To develop self rally skills. The person makes a foghorn sound while juggle volleying or juggling groundstrokes. Rocks are scattered throughout the court area in front of the lighthouse. Players chosen as rocks are to sit on the court facing away from the net and are to make a swishing sound while juggle volleying or centering the ball.
Boats are players walking backwards from the baseline to the net.
While walking backwards, boats are to juggle groundstrokes. Rocks are capable of sinking boats that either come too close to them or crash against them. Boats that come too close can be tagged by a rock, at which time the two players exchange roles. The first boat to make it to the lighthouse without crashing or sinking wins.
