This little one is made for an italian RPG book, called Eden: The Deceit ^^
It will be soon published in the USA as well
Quite an interesting story it has ^^
The Hydra in this system is quite an interesting fella ^^ It has an ooze like body, similar to a pseudopodia, it grows heads out of it, with sharp teeth and a never ending hunger. The more they eat, the bigger they are. If a head is cut, another hydra will form from it that can multiple heads on its own
Oh, and if you do manage to destroy it, the annoying thing’s parts will morph into a larva and will consume anything, once they get swallowed from the inside. Lovely, isn’t it ?
