It rolled like tumbleweed across the water's glassy surface. It mixed its colours; white and grey and sometimes just a pinch of green made it more formidable that it really was. It had stealth and trickery tucked inside and by the time it reached the shore, the thing that it concealed had splayed apart the fogginess and escaped along the foreshore. It lingered on the sandy lip, where the seaside kissed the sand. And when it turned to head back out to sea, it pulled the final strands of daylight with it, dragging out the light until it snapped itself in blackness.
