I've seen all of those!

Just idiosyncrasies, I guess. (although the raindancing makes sense, if you think about it hard enough lol)
What are idiosyncrasies? By the way even if all my villagers raindance(there are 105 of them) they will never make rain! That's good, though, because in VV3 when it rains, the villagers all run for cover and forget about their job.
