Can Marlon the merpig, star of every show, still find a way to shine when he's cast as seaweed in the school play?

Every year, Marlon's school puts on a show, and he is always the star. That is, until his teacher casts him as—gasp!—seaweed in the new production. But after getting over the shock and then trying unsuccessfully to convince his teacher that seaweed should have a solo, Marlon realizes he can make himself known in a different way this time. His friends need his help to ensure that the show is spectacular, and he's just the merpig for the job!

This funny undersea story about learning to be a team player is as exuberant as Marlon the merpig himself.
