After spawning on the "Goat Ville" map, look towards the cornfields. A dirt track is to the left and the goat ring is to the right. It is a red ring with people cheering around it. Step in the ring and a goat will be summoned each round. Push them out any way possible. Do not allow your opponent to headbutt you. If you cannot headbutt or kick them out, knock them down and lick them to drag them near the edge of the ring. Be careful not to walk out of the perimiter yourself. Each time you win a round, your goat gets slightly larger. Defeat four goats to earn this achievement.
