This is a variation of duck-duck-goose called "ghost-ghost-witch." Choose one child to be the "witch" and have the rest of the children sit facing each other in a circle. The witch will then go around the circle, saying ghost-ghost -ghost.......witch. Then the witch has to chase the ghost, and if she catches the ghost before he or she gets back to the empty spot in the circle, the witch can put a spell on that child (make him sing, dance, bark, etc.). That child then becomes the new witch and the first witch sits down as a ghost. For little ones, you can be the witch and let them all be ghosts.
