There comes a time when pirates may have to cross the Florian Triangle to get to Fishman island, as they do not have an easy access route like the marines. It is covered in a fog so thick that it blocks out all sunlight. Because of this, many pirate ships go missing every year. Due to this mystery it is also been said that there are many haunted ships with dead bodies sailing across the sea. It is currently the only sea that has to be passed in order to go in or out of Thriller Bark.
