Maniac Mansion Cheats

Hidden key

Take these two items to the second floor, to the room with a piano and TV. Once there, put the record on the victrola and the cassette into the tape recorder. Turn on the recorder, and then the victrola. Wait until the vase on the piano breaks before turning off the tape recorder. Once the tape is made take it down to the living room and put it in tape deck of the old-fashioned radio. Play the tape. The high frequency will shatter the windows and then the chandelier. And the key will fall onto the floor!
