Idea: add a new creature to the game, Sharks. Specifically, Greenland Sharks. They could be roughly as hard to kill as a boar, maybe the parasites on their eyes could be a curio, and then you kill one and butcher it for shark meat!
One problem, though: Greenland Shark meat is poisonous, at least before it's been processed into hakarl.
How do you make hakarl? You start by beheading and gutting the shark, burying it in a gravel pit for six to twelve weeks, then cutting it into strips and hanging the strips to dry for a few months.
Chef Anthony Bourdain describes it as the single worst, most disgusting and terrible thing he has ever eaten! Gordon Ramsay was once offered hakarl, and immediately spit it out!
IDK, seems like a good fit for this game. Maybe instead of giving FEPs, hakarl should reduce your hunger, presumably by making your Hearthling throw up.
