Okay, so if you don't know what Plopup are, they are aptly explained in this link here. Plopup are a particular problem, as their speed, durability, regenerative capacity, and shapeshifting abilities allow them to effectively infiltrate human villages, even mimic adventurers, so while they're rare they're also a massive threat.
So, what is the goal medieval people have concerning Plopup? Same as dragons; for most everyone to survive, even if that may mean sacrificing a maiden or two. However, this problem extends beyond Plopup merely eating people. As intelligent, malevolent beings, they want to have their preferred food accessible, in large quantities, and to be protected from harm.
This means Plopup tend to seek positions of wealth and power (as this makes them "untouchable") and/or isolation. I realized a particularly scary scenario thanks to the answer to this question, namely that Plopup could steal money, use it to obtain orphans, and then raise them into a veritable army of fanatically loyal followers that they can use for food.
Even worse, there is the possibility of a Plopup using their abilities (and powers of persuasion) to become a religious leader, even pose as a divine entity (such as a demigod).
So, the problem? Medieval people must defend themselves from Plopup. However, in order to do so, they must recognize the threat. So my question is, How Can Medieval People Defend Themselves Against Plopup? Specifically, against Plopup eating them, conquering them, etcetera, etcetera.
- I understand complete protection against Plopup may not be possible, so instead I am asking for the optimum defense strategy, one that medieval Europeans can both come up with and actually execute. This strategy could range from the typical MDS (Medieval Dragon Safety) strategy, namely sacrificing maidens to the monster, or to simply create a secure perimeter and let nothing from the outside in at all costs.
2. The best answer will list the worst Plopup scenarios (ie. potential threats) and come up with strategies that fit the specifications in #1 to deal with them. These worst scenarios would be: 1, a Plopup gaining a position of power and/or great influence, 2, a Plopup successfully posing as a divine entity (similar to but distinct), and 3, if possible, a strategy to prevent Plopup turning orphans into fanatic followers. Why? I know 3 will be hard to stop, but if a Plopup accomplishes it, it will also be enabled to evolve into a Bloatup, making it even closer to invincible.
Good luck, and thanks for your input!
