Here's the perfect way to have it your way, right away. We start with a castle, a slide, and an obstacle course all of which can be used individually. To kick it up a notch, any two of these units can be combined together to create a combo, be it castle and slide, castle and obstacle, or slide and obstacle - the choice is yours. The ultimate is to combine all 3 units into 1 fun filled piece that will entertain your kids for hours. The smiles and laughter from entering the obstacle course that allows children to enter right into the castle that also allows easy entry right onto the slide. What more can kids ask for. It's different and quite fun!!
