Break up the boredom of summer and challenge your friends to an adventure. It s time to play ball—underwater—with the Banzai Melon Madness Pool Challenge. This water-filled Melon Madness ball has just enough buoyancy to dribble, pass and catch underwater. Unlike your basic beach ball, turn any backyard pool game into grab-and-splash football or an underwater basketball challenge. The included hoops are weighted to stay put below the water s surface to create the perfect target for any game. Hose adapter and filling needle are included for fast and easy assembly.
