At the top is Ginna in the process of shooting dirt out at a mad pace to get to some unknown target.
Middle photo is of Pesca in the giant hole they all dug. She is able to go in and turn around. She hides from the others when the frisbee is coming her way.
Bottom photo is of Vando. Ginna has the frisbee.
Occasionally John fills in the holes so they get to start all over again. Having this space keeps them from digging all over the yard.
