I like Kappas. Read a lot of kwaidan and ghost stories as a kid like I was a prepper memorising rules for the monsterpocalypse or something and kappas always struck me as so goofy and cute, like they have this divit in their head that has water in it that gives them energy, but if you bow respectfully to them, they will reciprocate and spill the water from their heads and become lethargic. Also they apparently really like cucumbers (who doesn’t) so people will toss them into waterways to placate them.
