The Island of the Crab 2000 ( 6.2)

A pirate ship called Cain. A treasure hidden inside a stone head in the middle of the ocean. A sea full of sharks. A crab shaped island whose only access is an immense cliff. A pagoda shaped bar. A parrot next door, hanging off the cliff and an immense castle on the rocks. It's Karramarro, Karramarro Island.
