Think about it.
>Riko spends a good portion of the village arc with diarrhea from consuming somsthing weird
>when Riko lies on the ground to pantomime "I want an inn" there is poop next to her and she almost lays in it
>Riko goes out of her way to hydrate because, incidentally, Jiruo told her that diarrhea kills Cave Raiders through dehydration
And then we get the mockwater flashback about the ganja squad. It puts diarrhea on the brain and then uses diarrhea as a major plot element. Foreshadowing, and subtle foreshadowing disguised as a goonerbait gag.
Also, the eating-babies thing was foreshadowed by the weird half-developed writhing egg larvae they eat after escaping the Iron Rain. Remember how they ate those eggs with fetuses still inside? That was foreshadowing Irumyuui's babies.
