A news report takes place outside the Circlovich residence, where it was reported that Billy needs $600 for a bone marrow operation. While Billy's condition was genuine, the news report itself turns out to be fake, a trap set up by the American Dental Association (ADA).
When the boys head down to Billy's house, Kyle (who had earlier questioned his existence) vanishes, before being intercepted by Loogie and his gang, and subsequently the ADA themselves. Kyle, however, re-appears and began to alter reality, scaring off the police, the ADA and most of Loogie's gang. While Billy manages to get hold of the $600, Loogie decides to end his tooth racket business.
The house is colored pale green, and is built similar to every other house in South Park, with a detached garage.
Billy's bedroom is situated on the lower floor, at the right side of the house.
