Oh crap. I'm sorry, I forgot to put that detail in the description, Yeah it's actually really complicated, you need to smite an underwater erupted area to actually get grass and seaweed to grow, but you need to quake in deep water to make a volcanic fault, the grass is actually made by the creatures made from doing the above, I was thinking of how to make sense of the whole thing, or simplify it, while also making it feel like a discovery, but I'll admit I didn't quite get as much time to work on this as I thought I would have...
