Farkas believes living in a haunted house has made him sick, but he doesn't know what to do about it. Suddenly, in walks Madame Mumu, who startles Farkas because he didn't hear the doorbell ring. She claims she tried ringing the doorbell, but nothing happened. At that point, a lizard moans about the doorbell not working, tells Mumu to go outside, then heads over to another room, where he alerts a dozing group of musicians (a Gamelan ensamble) that someone's at the door. The group then makes an elaborate doorbell noise with their wooden xylophones, so that Mumu can make a proper entrance. She introduces herself to Farkas as a ghost exterminator, which piques his interest. Mimi and the two fish spot Farkas again, and try to cheer him up with another bouncy piece of music. Mumu dances merrily
