At Järvzoo Zoo in Sweden, a goat has found an unusual way to entertain itself. In its enclosure, the animal plays with a ball suspended from a rope, but not in the usual way.

The goat has developed a real technique: it traps the ball with one of its horns, steps back to tighten the rope, then suddenly releases the ball. The ball then swings in front of it, allowing it to give it a powerful headbutt.

Most surprisingly, the goat repeats the same sequence over and over again.
