Underwater Magic - The Secret Mermaid

Secret Mermaid Molly must help her mermaid friend Delphi to find the second piece of the enchanted conch shell in time to prevent a terrible oil spill. Unfortunately, Delphi's shell is guarded by a spiky sea urchin, and the only way they can tempt it away is by bringing it some treasure from a spooky shipwreck, where a great white shark lurks.
