Their heads were the most foolish-looking things you ever saw, and they balanced on the ends of their tails in deep water when they weren’t grazing, bowing solemnly to each other and waving their front flippers as a fat man waves his arm.

“Ahem!” said Kotick. “Good sport, gentlemen?” The big things answered by bowing and waving their flippers like the Frog Footman. When they began feeding again Kotick saw that their upper lip was split into two pieces that they could twitch apart about a foot and bring together again with a whole bushel of seaweed between the splits. They tucked the stuff into their mouths and chumped solemnly.
