Everyone sits round the edge of the parachute. One player is chosen by the leader to start the game.

That player is the Mouse. The player gets up and goes round the circle tapping each person in turn on the shoulder and says “Mouse” as they do this

However as they pass one person, as they tap them, they say “Cat” and run round the circle back to their seat, while the person now labelled as CAT chases after them. The Cat then becomes the Mouse and the game is repeated.
