W.D. is tomboyish and likes racecars and broccoli, and doesn't believe in unicorns. She has an imaginary friend who is an elephant named Maxine, who gives her advice.
One personality trait she has in common with D.W. is a dislike for being called by her full name.
W.D. is a bear with a tannish yellow complexion and short red hair. She wears an orange and tan shirt, blue jeans, a white and blue baseball cap, and white and red colored sneakers, but doesn't wear socks. W.D. also wears light blue pajamas. Being a bear, she has a heavier and somewhat more muscular appearance than D.W.
