Smurfmouse is one of the Smurfettes who inhabited Smurfy Grove and was introduced in "The Crow In Smurfy Grove". Like the other Grove inhabitants, Smurfmouse wears the sand colored clothing, and a purple flower in her hat and has long hair that also covering her eyes. Smurfmouse's hat is bent at the point due to being near-sighted, which causes her to bump into things.
In the story, Smurfblossom helps her up after having bumped into the laundry line. She tells Smurfblossom that she doesn't wear glasses because she doesn't want to look like Brainy Smurf. After the suggestion of the Crow, Smurfmouse agrees to get a haircut, which she likes as it allows her to see better. However, she continues to bump into things.
