In the Stone Age 2.

Neanderthals cross their territory hunting a mammoth. Once a friendly mammoth notices the danger, she joins in the fight making the Neanderthals flee in turn. As the mammoths take chase, more Neanderthals join in the hunt and turn away the mammoths. As both groups grow in numbers, the sabretooth tigers take this opportunity to try and catch some easy prey. The mammoths and the Neanderthals must now both run away from the danger.
