All animals and animal lovers are welcome at the Animal Ark Veterinary Clinic. At Animal Ark, Mandy Hope helps her parents treat animals of all shapes and sizes. Even outside the clinic, Mandy can't resist helping any animal in need. Mandy is thrilled when her dad wins first prize in the Christmas raffle. He's going to own a racehorse for a day! Bright Spark is the most beautiful thoroughbred that Mandy and James have ever seen. But he is famous for hating the rain, and the forecast for race day is looking gloomy. Will he overcome his fears and win?
