Bin is your digital pet. You have to take care of him: clean, feed (by using trash files), tell him good words. Make Bin happy to get rewards! Otherwise it might be a nightmare. He has sentences like: I'm afraid of ProgressDOS very much! It's so dark down there!, I wonder why the sky on Progressbar95's intro is blue?, Who is better: Clippy or me?, Why are the files made of zeros and ones?.
