Within Nyaltojo, there’s a Water Treatment Plant that attempts to restore water to a drinkable state. Within these same waters, the dangerous Pokemon known as Toxipus reigns supreme!

'Conversation efforts across Tamago are at an all time high recently after the discovery of a Pokemon that actively produces a toxic sludge into water streams in order to leave its prey sluggish and sick, so it has a much easier time in capturing and eating it. That Pokemon is Toxipus- at this moment, there currently exists over 300 of them within the 80-gallon drum situated within the Nyaltojo Water Treatment Plant.

I've personally raised one of these Pokemon, and frankly, I'm unsure how to proceed in their existence. Not only do the evolutions of Toxipus become MORE dangerous, they become unwieldy and stubborn; sometimes, they'll do things just for the sake of doing them, with the final evolution outright ignoring me if it wishes to do something else.

Still, as a Pokemon Professor, it's hard to determine whether or not these Pokemon are unredeemable- I feel as though, with time, these Pokemon will begin to evolve for the better, like many other Pokemon that exist outside of the Tamago Region. It's just a case of figuring out whether or not that'll be within time before their existence becomes too dangerous to keep around…'
