A webcomic storyboard in four panels, black and white and sketchy:
Panel 1: A cute mermaid sings, eyes closed, with a melancholy expression, sitting on a rock in the middle of the ocean. She plays a small lyre.
Panel 2: Aerial view: many boats gather, forming a circle around the mermaid, drawn in by her performance.
Panel 3: The mermaid bows modestly to the enthusiastic applause of the sailors on the boats, who give her a standing ovation.
Mermaid: Thank you...
Panel 4. The mermaid now yell angrily to the sailors. In the foreground little fish, crab, and shark are throwing trash back to the boats.
Mermaid: "...And now that I've got your attention, stop polluting our waters and take your trash with you!"
