About the Thriller Bark Arc
During their journey through the Florian Triangle, the Straw Hats arrive on a seemingly haunted island called Thriller Bark, where they encounter the Warlord Gecko Moria. Using his Devil Fruit abilities, Moria steals the Straw Hats' shadows. With the help of a mysterious talking skeleton named Brook, the crew must regain their shadows before sunrise in order to survive.
A few days after their departure from Water 7, the Straw Hats enjoy the features of their new ship; Usopp and Luffy go fishing together and toss everything they catch into the aquarium, while Robin, Franky and Sanji relax in the dining room, Nami takes a bath in the bath hut, Chopper enjoys his expanded room/infirmary and Zoro takes a nap in the observation tower.
When Zoro wakes up, he notices a barrel floating in the ocean and alerts the rest of the crew over the built-in speaker system. When they fish the barrel out of the sea, they notice that it is an offering to the sea god. After a short discussion, they open the barrel, but instead of finding food and sake, a red light shoots out of the barrel and into the sky. Fearing that someone may spot them and knowing that a big storm is heading in their direction, Nami orders the crew to head southwest. Unfortunately, the headwind catches them, prompting Franky to unveil the Soldier Dock Channel 0; a set of paddle wheels. Using the paddle wheels, they avoid the storm and finally enter the Florian Triangle.
At first, Usopp thinks they might already have arrived at Fish-Man Island, but he is quickly corrected by the others who explain to him (in a teasing manner) that they are in fact in the Florian Triangle (he did not know this, since he was not around when Kokoro told the others about it). Upset that he was not notified about this and scared about the ghosts, he quickly grabs his exorcism set to rebuke any evil spirits. Suddenly, he and the rest of the crew hear an ominous song resounding throughout the fog and discover a ghost ship that has suddenly appeared behind them with a skeleton singing Binks' Sake.
