Pearl has always dreamed of being famous: the star-studded stage, the sea flowers, the applause! So when she finds out that her third grade class is performing The Little Human, she just knows she'll get the leading role. Especially since world-renowned merstar Angelfish Molie is judging the tryouts!

But in a shocking turn of events, Pearl's best friend, Wanda, gets cast as the little human instead...and Pearl is stuck playing the stinky sea witch. Pearl can't believe her best friend would steal her dream role from her.

After Pearl tries--and fails--to get Wanda to trade parts, she decides to quit the play. Are Pearl's dreams of being a sea star doomed? And can she and Wanda patch up their friendship before it goes up in bubbles?
