Librivox: Sammie and Susie Littletail by Garis, Howard R.

Summary: Once upon a time there lived in a small house built underneath the ground two curious little folk, with their father, their mother, their uncle and Jane Fuzzy-Wuzzy. Jane Fuzzy-Wuzzy was the nurse, hired girl and cook, all in one, and the reason she had such a funny name was because she was a funny cook. She had long hair, a sharp nose, a very long tail and the brightest eyes you ever saw. She could stay under water a long time, and was a fine swimmer. In fact, Jane Fuzzy-Wuzzy was a big muskrat, and the family she worked for was almost as strange as she was. (excerpt from text)
