Billy is a fan made antagonist in Abandoned:Discovery Island.
Billy is a black and white version of Disembodied with a body with the sailor suit and no longer lacking his hat.
If Disembodied is inside of the office and the player presses the Cactus Kid poster in the office,Disembodied will disappear and change into Billy.
Billy starts at Character Prep 1,then enters the Lounge,and runs to the Office,if the player does not shut off the power quick enough,Billy will stay in the office and permanetly disable shutting off cameras.(for the night)
Whenever Billy moves,a quacking sound will play.
Having Billy and Eustace in the office at the same time will cause a deep laugh to play and then the game will crash.
