Located in front of the building, MonstroCity features two Sabreliner 40 aircraft fuselages suspended high in the air, a fire engine, a castle turret, a 25 feet cupola, four-foot-wide Slinkies that can be crawled through, one very high that leads to a slide, and two ball pits, one for young children and one for older ones, each pit being filled with large, rubber dodge balls.
