en Cuevana 3. The water sprite Toníček fell in love with the beautiful and hard-working Andulka, but her father did not approve, so he sent her to Prague to work as a servant. Toníček did not give up and went to look for her. All the water sprites from Prague and the surrounding area helped him, but Andulka was nowhere to be found. Of course, she was eventually found, but it was not easy.
