Sometime after we got the Going Merry, we started keeping a list of what we all thought the One Piece actually is. All entries were either put down as both serious and jokes. A few friends from other crews would add their hot takes later on.
The following things that have been theorized to be the One Piece (serious and not) (no I will not confirm if the actual One Piece is on it):
A literal mountain of treasure accumulated by Gold Roger - common belief
Zoro’s sense of direction - self explanatory
Sanji's left shoe - he threw it overboard accidentally one time. It had been meant for a pirate and he panicked bc we were caught off guard (for once he adamantly insists). It had not been recovered in time. We joked that it would find the One Piece before we do. Nami has an active betting pool for it.
Buggy's family heritage - so everyone could finally learn which side of the family he got his nose from. Rayleigh jokingly said it was probably from Roger since the man was a slut and it wasn't until his late 30s that he finally grew into his big ass nose.
Luffy’s common sense - if this has to be explained, then you need to go back and watch the anime again
The Land of Forgotten Toys - I had one too many drinks (bc I mistakenly drank a bunch of fruity drinks that I didn't realize had alcohol. Again.) And decided to tell stories, which included a bunch of Christmas stories. Luffy was both awed and sad about the weird toys and wanted to find them to recruit them to the crew. I didn't have the heart to tell them it wasn't real.
Law's coin collection - bc that bitch Teach destroyed his ship and despite best efforts much of the Heart Pirates's personal belongings were lost at sea, including both Law's coin collection and his Sora Warrior of the Sea collection and merch. Law personally added this to our list, while cursing Teach's name every way that he could.
Doflamingo's conscience - no one is sure who put this up. The night in question it had been added is a blur for everyone.
Crocodile's missing hand - Sanji added it at the request of Iva. Crocodile was not amused.
A poneglyph that explains the reason all of these existed and the world's real history before the World Govenrments takeover which led to the rewriting and censorship of history - Robin, but only bc she wanted a real, serious entry to hide among the silly ones. Don't worry, she actually helped argue in favor for eveything else that was added. She’s very convincing when she's an active participant in coverations/debates.
A rainbow bridge that leads to the moon.
Enel - bc he went to the moon on his weird gold ship, conquered it, then found the Rainbow bridge and stays there. Luffy hopes its true so he could kick his ass again and that we'll hopefully know how to extract Devil fruits bc I made the bad suggestion of saying that Nami should totally get his DF bc she'd go from Weather Witch (I call her this after Alabasta) to Sky Sorceress (I start calling her this after she gets Zeus) to Thunder Goddess. Nami is still on the fence about it, but us DF users have been slowly winning her over (Luffy has just been chanting "one of us" at her whenever the conversationcomes up again).
The jackass that kidnapped our precious flower Iris from her world and graciously gifted (read: lost) to us - Sanji put this up and asked that I make sure to write it out word for word. He mostly hopes that what brought me here is an actual person so that I could nut-punch them since that's what I've been saying that I would do whenever someone asks me what my goal is. There is apparently a long list of people who would like to be present when this happens bc they have some choice words. This list includes: the Strawhats, Heart Pirates, Kidd Pirates, Crocodile, Doflamingo (don't ask, I don't want him there), Shanks, Buggy, numerous Navy admirals and officers (probably to curse this individual for bringing such a headache to their world), Vivi, Perospero (bc he didn't like it when I called him a man-child), Judge (you'll figure it out one day), Caesar (to complain), and a bunch others idc to add (Iva: how rude!!)
The ancient Kingdom - Lilith added this one on behalf of all the Vegapunks.
Candy Mountain - I introduced Bonney to Charlie the Unicorn videos I had saved to my hard drive and Kuma hasn't forgiven me since (Iris: I'm sorry, Kuma!!! Kuma: *sitting there listening to Bonney quote Charlie the Unicorn videos and smiles* I forgive you (he actually does not))
