Eye Eye, Captain!

Captain Cutlass is short-sighted and without his glasses he can't see a thing. His parrot keeps telling him to put them on, but he refuses. Pirates don't wear glasses and if his crew find out they'll make him walk the plank! But, as the pirates set sail for Treasure Island, the Captain is soon in trouble. He mistakes a whale for another pirate ship and shows he can't even read a treasure map. How long will it be before his crew discover the truth? And what will happen when they do?
