Players line up in a queue, each with their own ball.
The first player starts dribbling, and the others follow at the same pace.
The coach can shout "snake's tail changes!", at which point the last player in the queue moves to the front.
The coach can specify different styles of ball dribbling, e.g. using soles of feet, only with one foot, etc.
The snake must stay together without players colliding with each other!
