The Walk the Plank turns an exciting Sky Trail® experience into an exhilarating one! Guests are encouraged to walk out and face their fear high above the ground. In addition to creating an exciting element on its own operators often add a rope the guest has to grab to activate a special experience. At Nickelodeon Universe® in the Mall of America® guests can activate a fog horn on the Sponge Bob-themed course. This element also offers a great spot to capture pictures using a photo system.
