Flashbacks

A group of anthropomorphic animals, including a fox in a pilot's helmet and a pig in goggles, stand in a desolate, rocky landscape as a small bird dangles from a rope above them; the bird swings back and forth, its tail feathers flapping, while the animals remain still, observing it. The scene then cuts to a black-and-white, grainy war sequence showing soldiers advancing across a battlefield littered with debris and smoke, with figures moving forward through the haze.
