4th Grade Male Rabbit is an unnamed fourth grader at Lakewood Elementary School. He spoke once, during the episode Arthur Goes to Camp. Ever since that episode he has never been involved with any other episodes and was relegated to a background character. He is a member of the Tough Customers and has been seen sitting with them at the cafeteria but any further involvement is not known. His appearances in the show have significantly dwindled down, although he was recently seen in the episode Fifteen.
