 What does the ocean consist of on this planet?
Safe from the scrutiny of brothers and parents, there was nothing now to stop him from going to the ocean. It was exactly as he knew it would be: the milky-orange stream had become motionless and its minute whirlpools had stopped whirling; a nearby bee hung suspended over a paka plant, its transparent wings frozen in position for a downward stroke; and the heavy purple fluid overhead held fast in its manufacture of whorls and nimbi. With everything around him in a state of perfect tableau, Purnie hurried toward the ocean. The ocean lay at the ready, its stilled waves awaiting his command to resume their tidal sweep. Overhead, a flock of spora were frozen in a steep glide, preparatory to a beach landing.
 The ocean is acid.
 The ocean is freshwater.  The ocean is saltwater.  The ocean is purple liquid.  The ocean is acid.
