Yeah, but something that completely seal coats the stomach lining that prevents the absorbing of water and nutrients 😏 and it doesn't have to be something permanent like the super glue route, just something that continuously brings them within an inch of their lives. Like it coats the stomach for like 2 or 3 days before it goes away, but add the additive to whatever their favorite foods are so that they eventually figure it out and have to eat all the foods they hate. Then when they acquire a taste for that food, out the additive into that as well and go back and forth for the lulz as their mental health deteriorates. That'd be a perfect punishment for (((the tribe)))
