Monster Truck 4n1 Combo with DRY Slide. This 4-feature challenge is jam-packed with fun, offering a generous area of jumping area, basketball hoop, climb and slide. Take a look the video to see a real life video of the inside. Big bouncing area with the slide built inside the bounce house. This bounce house is great for keeping the kids all in one spot. No worries of them sliding out and not going back in. They also take a few trips down the slide and the kids get a great laugh. We also have a 7n1 Combo with the same Monster Truck theme.
