code from room three (95616) is zip code for davis, california. he gets sad+mad alot in room 4 as you destroy objects. i think the repeating sentences that come up when you type "joey" might mean something in java. a book called 'computering' in the study talks about 5-letter codes for security
hmm, in room 4, with pit you can drop the lunchbox and matches in the pit by taking them and then USE "item" PIT. Also, if you use the kite then drop it, it hits the ceiling, breaks and falls in the pit. If you do any of these, the master starts threatening you.
