Rodentia Ratburn

Rodentia Ratburn is Nigel Ratburn's sister. She appeared in the segment Arthur's Substitute Teacher Trouble as a substitute teacher for her brother when he was losing his voice. At first, Arthur and his friends were afraid her teaching skills might be more difficult than Mr. Ratburn's, due to being the strictest teacher at Lakewood Elementary School. However, after Miss Ratburn arrived into the classroom, her teaching skills turned out to be very simple, including the 1 X's tables, color combinations (such as yellow and blue make green), and puppetry. In the aftermath, Arthur and his friends proved her teaching skills were way too childish for everyone in the third grade, and her brother finally returned the next day. Subsequently, Miss Ratburn is no longer seen after that segment.
