How do you find out what the sound is in the sewers on my sims agents?

Answer 1

The sound is Brandi mining Destinite crystals on the other side of the wall. To get to her, you have to climb back up to the street, then head to Club Candy (which is up past the junkyard and the Morcucorp truck). Then you go into the club.

When you get into the club, you will see Esma standing in front of a manhole to the left of the stage. If you ask her to move, she will refuse. Then you have to talk to Sapphire, and she will tell you that music can move a person. After that you go over to Esma and discuss music with her; she will make you guess her favorite song. First, ask her if she likes rock and roll, then ask her if she likes "The Scrapbooks," and she will tell her that her favorite song is "Bunny Hill." Once you have this lead, go over to Candy and ask her to queue up Bunny Hill.

There will be an outscene of Candy playing Bunny Hill, and Esma leaving the manhole to dance with Makoto, Zack, and Sapphire. With her gone, you have access to the manhole after the outscene. Climb down to the bottom of the catacombs. Brandi will be there, mining Destinite crystals. You will confront her, and she will run away.
