Fifty colorful balls come in the box and the 61 x 44.5 in splash pool doubles as the pit for them, which extends the use of the park into dry weather. A 370W blower is included - modest wattage matched to a modest 142.5 x 77 x 76 in castle rather than the giant parks that need 700W. The jumping area measures 58.5 x 56.5 in and the slide 38 x 19 in with a 4.7 in handrail. It suits ages 3 to 12, 100 lbs per child and 200 lbs in total, weighing 33 lbs. Stakes, hose kit, repair kit and carrying bag are supplied.
