Dinky Doo

Dinky Doo is a female school-age Unicorn pony who lives in Ponyville. She has a light violet coat, yellow eyes and pale yellow mane and tail. Her mom is Derpy Hooves and her dad is Dr. Whooves. They conceived her on complete accident one estrus a few years back. Due to their bad parenting, she is half-homeless, staying at her parents' houses sometimes. Derpy treats Dinky more like a friend than her own daughter, showing affection and compassion but still not minding putting her in danger due to her own negligence and clumsiness. And Dr. Hooves just barely has time for her...whatever he spends it on. He doesn't even fully remember that he ever had a daughter, but if Dinky keeps insisting that she is, then he assumes it might be true. Due to her parents' negligence and disregard, she barely received any upbringing, making her seek attention from others. She is retarded, which makes it hard for her to understand complicated things, think logically or make good decisions. Sometimes she is unable to formulate her thoughts into words and sentences very well, ending up saying barely understandable or weird word constructions. She can spontaneously do something weird and irrelevant, like suddenly giggling out loud, sticking her tongue out, getting easily distracted, redirecting her attention elsewhere, et cetera. She also might have dysarthria, meaning her speech can be slowed or slurred sometimes. Despite her dire situation, she mostly remains happy and jolly, eager to meet new friends and engage in any kind of fun activities they may offer her. Like most other foals, she is adventurous, friendly, helpful, energetic and kind, even if she might seem stupid and undesirable for others sometimes. Her mom's influence is certainly there considering Dinky's clumsiness and awkwardness. Without many friends of her own, Dinky developed a rich imagination, imagining worlds of her own and even friends for herself whenever she feels lonely or bored again. It makes her very happy to receive attention from others though, but being in the center of it makes her anxious and panicky. Despite being a unicorn, she doesn't know how to perform spells or any kind of magic. She doesn't OFFICIALLY go to school, but she sometimes pretends doing so, attending lessons and joining other foals on recesses. Miss Cheerilee always lets her stay, not wanting to upset the little filly. Despite just starting to learn basic maths thanks to Miss Cheerilee, she still can't even read. She mostly eats what the locals feed her out of pity and she considers it all very tasty. When nighttime comes around however, she either stays at the house of one of her parents, asks somepony in the town to let her in for the night or sleeps in the street.
