The King Penguin by Vanessa Roeder
Percival the King Penguin doesn't think he's asking for too much when he makes all the rules - he is a king after all. But he's tired of the other penguins protesting, so he's off to find subjects who are more obedient and supportive. But it won't be the seals. Or the whales. And definitely not the rude sardines. As Percival gets chased away by every new group of potential subjects, he'll have to learn how to put his best flipper forward and live in a community, not a kingdom.
