Earth Ponies  
A newborn Earth Pony is generally larger then Unicorn and Pegasi. As they grow they getting bigger and stronger. The moust tall Earth Ponies can reach a height of Luna or even Celestia. They are omnivorous, but a lot of them still keep a relatively vegetarian or vegan diet. And they do keep livestock.  
Because of their connection to the earth they’ve been known to be the founders of many prosperous farming families and towns. All communities trusting them deeply.  
Female Earth Pony usually have from 3 to 5 foals. Their pregnancy is not so painful as Pegasi or Unicorns. Earth Ponies follow the lead of their family traditions over the centuries since the family was formed.  
Their magic is concentrated in their hooves, allowing them to feel the ground they walk. All Earth Ponies can influence on flora. They do this by channeling their magic diractly into roots. This ability explains why Earth Ponies are such accomplished farmers. Without Earth Ponies Equestria would starve. The foals can’t use their magic (which develops by itself in the meantime) until they’re 4 or 5 years old. That’s the same as Unicorns.  
They are the longest-lived unlike Unicorns and Pegasi.

Newborn  
Little Pinkie was much smaller, compared to her elder sisters. She was extremely frail and light, so picking her up was an action her family had to do in the most gentle way possible. The little filly often refused to have her milk, and this made the situation even worse: some doctors had even told her parents that, if she didn’t eat, she wouldn’t last more than a few months. Luckily, she survived, but since she started following the adults’ diet, she ate only when it was her eldest sister Maud who gave her the food. This complicated a bit everything, because Maud also had to help her father and sisters. Somehow, anyway, Pinkie Pie lived happily her foalhood, without knowing what was awaiting her.
 
Filly  
Her parents had started to argue more violently and the filly was suffering because of it and because of her sisters’ behaviour, as well. Once again, Maud was the only one who took care of her. She was forced to do backbreaking work dragging huge boulders. The result was more important to her parents, so they neglected her health and started using the whip. They hit so hard that it left a lot of scars on her back and after work they just left her exhausted on the ground. Pinkie was listening when her father said to her mother that he thought the pink filly was completely useless. The next day, Pinkie ran away and she was found by Mr. and Ms. Cake. They were stunned by the scars on her back and tried to help her in any way they could. They adopted her in and became her new family. Since then, Pinkies life was much more brighter and happier.
 
Teenager  
Pinkie was surrounded by care of her adopted parents. She learned to bake and made new friends every day. Now all Ponyville knows her as a cheerful pony despite her past. She did not care about her parents, she only sometimes visited her sisters in secret and brought them goodies and every time they were surprised at her skills in cooking. Then her “Pinkie Sense” began to appear more often. Pinkie decided to travel to study her ability and find good use for it and she certainly did not miss the opportunity to meet new ponies while she was traveling. After returning to Ponyville, she mastered her ability very well and told the Cakes that now the nearby towns now know about their shop. Since then, every traveler does not miss the opportunity to look into their store and enjoy pastries from Pinkie Pie herself.
 
Adult  
The Pinkie we know nowadays: the lively and playful pony who runs the bakery together with the Cakes. She’s the youngest of the Mane 6, but the one who had been hardened the most by her life. The fact that she’s one of the Elements of Harmony, friends with the Alicorn Princess, and that she saved Equestria more and more times made her quite famous: she travels almost everywhere due to the parties she’s asked to organize.
