Get ready, because Cowgirl Kate and her horse, Cocoa, are back for more adventures on the range. These two best friends love to spend time together - they just don't always see eye to eye. When Kate decides it's time for Cocoa to get new horseshoes, her favorite horse has other ideas. And Kate might have to get sneaky to convince Cocoa to get new footwear. Then, while riding the range counting the cows, they notice a calf is missing. Perhaps he's playing hide and seek, which is just what Cocoa wants to do anyway! Kate also practices her roping skills - on Cocoa. Finally, the two even go swimming. But Kate isn't quite ready to make the giant leap into the farm's pond. This charming follow-up to the Theodor Seuss Geisel Award winner Cowgirl Kate and Cocoa is a hit with kids, parents, and critics. Partners offers children valuable lessons about friendship.
