The Straw Hat Pirates get sucked into a big drain hole in the middle of the ocean and at the bottom find a mysterious island known as the “Ocean’s Navel” that is being destroyed by giant monsters.
They explore the place and resolve to find the island’s treasure, which can supposedly grant any wish, but the island’s inhabitants possess agendas of their own for their new guests. They help the people living there, fight the monsters, and find a way to get back out.
