Walk to the back of the demon and talk to him. He will turn his back to the dwarf and the dwarf will do his thing.
Coneman - Talk to the voodoo demons first at the voodoo circle. Get the red and yellow pool ball from the pool table by removing the cat in there. Win the doll using the yellow pool ball. Give the red pool ball to the kid and get teeth. Then bring both to the voodoo demons. Then acupuncturist.
Good luck!
