3rd Grade Male Rabbit is an unnamed character that is seen in the lunchroom, playground, and Miss Sweetwater's class. He has had only one speaking role, which was at the end of the episode Arthur's Substitute Teacher Trouble where he remarked that he felt bad for the kids in Mr. Ratburn's class. He is used as a background character just like many of the unnamed characters and some named minor characters and is often seen hanging out with minor characters along with the main characters.

Appearance
3rd Grade Male Rabbit is a tanned rabbit that wears a faded purple collared sweater black pants with a belt, and red and white shoes. He also has some hair on his head. He also wears light blue swim trunks. In the episode Bugged this character was seen wearing glasses. It's unknown if he still wears them, but this is probably unlikely since this was seen in Brain's imagination.
