When Luffy and others came to this island, there was a group of organizations belonging to Caesar Krone. The organization wore a gas jacket, equipped with gas bombs, and its weapons were very advanced, which once put Shan Zhi, Nami and others in crisis.

The new king Shaqi Wuhai Trafalgar Law is also on this island.

There are tea-bearded pirates on the island, foxfire guards, warriors from the mysterious country of peace, and a large group of children abducted from surrounding islands.

Caesar krone used the biochemical research equipment here to carry out many mysterious studies. It seems that he killed many pirates and then frozen their bodies.

Caesar krone has subordinates in the lower half of animals, and he was originally a criminal tested by the government. They all lost their mobility because of leaking urine. Caesar Krone put on remote control balloons for them, and Trafalgar Law put on animal legs for them. The accident was caused by Caesar Krone, but the rescued pirates mistakenly thought Caesar Krone was the savior. In fact, Caesar Krone is the chief culprit in being used as an experiment.

Vice admiral Wihlgaard also landed on the island. He was a spy planted by Dover Langminge in the navy, and took, Luo and heavy smoker into custody as the men of Don Quixote Dover Langminge, the Super Seventh Army, which also confirmed that Dover Langminge was the patron clown behind Caesar Krone's illegal behavior.
