The Merman's Children.
The merman Vanimen stays with Father Tomislav in the zadruga which is a small hamlet with cultivated fields but surrounded by forest, a day's journey from Skradin. The villagers farm, cut timber, burn charcoal, hunt and trap. Their thatched, wooden, one- or two-roomed, houses stand above the ground with animal stalls below. Also:
"Granaries stood about, small, slat-sided, elevated on skinny boles whose roots made birdlike feet, as on Baba Yaga's famous abode." (p. 118)
Baba Yaga's abode appears in Neil Gaiman's The Sandman. See image. Also, in Gaiman's The Books Of Magic, Tim Hunter, who resembles and parallels Harry Potter (see here), escapes from Baba Yaga by tripping her mobile house and making it fall.
