Melody is a maid who cleans in The Lab. She was created by a scientist named Professor, and she works for him. Melody must be wound up with the winding-key on her back or she will shut down. Melody is depressed, and she knows it. She is quite sarcastic and often uses dry humor to make her life less boring. She is not human, she is more of an organic robot created by the Professor. When wound up all the way she can operate for about 12 hours.
