Note: this page is about horse stables, not to be confused with donkey stables.
The stable is green with a locked stall and bags for carrots. However, horses never go into the stall. They eat and sleep in front of the stable.
Each stable costs 10,000 coin and can hold up to three horse. The second stable is unlocked at level 37, the third one at level 40 and the last one at level 47. Building them takes no time.
