Thank You all for your replies. I tried several different options before posting.

bethlham - Key was as you stated...receiving message about them feeling springy after drinking potion.

Not sure if there is more to this or not. but wanted to share my solution. I had a master scientist brew potion & drink. The first time he drank he was unsuccessful in reaching the gem. I went back and drank some more and that is when I received villager feeling springy. Also had stars over his head not under his feet like the weather dance.

Again THANK YOU ALL for your replies!!!!
