Pirate's parrot

In the far-off Caribbean archipelago, Captain One-Eye's pirate ship, Arabella, was lurking for passengers. A parrot named Herbert always sat on the captain's shoulder. In the fateful sea battle, Captain One-Eye met his end, and Herbert flew away from the scene as fast as his wings could carry him. He took with him One-Eye's secret: where is the massive pirate treasure buried? Herbert the bird might be the only one who knows the location of the treasure, but despite attempts, he has refused to reveal the secret of the treasure. Herbert is indeed proud, mysterious, and very partial to anything shiny... Can you win over Herbert and uncover the secret of the treasure?
