Moon Bounce Philadelphia, Philadelphia

Not only does Moon Bounce Philadelphia deck out parties with more than 20 rainbow-colored inflatables, it also delivers peace of mind. Each of its bounce houses, water slides, obstacle courses, and combo units is registered with the state through the Department of Agriculture and cleaned before anyone sets foot on it. Large or toddler-size bounce houses meet the antigravity needs of a traditional birthday celebration, whereas specialty inflatables such as the pirate-ship combo unit—complete with a faux crow's nest—complement themed parties and train Navy recruits.

Interactive inflatables such as the basketball-shot model sharpen the aim of sports buffs, and a wet-dry slide safely catches fast-moving riders with a bumper wall. The 40-foot Ninja Jump obstacle course, meanwhile, challenges kids and adults to maneuver around horizontal and vertical pop-ups, through tunnels, and over rock walls to reach the end.
