The Candy Factory (おかし工場, Okashi Kōjō?) is a new addition to Fishman Island. It was built to appease their new protector, Yonkou Big Mam (Charlotte Linlin). It produces "Sweet Candy" for the Yonkou. In order for Fishman Island to remain protected by Big Mam, a large amount of Sweet Candy must be paid to her every month.[1] The factory is ovular, with four pillars built into it for support. The overall base resembles that of a coliseum. On top of the base, there is a dome with a large spire protruding at the top. There are several smoke stacks coming out of the base. The end of each smoke stack resembles a barrel. Big Mam's jolly roger is advertised on the side of it. The factory first appeared in Chapter 610.
