Sabaody Archipelago, also known as the Soap Bubble Islands, is situated right beneath the Red Line in the middle of the Grand Line.
The entire island is made up of seventy-nine Sabaody mangroves, with towns and various facilities built upon each tree.
The natural resin secreted by the roots of these mangroves through respiration expands in the air to form bubbles, and bubble culture permeates every corner of the island.
