Here is the one I used:
Your house has been spooked during the night
By someone in the neighborhood who wants to give you a fright!
A bag of treats has been left for you
Full of Halloween candy and other goodies too!!
Now it's your turn to give someone a fright,
By placing three bags of candy & ghosts during the moonlight!
You have only one night to spread your ghosts,
So the whole neighborhood will be haunted the most!
You will need to make 3 bags of treats to take to 3 houses on the street!
You will need to place a copy of this rhyme in each goody bag you leave,
So the next house will know how to proceed!
Once your house has been spooked, leave your ghost on the door,
So that we will come no more!
HAPPY HALLOWEEN!!!!!!!!!!!!
