A brother and sister playing by the well are snatched by a Siren. The Siren makes the girl carry water in a bucket with no bottom, and makes the boy chop wood with a blunt ax. The children escape one Sunday while the Siren is at the local bath house. When the Siren realizes they are gone, she pursues them. The children throw a brush behind them that becomes a mountain of bristles, a comb that becomes a mountain of teeth, and a mirror that becomes a glass mountain.
The Siren dodges these items but can’t keep up, so the brother and sister are able to escape to their home.
