One night, Don Isidro and his three sons heard a stampede of horses crashing through their gardens. They were shocked to see horses of every color of the rainbow. When they shot at them, the horses fled the garden, leaving the vegetables completely destroyed. Don Isidro ordered his sons to guard the crop during the night. The oldest son failed, the middle son failed, and then it was the youngest son’s turn to guard. He succeeded in capturing one of the horses, which asked him to let it go. “Then I will rescue you when you are in danger,” it said. The youngest son agreed and freed the horse.
