Triple Blast Outdoor Inflatable Splash Pool Backyard Water Slide by Kahuna
As its name suggests, the Kahuna has a large footprint -- with an 11-by-13-foot space, this is not the toy for small yards. But if you've got the space, it's a ton of fun, with three sprinkler-wetted slides, a splash pool, and two basketball goals. It inflates in about two minutes via an included blower.
