Harper prepares her pony Webster for his first real job—carrying salt to market—hoping it will instill a sense of duty. But Webster, determined to avoid work, fakes a fall into a stream to wash away the salt and lighten his load. When Harper catches on, she swaps the salt for sponges. The next time Webster plays victim, the sponges soak up water, doubling his burden and turning his trick against him. Struggling under the weight, he learns firsthand how deceit leads to harder consequences than honest effort. Humbled, Webster changes his ways, embracing work not just for rewards like oats and playtime, but with growing pride in doing his part. Over time, their weekly trips become a shared success, transforming reluctance into responsibility and strengthening the bond between girl and pony through trust and teamwork.
