this happened on my 4th village
i was trying to double up kids on a turtle shell, very near the waterfall.
when i dropped the second kid, instead of a shell, he came up with a pan of water and it said 'taking it to the fire pit'.
well, i checked and the fire had 8+ hours left.
out of curiosity, I was wondering if the fire could be put out, i picked up several more kids and put them by the waterfall.
sure nuff, they picked up pans and headed for the fire.
after about 5 kids, the fire was out and there was the gem!!
i just didn't know you could do that!
