The Gray Horse was introduced as part of the Horse Stable on 3 February 2010. When a farmer completes their Horse Stable they are given a free gray horse, which can be found in their gift box. It can also be awarded from the completion of a neighbor stable. It is most likely based off the real world gray American Quarter Horse. When placed in the Horse Stable, the Gray Horse takes 1 day to Grow vs the 3 days outside the Horse Stable. On April 10th, 2011, the Gray Horse could be offered as a limited time gift.
