Kieselchen.

A pretty mouse, gray as a pebble, comes into money, builds herself a cabbage house and looks around for a man. As she likes to sing herself, she wants him to have a nice voice. She doesn't like sheep, frog and rooster, so she gives her favor to a tomcat. One day, when he gets to lick her blood, his appetite overcomes him. She manages to escape - and they have lived in enmity ever since.
