Caterpillar Race....Have your kids form teams (At least two) and form a straight line. In between each player is a balloon and they must get to the finish line without dropping their balloon. They can only keep their balloons from dropping by using their chest and the other players back. If a balloon drops, then the team must stop and pick it back up.
Our kids went to a Halloween party last week and this is one of the games they played. There was a spider web on the floor, made with tape. The spiders were made out of egg carton cups, with chenille stick legs, and googley eyes. The spiders were spread out around the web.
