Edith Bycenko

Ava Schweiffer is in third grader who made her first appearance in the episode "Arthur's Eyes". She has spoken numerous times in a number of episodes.

The first time she spoke was in the episode "Arthur's Spelling Trubble" where she misspelled a word during the spelling bee. She spoke again in the episode "Arthur Bounces Back" where she and a few other girls saw Arthur's kissing booth.

In the episode "Vomitrocious", she was part of the kids that were making fun of George over the fact George had a bloody nose, but that event with George has since faded away. Despite that episode with George, she gets along with the other kids.

Description
3rd Grade Female Cat is a cat with a tan complexion. She wears a white collared blouse, a pinkish-red skirt with front pockets, a tan belt with a yellow belt buckle, long pink socks, and brown shoes. She also has short dark brownish-red hair in the form of a bowl haircut.

Personality
Her personality is not known, since she is a background character, but she appears to be nice to other kids.

She is probably a good speller, having made it to the school Spell-a-Thon. She plays the piccolo in the Lakewood Elementary Band, and was part of the ventriloquism craze George started with her moose puppet.

Trivia

 * This character is in Miss Sweetwater's class.
 * Strangely this character has a bowl cut, which is an unusual hairstyle for girls as boys are more likely to have that type of hairstyle.
 * Even though she is nice to other kids in the background, she was mean to Arthur and George by laughing at Arthur's kissing booth and George's nose bleeds.
