Sabaody Archipelago

Shabondy Archipelago is a chain of islands close to the Red Line. It is home to many kidnapping gangs such as the Flying Fish Riders. The headquarters of this particular gang is five kilometers east from Grove 44 of the southeastern island of the archipelago.

They are,in fact,a set of mangrove trees,which have no magnetic pull.

Pappug explains that the trees produce a special resin, which is blown into bubbles when the trees "breathe out" (it can be inferred he means when they release gas through cellular respiration/photosynthesis)

Around the Shabondy Archipelago there are "coating mechanics" who cover ships in the special resin mentioned above. It is this resin that allows ships to go underwater to fish-man island.

There are about 79 trees on the islands.

World Nobles are sometimes seen going around the place.
