Cora

Cora is a cousin of Arthur, D.W. and Baby Kate. Her parents are Aunt Jessica and Uncle Richard.

Biography
Jessica, Richard, and Cora stayed the night at Arthur's house to attend Aunt Lucy's wedding the next day. Cora shows D.W. her locket that Aunt Lucy gave her, which she then accidentally breaks and blames D.W. She wore a special dress and crown for her job as the flower girl of the wedding. At the church, Cora yells at Arthur to smile but the distraction makes him lose his balance and throw the wedding ring into the air, landing in the piano's pipe organ. While Cora refused to retrieve the ring and get her dress dirty, D.W. successfully found it and Aunt Lucy decided to make D.W. the new flower girl and let her wear Cora's crown as a thank you for getting the wedding ring out of the pipe organ.

In Brain's dream where he was a bug, Cora was seen at Lakewood talking to Nancy.

When Grandma Thora was shopping for her birthday, she decided to buy Arthur the Mutant Muck Monster as a present.

Personality
Though she only appears once in the series, Cora is portrayed as being spoiled, annoying and rather rude to the Read family children, especially D.W., but acts like a little angel when the adults are around. Her bratty nature is later exposed at her aunt Lucy's wedding.

Physical appearance
Cora is an aardvark with a light brown complexion. She wears a blue short sleeved dress with green stripes at the bottom and on her sleeves, long white socks, and red-and-white sneakers just like Arthur's sneakers. She has short brown curly hair. She wore a lavender dress with puffy sleeves, beige pantyhose and white shoes to the wedding since she was the flower girl.
