At his shoulders two broad, feathery wings expanded, and these enabled the monster to cleave his way through the water with terrific force.
Zog was part man, part beast, part fish, part fowl, and part reptile.

His undulating body was broad and thin and like the body of an eel.

It was as repulsive as one could well imagine, and no wonder Zog hated it and kept it covered with his robe.

Now, with his horned head and its glowing eyes thrust forward, wings flapping from his shoulders and his eely body--ending in a fish's tail--wriggling far behind him, this strange and evil creature was a thing of terror even to the sea dwellers, who were accustomed to remarkable sights.
The mermaids, the sailor and the child, one after another looking back as they swam toward liberty and safety, saw the monster coming and shuddered with uncontrollable fear.

They were drawing nearer to the dome by this time, yet it was still some distance away.
