'Skin the Snake'

Girls line up in teams, one behind the other, legs apart.

With their right hand they hold the left hand of the girl in front and with their left hand they hold the right hand of the girl behind (still with me?) obviously the front and back girls only hold one hand.

Then when you shout 'go' the back girl has to crawl through the tunnel of legs, without letting go hands taking the other girls with her until the girl who started at the front ends up at the back.
