BigMouth Giant SprinklerGINORMOUS YARD SPRINKLER! It's the missing piece to that epic birthday, pool party, BBQ, or family reunion you've been planning (or dreading). We made it super simple to use, too. Just inflate it, and connect a standard garden hose. Turn on the water and voila! water sprays out of this dino's snout in a pterrific conical pattern. The inflatable design also means that it's lightweight, easy to move, and deflates for compact storage in the off season.
