Whirlpools

Thereupon the little mermaid left the garden and went toward the roaring whirlpools at the back of which the witch lived.

No flowers grew there, no seaweed, only the bare gray sands, stretched toward the whirlpools, which like rushing millwheels swirled round, dragging everything that came within reach down to the depths.

Stay away from whirlpools.
