This is one game that never fails (as yet!). Have two old sleeping bags and two racers. Each racer is put in the sleeping bag head first so that they can’t see where they are going. Ideally only their feet, if anything, will be visible out the end. Set up a starting line and a finishing line. On ‘go’ the ‘caterpillars’ must squirm and wiggle their way to the other end. To add variety and vast amounts of hilarity, set up obstacles like chairs and boxes for them to go over, under, between or around.
First one to the finish line is the winner.
