Nadine Flumberghast

is the imaginary friend of D.W. Read. She is an squirrel with white hair in three pigtails (although she is not old) and wears a blue dress. In contrast to D.W., Nadine is calm and soft-spoken. She often gives D.W. advice, though she rarely takes it, and she often only appears when D.W. is alone or when she thinks nobody is watching her. Judging by her size, her age is about the same as D.W.'s. She was introduced in D.W.'s Imaginary Friend in the series, although she appeared in D.W.'s Baby, which is a prequel to that segment.
