In fiction, wild animals rarely act the way that they do in real life. Those hilarious Comic Relief chimpanzees and their hilarious antics? Never once do they get violent, no matter what (they may get mad for the hero's benefit, though). When animals do get mad, they're usually easily calmed down if just given whatever MacGuffin is necessary. Is a bear rampaging through town? Just give it some honey and everything will be OK. Being a Friend to All Living Things can help, but surprisingly often it seems like nearly anyone can calm down a wild animal.
