 * Talk to Billy - He will inform the player that he had fled to the fridge when the Great War started and that he had been trapped in the fridge for two hundred years. He tells the player that he wants to find his family and return to his home in Quincy.
 * Escort Billy to his house or sell him - You can either choose to help him get there or sell him to a member of the Gunners named Bullet for caps. His house is not far, but there are a few gunners between you and the house.
 * Ending - If you choose to help him get to the house you will find his parents survived the war and are happy to see him. Bullet and some other Gunners will arrive shortly thereafter and demand Billy and his parents step outside. If you choose to fight Bullet, Billy's father will give you 250 caps for saving them.

Behind the scenes
This quest is a reference to South Park season 7 episode 11 "Casa Bonita" in which Cartman convinces Butters that the world has ended and locks Butters in an abandoned refrigerator at an old gas station for Butters' protection. Billy will also say many of Butters' lines while in the fridge, such as: "it's really dark in here" and "There's no handle on the inside" etc.
