I know but with the first 3 villages I have gotten it with only 7 or 8 villagers.(way too early for my liking) Before the last child was even able to work!
So I figured I would try something different in the 4rth village.
I have no algae, crops and now level one in everything except farming. So now with only 8 villagers I still have all my coconuts untouched for if I get the algae!
