Those with protruding foreheads found something downstream. They cupped it in their hands, sniffed it, called to their companions. It was a fish. But not an ordinary fish. Its belly was grotesquely swollen, its eyes clouded.
The one watched from atop a rock, observing what was happening in the distance. It could not understand what those beings were doing. Only that they moved differently than usual. They seemed agitated.
The river water began to turn murky. At first it was a pale brown, but grew darker as time passed. Something was happening upstream. It was not raining. Yet for the water to turn such a color was strange.
The four companions had noticed too. One tried to approach the river, but another grasped its arm and stopped it. They sensed danger.
From beyond the mountains came a sound like a low growling. The ground seemed to tremble. Too loud for animal footsteps. Too long for thunder.
The one stood up. The companions did the same. All looked in the same direction. Toward where the sound came from.
The river's water level began to rise. Muddy water spilled over the banks, seeping into the grassland. The protruding-foreheaded ones downstream began running toward higher ground.
Seeing them run, the one understood. They had to flee.
The sound grew louder. From beyond the mountains appeared a wall of brown water. Swallowing trees and stones together, it rushed toward them.
The five ran. Their legs nearly tangling, they scrambled up the rocky slope. Their breath gave out. Their chests ached. Still they did not stop.
The water swallowed everything. The place where they had been moments before, the thickets where they always searched for food, the hollow where they rested at night—all vanished. The brown torrent swept away memories along with everything else.
Looking down from the high rock, they could see other groups. The protruding-foreheaded ones, the short sturdy ones—all had fled to high places the same way. Though different species, their flight from water looked the same.
A day passed. The water did not recede. Their bellies rumbled. Their mouths grew parched. Still they could not descend from the rock.
The protruding-foreheaded ones on distant rocks waved their hands. The one waved back. They could not understand each other's words. But they understood they shared the same situation.
Night came. The sound of water did not cease. In the darkness came the sound of things colliding. Perhaps large trees flowing past, perhaps rocks tumbling—they could not see.
At dawn, one of the companions had stopped moving. It was breathing. But would not open its eyes. It had drunk nothing since yesterday. Its body might be nearing its limits.
The water began to recede gradually. But it would take much longer for it to withdraw completely. During that time, two companions became motionless.
When they descended from the rock, their feet sank into mud. The familiar landscape had all changed. They felt as though they stood in an unknown place.
Dead fish lay scattered in the mud. Birds too, small beasts too—all had stopped moving the same way. The world after the water withdrew was filled with the smell of death.
The protruding-foreheaded ones on distant rocks also descended slowly. Their numbers had decreased. Like this group, they had lost someone.
The one knelt on the muddy ground. It had always drunk water here. Always tried to catch fish here. But now, nothing remained.
The two motionless companions were still breathing. But could not rise. Left like this, they might die.
It began walking. Just the three of them. Carrying the two motionless ones. To search for new water.
The water changed everything.
Still it continued.
