Thriller Bark

Inspired by Nessos and Rob Gucci, it cements something else I've suspected: counting among the various refugees looking for asylum in Wano were probably Hippo Men, Reptilic races, Shellfish-based Fishmen...those racial outliers who've found themselves on the lowest link of the food chain in their respective societies, or at least placed in a very awkward position given their races' diets.

Just think about it. Kinda hard being a Crocodile or Hippo Man living in Mokomo Kingdom when people are either trying to eat you or an animal that looks like you. Same with say being a Crab Man over on Fishman Island. Some like Hachi may see no issue with eating Takoyaki, but I'd expect not everyone might feel the same way.

I bet if one were to trace the evolution of One Piece's civilizations of anthropomorphic wildlife, it'd reveal a numerable series of social contracts centered on what ( or whom ) it was acceptable to eat, with increasingly restrictive menu options arising throughout their history. In the beginning, it was probably sheer chaos, where the typical predator/prey dynamic played out much as it did in nature.

But thanks to their higher mental faculties, society among the Minks, Fishmen, etc. would begin to take shape, with tribes forming along same species lines, then predator and prey, and so on...Intermingling would naturally occur....and soon enough an entire nation would form around the concept of a unifying, shared trait that would classify them as one respective. One slight problem tho...
