How Little Sister joined the Tourney
ADAM is excreted by a Sea Slug found near Rapture. However, the sea slug did not naturally produce ADAM in large enough quantities for serious research and exploitation. Brigid Tenenbaum developed a procedure whereby a sea slug was implanted in a host's stomach. After the host fed, inducing regurgitation yielded up to thirty times the amount of usable ADAM. Female children, known as Little Sisters after implantation, were found to be the only viable hosts on a technical and biological level. Although Tenenbaum hoped to keep the children in a vegetative state, they had to be fully functional in order to produce ADAM. They still maintained many of the ordinary characteristics of children: laughing, playing, smiling, and singing.
