Fox and rabbit

This is our new game! Everyone pairs up and hold hands. One person in the group is the fox and other is the rabbit. The fox must try and tag the rabbit. The rabbit runs away but can get into a "burrow" which is in between a pair arms. If the rabbit goes into a burrow, whoever he/she has its back to is the new rabbit who must run away. If the fox can tag the rabbit, the rabbit then becomes the fox and the new rabbit must run away.
