Well if you don’t know what the green book is then you aren’t ready for the ending. But since we’re such good people we will explain everything right now. When you bring back the final red/blue page one of the brothers will tell you to go to the book in the library on the middle shelf and to the right. Look at the diagram #158. Write that down then go in the chimney and press the red button and copy that diagram onto the screen in front of you. Then pull the red switch and you will turn around and there will be a red page a blue page and a green book. THAT IS THE GREEN BOOK!!!!
