The Captain NPC is an NPC of the game Greed Island. He determines who is able to leave, by boat, from the Island, and sails them to the exit. He can be found on the only port in the game. To get on the boat, one needs a ticket obtained by either bribing him or defeating him in a fight.
His mood seems to change. Depending on how he's feeling, the bribe offered can differ from one day to the next.
