Ep 526. Undersea Volcanic Eruption! Drifting to the Fish-Man Island!

As the Straw Hat crew sails towards the Fish-Man Island, they encounter a massive volcanic eruption that puts them in danger. The episode opens with Luffy and his crew on their ship, the Thousand Sunny. Suddenly, they notice a strange cloud of smoke in the distance. Upon closer inspection, they realize it's coming from a nearby underwater volcano that has just erupted.

As they try to navigate around the dangerous area, they encounter a group of sea creatures who are also trying to escape the eruption. Among them is a young mermaid named Shirley, who predicts that Luffy will destroy Fish-Man Island in the future. The crew doesn't take her seriously at first, but they soon realize that there may be more to her prophecy than they initially thought.

As they continue to sail through the chaotic waters, the crew comes across a group of pirates who are also trying to escape the volcano. One of them turns out to be Caribou, a former enemy of the Straw Hats who they had left stranded on an island months earlier. He begs them for help and promises to be their ally if they rescue him.

The crew reluctantly agrees to save Caribou, but they soon come to regret it when they realize that he is still up to his old tricks. He tries to steal their treasure and sabotage their ship, but the crew is able to stop him before he can cause any real damage.

Eventually, the crew makes it through the volcano and arrives at Fish-Man Island. There, they encounter a group of powerful Fish-Man warriors who challenge them to a fight. However, they quickly realize that the real enemy they will have to face is not the Fish-Men, but an even greater threat that lies in wait beneath the ocean's surface.

Overall, this episode is full of action, suspense, and surprises. The crew faces numerous challenges as they navigate through the volcanic waters, and they are constantly on guard as they encounter new allies and enemies along the way. Fans of One Piece will no doubt enjoy this installment of the series, which sets the stage for even more epic adventures to come.
