|Book debut||D.W. Thinks Big|
|Voiced by||Susan Glover|
Jessica, Richard, and Cora stayed the night at Arthur's House to attend Aunt Lucy's wedding the next day. D.W. tried to put some makeup on Jessica's face, but accidentally gets it on her aunt's dress and Jessica shoos her out.
Jessica is an aardvark with a light tan complexion, short curly orange hair, and red lipstick. Although she is an aardvark, she has a Y-shaped rabbit's nose as opposed to two nostrils that aardvarks usually have. In the wedding she wears a dress that's the same color as Cora and the bridesmaids' dresses and high heels that match.
Jessica spoils her daughter. She assumed D.W. broke Cora's locket and took Cora's side again when she refused to search for the lost ring because her dress would get dirty.
However, she did show kindness and worry when D.W. entered the pipe organ, and agreed that Lucy make D.W. be the flower girl instead of Cora for getting the ring out.
