Our Moonlight Double Dip Castle is one of our many Dry Bounce Combos. We use non slip material on the entrance ramp and on the jumping mattress to prevent the kids from slipping. Enter the front of the 13'L x 10'W bouncer, make a left and go up one of the two climbing ladders then down the slide. If you want to use it wet you must purchase it with the detachable pool.
