The Animal Rescue Dolls are excited about their trip to the Wild Isle to check on the wild mountain ponies. But when they reach the clifftop, they find a yearling, trapped on a cliff edge. Just as they're about to bring it to safety, it's startled by a gull, and taking fright, runs down the narrow cliff path to a cove far below. But the tide is coming in and the Dolls will have to tempt the pony across the water to safety...
