During the search for Sarah Peterson's doll, the boys received information that the doll may be kept by Bill and Fosse in the McDonald residence. Upon arrival, they find the duo playing gynecologists on the doll, attempting to "operate on her vagina", later tying the doll up on a chair. As the boys were outside negotiating with the duo, a group of FBI kids led by Agent Tucker interferes with the boys' mission, ordering them to leave. Instead, the boys decided to go through the back door and play gunfight with Bill and Fosse, reclaiming possession of the doll.
The residence is a single-floor house with an attic and attached garage to the right, painted green in a similar shade to the Broflovski Residence. Inside the house, only the living room and the kitchen were shown. Some furniture appear partially worn.
