You go in the building on SLUDGE STREET, you talk to the MOUSE. Go to where the mouse tells you, talk to the FISHERMAN, get the letter--M--, and go to the next person on MAIN STREET. he is READING a newspaper. Talk to him, get the letter, go to the next person who he tells you to, the letter is A. He tells you to go back on Sludge Street, then talk to the man holding a STERO. He tells you the last letter, it's S. The code for the Red Ruby Key on MOSHIMONSTERS.COM is MAS.
