Okay, I must be dumb.

I've been playing for a while, got the beehive, the lift, three trees in the orchard, the chief, levels 2 in alchemy and restoration, level 1 in nature.

I keep seeing people say that there's a way to make it rain "any time you want."

Well... how? I've tried the things I could think of, like the happy feet potion, dancing at the fire, chief dancing at the fire... nothing worked so far.

So... how?
