Miss Sweetwater

Miss Sweetwater is one of the 3rd Grade teachers at Lakewood Elementary. Miss Sweetwater is a commonly-seen teacher at Lakewood who loves to do fun things with her students. She is often seen playing her guitar and passing out snacks to the class if they do well at their lessons.

Her homework is also known to be rather easy, unlike Mr. Ratburn's. However, she often teaches things that her students should already know at the 3rd Grade level, and compared to Mr. Ratburn, seems more interested in doing fun things than actual teaching.

Miss Sweetwater once served as a substitute for Arthur's class when their earlier substitute, Ms. Blank, was unable to come. She let them color and have snacks all day while she was the substitute, much to the class's delight.

Physical appearance
Miss Sweetwater is a tall rabbit with white fur and neck-length brown hair. She is always seen wearing a turquoise blazer and skirt with brown shoes. In the early Arthur books, she is depicted as a cat and wore glasses, although the cartoon and later books changed her appearance to that of a rabbit and removed the glasses.

Personality
Miss Sweetwater is, as her name implies, a very sweet woman who loves to have fun all day. She likes to sing songs, give snacks and treats to her students, and often does puppet shows or plays the guitar. She does not have a bad temper at all, and gets along with everybody in the school. But she can be a bit pesky and aloof, once scaring off the secretary Ms. Tingley when she insisted on playing a guitar solo in the episode Draw! in order to brighten her mood, and chased her all around the school.

Miss Sweetwater may be unfocused, however, as she rarely is ever seen teaching truly serious lessons to her students, and is not much of a challenge when compared to Mr. Ratburn.
