Рыбак на болоте встретил ЖЕНЩИНУ-ЖАБУ, которая попросила об одной услуге

Savely was a good fisherman. Not one who sits on the shore with a fishing rod for relaxation, but a true swamp fisherman. He knew where the tench swam, where the crucian carp lingered in the mud, where to set a weir, and where you shouldn't step because a hummock was only a hummock on top, and underneath was chest-deep water. He had a narrow dugout boat, old, blackened, but light. In it, he went where others wouldn't have dared even on foot.
