The upper Tunnel will be blocked on the outside with large stones by the Womracquets who will then enlarge this tunnel into a living area. The animals will burrow into the ceiling and create sleeping quarters that are the same size as themselves. When the animals wish to sleep, they jump into their quarters and dig their claws into the earth, so they can’t slip out. If a predator found their burrow, the place would look empty as all the Womracquets would be hidden in the ceiling.
