Sherry Goldsmith

Mary is a third grader in Miss Sweetwater's class at Lakewood Elementary.

The first time she spoke was in the episode, "Arthur's Substitute Teacher Trouble" as she spoke to one of her classmates and most likely friends, 3rd Grade Male Dog about the clouds in the sky. The second time she spoke was in the episode, "Buster Baxter, Cat Saver" and the third time took place in the episode, "Arthur and the Square Dance" when she said "Whoahh!" during the square dance at the school as she and the entire class fell to the ground, and the fourth time in "The Lousy Week". She is relatively a nice student as seen in many episodes.
