Finn climbed to the island's peak using rope and tools. Standing at the summit, he saw the entire island and discovered the problem of ocean pollution. The wind was strong, but the view was so beautiful he forgot his fatigue. Shell said, "The ocean needs our help..." Finn decided to report the findings to Dr. Marina.
The expedition ended. Finn stood on the beach, looking at the blue ocean. Shell solemnly said, "Finn, you are now a true Ocean Guardian. Remember, protecting the ocean is everyone's responsibility." Dr. Marina patted Finn's shoulder, "The discoveries from this expedition will help humans better protect the ocean." Finn watched a sea turtle swim by, filled with hope.
