Yes. As you've likely seen from my profile description, I love MLP. It's one of my favorite shows, and just like a lot of my other favorite shows, I have a few OC ideas for it. Here's three of them:

  They're a trio consisting of an Earth pony, a Pegasus, and a Unicorn. Their names are Snickerdoodle, Crash Lander, and Healing Hoof. All three of them are the biological siblings of an Earth Pony mare (named Cookie Dough) and a Pegasus stallion (named Cotton Wrap). 

  Snickerdoodle is the Earth Pony mare and the oldest sibling at 16 years old. As such, she's highly (sometimes overly) protective of her little sibs. When some creature says something nasty  about one (or both) of them, or they're in trouble, you can bet she'll be the first to come to their defense. She's also a talented young baker, and when she's not at school or hanging out with her friends, she's working as her mom's baking assistant. 

  Despite this, she's definitely not all business and protection. She also has a kind and caring heart, sweet tooth, and sense of humor that could give Pinkie Pie a run for her bits. Need some cheering up? Her sweet treats and jokes (which are just as sweet) are almost guaranteed to do the trick! Don't believe me? Just ask Lander or Healy! She does try to eschew her humorous side around older friends and adults so they don't see her as "immature," but all too often, something happens that's so funny that she just can't help but laugh!

  Crash Lander (or simply Lander, as his friends and family call him) is a young adolescent Pegasus colt and the middle child of the family at 13 years old. However, he was born with a backwards wing, which makes him an incredibly clumsy flier. This has caused him to be teased and picked on by his Pegasi and have some pretty low self-esteem. The story behind his name is that when he was just a little (well, littler) foal and was trying to fly for the very first time, he wound up crashing into a tree. When he tried to fly his way out, he crashed onto the ground.

  However, this doesn't mean that the young colt has given up hope. A little later in his life, he decided that if he couldn't be a strong flier, then he'd try to be strong in another way: the Earth Pony way. He specializes in handling heavy loads, whether it be pulling a large cart or just some heavy lifting. He's also found another purpose for his wings; not only do they help with carrying things supported on his back, but they're also great for keeping the particularly large stuff from falling off.

  Last but not least is Healing Hoof (or simply Healy for short). She's a Unicorn filly and the youngest of her siblings at only 7 years old. Due to her young, tender age, she's quite trusting and ingenuous. She pretty much has perpetual stars in her eyes, and it's pretty easy to get her to believe something (this has been her undoing more times than she can keep count of). Despite this, this little filly's got a heart of gold and is extremely empathetic towards others.

  Healy's young age and naïveté also means that she looks up to a lot of ponies, those ponies being: both of her older siblings, Princess Twilight Sparkle, Fluttershy, and her dad. When she's not going to school or playing with her friends or hanging out with her older siblings, she can frequently be found with her dad in his doctor's office. There, she's either working as his little nurse helper, hearing his stories about hospital phenomena and medical stories, or taking notes about being a doctor so that she can grow up to be one. She also likes to learn about magic and friendship so that she can grow up to be like Princess Twilight Sparkle.

  Now for their character designs. Snickerdoodle has a relatively average build for a pony her age, but she is slightly chubby. She's pretty embarrassed about this, but her mom tells her not to worry because "[she] used to be pretty plump when [she] was [Snickerdoodle's] age." That aside, Snickerdoodle also has a cream-colored coat covered in cinnamon brown freckles and a cinnamon brown mane, which she keeps held up in a ponytail (no pun intended) with a pastel pink bow. She also has pastel blue eyes. Her cutie mark consists of three snickerdoodle cookies with different, emoji-like faces: one has a serious yet confident smile, another has a cute and silly smile, and the third one has a nervous and insecure expression. They all form the shape of a triangle, and whichever face is on the top depends on Snickerdoodle's attitude at the time.

  In terms of physical build, Crash Lander is about as scrawny and gangly-looking as one would expect a pony his age to be, but don't let that fool you; this colt can carry quite a load! His wings are also kinda bigger than other Pegasi his age. Basically, his physique is a lot like that of young Fluttershy, but with somewhat larger wings.

  As for the rest of him, his eyes are a light navy blue, and his coat is rust-colored. His mane is a light teal color and usually pretty messy and unkempt. His cutie mark is a cloud blue pulley system with a large, heavy crate with a lightning bolt on it.

  Healy's physical build is exactly what one would expect from a filly her age. She has bright ocean blue eyes, along with a cotton candy blue-colored coat and a hazelnut-colored and light blue-streaked mane styled in a braid with a purple bow (and a long-and-loose matching tail). Whenever she's being "Daddy's Little Nurse," she wears a pink cross nurse's hat. She starts out not having her cutie mark, but I think that when she does get it, it'll be a light pink heart with golden yellow bandages wrapped around it and a golden yellow gleam star from the bandages.

  Now I know what you're all thinking (or maybe I don't): "Gee, three siblings that are so vastly different in pony type and personality? I wonder how they get along with one another!" Well, if you are thinking that (which is highly unlikely), then wonder no longer, 'cause I'm gonna go over that!

  Snickerdoodle feels that as the oldest of the siblings, it's her duty to look for her younger sibs no matter what, whether it's keeping them out of danger or letting them cry on her shoulder. Lander appreciates it and knows that she means well, but he often feels like his older sis takes it a little too far, and this often causes them to get into arguments. 

  Despite Lander being the middle child, he's ironically the one who gets doted on almost constantly (partially due to his wing disability). His mom and sisters are also the only characters who call him "Landy," which he finds a little bit embarrassing. Like Snickerdoodle, Lander is also pretty protective of Healy, except he tries not to overdo it, and he usually just does it when Snickerdoodle isn't around.

  As for Healy, she really admires both of her older sibs and thinks very highly of them. She views Snickerdoodle as "an awesome baker who's really funny, always there for [her], and super-cool and super-sweet like fruit punch ice cream." She also thinks that Lander is really cool because "he's got so much awesome super strength and super willpower that he could probably win a fight against Saddle Rager." Not that she would ever actually try to make that happen. That being said, she still finds Snickerdoodle really scary when she's angry and feels just awful about Lander's wing problem.

  So yeah, that's my my MLP OC description in this book. Believe me, there are plenty more yet to come. So anyway, what do you guys think of these Saddle Sibs? Do you think that my idea for Healy's future cutie mark is a good one, or do you have some better ideas? Please let me know your opinions in the comments below!
