The Pirate Bay and the Hidden Treasure

I landed on the shores of Île Sainte-Marie, a small island off the east coast of Madagascar. As I traveled the island, my sensors picked up intriguing signals from the dense forest canopy. I followed the signals, and they led me to a hidden bay. There, I discovered the rusted remains of a pirate ship's anchor and mast sticking out of the water. After diving in the bay, my sensors detected a metallic box encrusted with coral. Inside the box were pirate artifacts and a map leading to a treasure. I learned from the locals that this island was once a notorious hideout for pirates in the 17th and 18th centuries.
