1001. You ask Phil what you must do to escape with your imagination intact. He replies that if you keep moving down river you will enter a cave. Before you enter, however, you must re-climb the precipice to retrieve a -lantern- for light. Then jump into the river and float into the cave. Once inside, the walls will be covered in drawings and pictures that just beg you to use your imagination. But you mustn't. For if you do, you will use it up. Once you reach a spot in particular, there will be a momentary lack of drawing. This place is the closest to the real world. Once there, imagine a doorway. You must hurry through this quickly. If you don't, you're imagination will be used up, for this is the hardest part to sustain imagination.
