May decides to prove to her big sisters that having a pony is not just for kids Horses have always been the biggest part of May's life. Her father was a horse trainer and her mom rode too. Even May's best friends, Jasmine and Corey, share her passion for ponies. But ever since May's big sisters moved on to soccer and boys, they think her love of ponies is childish. Can she ever get her sisters to understand? Sometimes she wishes she were an only child like Jasmine and Corey. But when May is chosen to lead the Pony Parade at Pine Hollow Stables, she sees it as a chance to prove that she's not a little kid anymore.
