Her design is hard to come up with because I want her to be lively and pastel like, to give people impression of she is friendly and nice. I imagine her like cute stuff so that’s why she has cute tie and poofy skirt. I also threw quite a lot of pastel blue and pastel yellow because of her cutie mark.
Her species is dutch rabbit that is commonly used for pets. Rabbit likes to snuggle with the owner and Pinkie likes to give hugs for people around her. Dutch rabbit is friendly and intelligent and approachable too, and obviously sociable and energetic.
