Twinkle is a little girl, who lives on the North Dakota prairie.
Though her age is not certain, she appears to be about seven years old. She is a pretty girl, with rosy cheeks and long, fluffy hair, often tied back with a bow. She is tall and slender for her age. She wears calico and gingham dresses with matching sunbonnets. ("Prairie-Dog Town")
Twinkle's father is a farmer, and her mother a farmer's wife; they live close enough to the tiny town of Edgeley so that Twinkle can walk to school there. She has a knack for experiencing adventures among fairies and talking animals. (The Twinkle Tales)
