Biwwy

 is a 9-year old child in Little Lamplight in 2277.

Background
Biwwy, or Billy, is a young boy with a slight speech impediment, making it hard for him to pronounce the L and R sounds. He used to be on the scavenging team in Little Lamplight, but was kicked out of it because none of the other kids could stand him. Now he walks around the alcoves of the Great Chamber alone, playing with his Wazer Wifle.

Relationships
Biwwy (or Billy) doesn't seem to have any friends, as everyone finds him annoying, possibly because of his speaking disabilities and apparent hyperactive nature.

Other interactions
Biwwy (or Billy) wields a unique Laser Rifle called the "Wazer Wifle" which can be bought from him, or if you have the Child at Heart perk can be obtained for free.

Appearances
appears only in Fallout 3.
