Maryann

Maryann is a preschooler who made her first appearance in the episode "D.W. All Wet". She attends school at the Elwood City Preschool.

Her name was revealed in the episode So Long, Spanky. There is a chance Kyle might be her brother since they have the same dads as shown in the episodes "Bleep" and "Emily Swallows a Horse".

In "D.W.'s Very Bad Mood," she is invited to Lisa's party. Other than this, not much is known about her.

She screamed when Timmy snatched an apple juice box from her.

Physical appearance
Maryann is a dog with a cream complexion. She has short hair and wears a purple dress, a light lavender vest over her dress, and brown Mary Jane shoes.

Trivia

 * Maryann may have a brother named Kyle. She may also have an older brother.
 * During Career Day in "D.W. Aims High", she can be seen wearing a safari hat, which suggests that she may want to become an explorer when she grows up.
 * Maryann was shown with Fern in the episode Sue Ellen's Little Sister as Fern's little sister. Fern, from what we've seen and known, is most likely an only child. Plus Maryann's father is very different compared to Mr. Walters. However, they could be step-sisters or half-sisters.
