Miss Amy's ballet studio is putting on a new dance performance called the Butterfly Ball! Performing in a show means lots of practice for Rosa and her four friends. Together, they rehearse leaping, balancing, and twirling to perfect their butterfly dances. But when Rosa's audition goes awry, she is cast in a disappointing role. Soon, Rosa discovers her small role is of great importance, and she feels as beautiful as a butterfly . . . and maybe even more special!
