Rent this Sports bounce house with or without the slide attached. In the slide attached mode, we call it the combo. This is the perfect bounce house for the little ones that want something more than just a boxed bounce house. However, if space is a problem the sports bounce house alone is a great choice. The sports bounce house with slide (combo) can be used as a wet slide combo. See our "Water Attractions" category for more information.
