Be nice? Yes, let's be nice. What is NOT nice is hormonally or surgically mutilating children, cheating your way to stealing women's athletic medals, lying your way into women's spaces, debauching language etc.
The penguin is out of his nature, he's done swimming. He's got a fishing rod. He's taken up smoking cigars. He's not happy anymore. Sometimes he thinks about swimming around but ever since the hernia he doesn't want to take that chance. His wife wants to leave him, he doesn't care. He's been reading the Unabomber manifesto and starting to wonder if fishing rods are really going to make anybody happier or if we'll just all fall deeper into the sunken place. He's been tinkering with saltpeter in his ice cabin developing a primitive gunpowder that could help his family finally gain the upper hand on their polar bear ravenous seal tormenters, but he feels like he's making no progress. Sometimes he slams his flipper in rage against the table, cursing the flightless wings that God has forsaken him with.
But he is a survivor. So he just keeps fishing. And he just caught one.
