At long last, Gilligan's Island has been discovered, off Townsville, identified as Magnetic Island, and supplies are been rushed to the shipwreck survivors who have been marooned there since black and white TV days. Directing the rescue mission is none other than the skipper of SS Minnow, Captain Jonas Grumby , shown sending in a stately Bentley to pick up millionaire Thurston Howell,lll, Mrs Howell and her hats . Rescuers were surprised to find that the group had established a smart thatched establishment with bamboo furniture called Gilligan's Bar , at Arcadia , which serves coffee, meals and freshly squeezed jungle juice .
