The hippopotami were playing together, floundering in the shallow water, and the noise they made prevented their hearing the stealthy approach of their enemies.
"You take the one nearest shore, Frank, I will take the other.

The guns flashed at the same moment, and as if struck by lightning the hippopotami fell in the stream.
