What is better for birthday events than a giant inflatable birthday cake? This commercial grade bounce house looks just like a birthday cake, right down to the inflatable candles that decorate each exterior corner. Crafted from tough commercial vinyl material in bright red, deep blue, and vibrant yellow, they are built tough for years of play. This model comes in two sizes. The smaller has a interior, and the larger has a interior play area. Each side features a large mesh-covered opening.
