervous, shy, kind, cheerful, a bit jumpy, and an expert bed bouncer, as declared by Joy and Ily.
