Granted, but you must climb mount Everest, fly to London with a jetpack, drink a cup of tea, teleport yourself to New York city, then make at least 5 new friends while there. Then, you must sleep for 5 hours EXACTLY, and that sleep must be on a bed made out of twigs and leaves. Then, you must win 1 million pound. Then, go to turnback cave, and it should be sitting there, on the top of a pillar which you must climb. To do this, go out and buy a ladder, and some safety equipment. You should get to a ledge on the pillar, of you approach from the right side. You will then be teleported to the top of the pillar, but the Muller corner strawberry flavour yoghurt will be poisoned :(
I wish I could think up loads more things like that ^
