Mermaid School:
the Clamshell Show
Lucy CourtenaySheena Dempsey

Marnie Blue has settled into Lady Sealia Foam's Mermaid School and become best friends with Pearl and Orla. And now might be her chance to shine - the Clamshell Show is coming! Marnie and Orla are both auditioning for the star role, while Pearl (who is no great singer) is sticking to playing the rock tuba. But a new mermaid wins the role, and at rehearsal she's more trouble than a tiger shark with a toothache. What's more, Mermaid Lagoon has an unwelcome visitor dropping by. Will the show go on?
