She was a half pony changeling boy, but she mutated gender in her metamorphosis and became the subject of study and adoration by an aspiring endocrinologist.

I drew her in really standard form to really capture her figure and colors. She is an amazing skittlebug.

Also her right eye is pink. Her color scheme is a triad of blue, pink and yellow all about as far away in hue as can be, the only thing they have in common is being light and wispy. I coincidentally chose the colors of the pansexual flag, no intention, but it works.
