It is unknown as to what kind of species of rodent Grace is, since she has characteristics of both squirrels and chipmunks. She also has long-ears, which is a trait found on rabbits. It is possible that Grace is a crossbreed of several rodents that have evolved over the centuries. She has light tan fur with a large reddish-brown stripe, with two white stripes, running down from the top of her head, her back and tail.
Grace is seemingly friendly and gets along with Amy and her fellow messengers. She has shown to be carnivorous or at least omnivorous as she does eat meat.
