“They called him Flipper, Flipper, faster than lightning…” But Hammerhead is a baddie and sharks aren’t supposed to be baddies any more. Sharks are friends, not threats. So Hammerhead slipped quietly into the distance to await his time of glory, when one day he will return to rule the Ocean with an iron fist head.

Incidentally, dolphins have had a troubled role-reversal in the fashion of popular opinion too. They were friends! Companions! Even amusements for a while, before everyone agreed they should be free. Now they are wanton rapists and bullies. Shed a tear for the poor, maligned dolphin, carrying the disgrace of his ill-behaved friends and relations. All Dolphins Are Not Bad.

One day the Bottlenose and the Hammerhead will return as friends, splendorous and loved. But will they find the World worthy of their love? Or will they leave, with a parting farewell, and a thanks for all the fish.
