Use a stencil or cookie cutter shaped like a pumpkin and trace pumpkins on construction paper so that you have one pumpkin for each guest. Cut them out. Write the word ”TREAT” on one of the pumpkins.
On the remaining pumpkins write “TRICK” and a silly thing to do like walk like a spider, or cackle like a witch, or flap your wings like a bat, dance like a fairy, walk like Frankenstein and more.
Now put all the pumpkins in a plastic witch kettle and have each guest draw one out. If they get the TREAT then let them choose a treat out of another bucket or award them a prize. If they get the TRICK they have to do what it says before they can get their treat.
