When they finally reach Skull Island, they have the misfortune of bumping into Greybeard and his band of cutthroat pirates once more, who mistakenly believe that Steve and Alex had stolen the fabled Ghost Island treasure. The pirates turn on them and only with Jedrick's help and fast thinking, are they able to outwit the pirates and finally journey to the mainland to go and find and rescue Marial.
But between them and the mainland, a giant and deadly monstrous sea creature known as the Kraken lies in wait in the treacherous depths of the ocean. Will Greybeard's ship the Jolly Roger be able to survive the Kraken's attack at sea or will the ship go down, taking all onboard with her?
