The dossier says:
"Found only in the dark caves of the island"
They are already wrong! It should say something more like:
"Found everywhere but the dark caves of the island, this creature will gladly ruin your day by jumping out and killing you as soon as you even think about going to the swamp. Nearly impossible to tame because it has to be tamed via passive which is very difficult to do. Worst of all you need to feed them fertilized eggs. Why can't it e a little easier? Up-vote of you agree!
Very Simple Rule Of Thumb, DO NOT LET THE GLORIFIED ANACONDA HIT YOU. This pretty much renders you snake food. Escape is not easy, as even after you’re long outta range they still follow for a while before becoming disinterested. If they catch up while you don’t expect it, they kill yah, simple as that. In this situation, on a server, just run, and run, and run, and run, and run, until you find another players base, preferably with some kind of spike wall and hide behind that until the snake either runs off, or dies from the spikes, then go home, build your own spike wall (wood works just fine) and try to repair them every time they break.
