3rd Grade Male Rabbit is an unnamed third grader who made his first appearance in the episode "D.W., Dancing Queen". He appeared in the imaginary third grade classroom that Arthur was daydreaming about in the opening of the episode. In the dream Arthur imagined some of his friends as teachers. He also spoke when Brain activated the machine he invented, which transferred the information into the mind of all his students. He was the first one to speak and successfully answered the question. When the episode started he was seen right behind Binky in the cafeteria.
