One sunny day, Barbie decided to explore the beach by her house. She loved the ocean.

She saw something shiny in the water. It was a beautiful, colorful tail.

The tail belonged to a mermaid named Marina. She looked sad and needed help.

Marina had lost her magical seashell necklace in the ocean. It gave her special powers.

Barbie offered to help find it. They started searching the ocean, swimming together.

As they searched, they met a friendly dolphin named Dolly who wanted to help too.

Dolly suggested they look near the coral reefs, where shiny things often get stuck.

They dove deeper and saw amazing fish and sea creatures along the way.

Finally, they found the necklace! It was caught between two corals, sparkling brightly.

Marina put on her necklace, and her eyes lit up. Her powers were back!

She thanked Barbie and Dolly and granted them each a wish for their kindness.

Barbie wished for the ocean to always be a happy and safe place for everyone.
