When you are in the Castle of Daventry, enable the give birthday suit code and go to the locked gate at the front of the castle. There will be two guards in front of it, so you cannot walk right up to it. Use the bump code about eight or nine times to pass through the guards and the locked gate. You will now be outside the castle. Every thing will be gray, dark red, and dark blue. You can even see the water fall from which you entered the Castle. Do not walk on to the gray sections. Although you will not fall to your death, you will just fall forever and have to quit your game. When you can see the waterfall, walk as far up to it as you can on the ground, and then walk off the gray. You will not fall this time-- instead, you will be able to walk on air.
