Steve

Steve is a fourth grader who made his first appearance in the episode Arthur's Eyes as a minor character. Not much is known about Steve other then he hangs out with both Billy and Buster in the episode Buster Makes the Grade. He most likely hangs out with other fourth graders along with third graders as shown in many episodes during and after Season 1.

His name was also revealed in the same episode when Buster told him and Billy that he can't play until he finished his homework, which was so surprising and if not shocking to the two fourth graders that they subsequently fainted from hearing what Buster had said to them.

He has spoken only once so far, which occurred during the first few minutes of the episode Love Notes for Muffy. He also has a younger sister named Maria who is always seen in Mr. Ratburn's third grade class along with most of the main characters of the show. Even though they are related, Steve and Maria are rarely seen together.

Even though that's the case they were together in the episodes Sue Ellen's Little Sister and Muffy's New Best Friend to name a few. The status of their relationship with each other is also unknown, but as seen in the few episodes they are together, they most likely get along with each other quite well.

Appearance
Steve is a rabbit with a beige complexion. He wears khakis, an orange shirt with a white collar, and blue and white sneakers. He also wears glasses. He was seen wearing red swim trunks in the episode D.W.'s Backpack Mishap and he also wears a green backpack.
