The 40 ft Rainbow Mega Obstacle Course is an eye-catching unit with a physical challenge! The two-piece open-air design structure enables an easy setup. Rainbow archways welcome riders to the obstacle course's starting line, where they must maneuver around a variety of pop-up obstacles. The next stage has riders push through a wall of inflated columns and crawl-through tunnels. Finally, they must race up the climbing wall and slide down. The first racer to reach the end is the winner! Overhead netting is designed to ensure kids' safety. The see-through windows mean others can follow the action easily!
