Caterpillar Race

Divide a large group into several teams.  Each team gets a bed sheet.  Have one half of each team go to the opposite side of the room for a relay race.  Hand a bed sheet to the first person in line on one side of the room.  At the word "GO", the first person must drop to the floor on the bed sheet, roll themselves up into a "caterpillar" and then "inchworm" crawl to their teammates across the room.  There they must unroll (the receiving team may assist!) then the next person in line rolls up and inches back to the other side.  Continue the relay until each person has crossed to the other side.  Great fun!
