Nadine is D.W.'s imaginary friend. She portrays D.W.'s conscience, and usually appears when D.W. feels guilty, scared, or angry. She is 5 years old. Both girls are aware that Nadine is imaginary, since only D.W. sees her (also babys,pets and other imagenary friends such as the tibble twins and Vicita imagenary friends) . One episode shows D.W. with her when she's much older, while another shows that D.W. does not need Nadine as much as she used to. She has long platinum blonde hair styled exotically in three pigtails and small buck teeth. She can create imaginary items and they can appear/disappear with magic.
