Dorthia was a kitchen mouse, along with Jennie. Both were created by Nelvana for the Redwall TV series, never appearing in the book Redwall. Dorthia dresses and looks exactly like Jennie. Dorthia assisted Cornflower in making an inventory of the food supplies. Dorthia and Jennie also repair the Tapestry, as Methuselah died before it was recovered.
