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?
To collect eggs, build a 2 room pen (Dino gates work great as walls and dividers). Agro a bunch of TBs and lead them to one side of the pen then trap them in. Lead them back and forth between the sides as they drop eggs.
These boys are actually not that bad if you have a sword. As a lower level I was terrified of these guys until one attacked me. I just started backing up and it couldn’t catch me. These guys are actually really slow so just keep backing up and hitting them.
