Poopsie Pomerantz is sure that ballet lessons will make her slim and graceful. But her friend Tracy Matson makes fun of Poopsie's efforts, saying there's no hope for chubby Poopsie. Tracy is surprised when Poopsie announces she's getting the starring role in her dance school's ballet. And Poopsie's surprised, too, because it's not true! She didn't mean to say that. Now she has to pray that Tracy doesn't come to the ballet, because guess which part Poopsie really has?
