I wonder where Wadatsumi will go since he was banished from Fishman island.
I don't think that Fishman Pirates will return to the island… not even Homies obeys their master's orders, much less them xD
Big Mom must have one hell off a lifespan to be able to keep Zeus and Prometheus for so long. Maybe she is part giant. They have the second greatest life exceptency of this world.
Lin Lin has been wearing Napoleon more than 20 years, time doesn't matter to Homies. What matters is the body safety and scary moments, which can kill them.
Also, i suppose that lifetime doesn't matter to create them, so she can just give them 1 minute of life to generate them, this is just a guess from me.
