Gather all the cousins and bring them to the snowy island. Release them and press "A" to make a snowball. Throw it with "A" at a cousin, then dodge when they retaliate. If the snowball hits another cousin, they will also try to hit you. If you keep dodging, they will keep throwing snowballs until either you are hit or nobody is hit.
