Ballet Cat and Sparkles the Pony are trying to decide what to play today. Nothing that Sparkles suggests--making crafts, playing checkers, and selling lemonade--goes well with the leaping, spinning, and twirling that Ballet Cat likes to do. When Sparkles's leaps, spins, and twirls seem halfhearted, Ballet Cat asks him what's wrong. Sparkles doesn't want to say. He has a secret that Ballet Cat won't want to hear. What Sparkles doesn't know is that Ballet Cat has a secret of her own, a totally secret secret. Once their secrets are shared, will their friendship end, or be stronger than ever?
