Crazy Idea…
All because of a party and some tainted wine…
Many of the attendees at a Monkey D. family party get a false positive on a pregnancy test…
Now, how would everyone react?
Extra I: Imu was at the party… Mu has been sick for a few weeks… Mu will put a bounty on the Pregnancy Devil Fruit. Forget the Human-Human Fruit, Model: Nika; it's already been dethroned as the most wanted Devil Fruit by the World Government.
Extra II: Rocks is staring into space, trying to figure out who the father of her "pregnant" child is.
Extra III: Sanji is in shock, on the verge of collapse. Chopper just told him that he's apparently "pregnant"… around that time. He only remembers waking up drunk next to some moss.
Extra IV: Nami is calculating the debt someone will have to pay. She's not having a child for free!
Extra V: Crocodile is keeping Dragon company while he vomits in the bathroom. The good thing is that this time, the job of having the baby didn't fall on him.
Extra VI: Somewhere along the Grand Line, an old woman, known for selling fertility potions, feels her life is in danger.
Extra VII: Elsewhere along the Grand Line, the owner of a liquor company is scolding the new employee for making a mistake in the warehouse! He ended up mistaking some discarded barrels for some in good condition! And as it turns out, some of the defective ones have already been sold!
So like, nobody is actually pregnant, just thinking they are because they had liquor that went off? Also, this probably is the last Monkey D. family party that Imu visits. Spending time around the Strawhat just to trigger some Joyboy flashbacks isn't worth the aftermath.
(Maybe Imu is actually pregnant, it would serve him right. :P)
