Peepers is the cute and beautiful girlfriend of Snipes and one of the supporting characters in Rock-a-Doodle. She was voiced by Sandy Duncan, who also voiced Vixey from The Fox and the Hound (the last Disney film Don Bluth worked on) and Queen Uberta in The Swan Princess (directed by Richard Rich, the same director of The Fox and the Hound).
Peepers is a mouse. Because of this, she is initially terrified of Edmond, but he tries to convince everyone that he used to be a boy. It is not until the very end of the movie that she believes him and comments "He was a little boy.... oh, he was a handsome little boy..." She has a lisp and very round glasses and is constantly arguing with Snipe's chauvinistic views.
