Become an Ninja Warrior and conquer the Inflatable Ninja Wall! The Ninja Wall is an inflatable warped wall with 3 different deck heights. Run up the specially designed warped wall which is firm even though it is 100% inflatable. Non slip vinyl ensures you have enough grip to make it to the top! If you need a helping hand there are removable PVC grab bars to pull yourself up onto the deck; once at the top its a left turn to slide down back to the start.
