Cookie first appears when Sam Temple is looking for Little Pete with Astrid Ellison. He is sitting with Howard Bassem and Orc, drinking beer together.
When Caine first arrives at Perdido Beach, he arranges a meeting that is held in the church. After speaking for a few minutes, there is supposedly an earthquake (later it was discovered that this was caused by Caine's Power). The 'earthquake' topples a cross inside the church, which lands on Cookie. It splits his shoulder open and shatters all the bones within it. Dahra Baidoo and her boyfriend, Elwood, take care of him until Lana comes and heals him. After this, Cookie becomes faithful to her. His fate after this is unkown, as he is last seen at the end of 'Hunger', and it is possible that he might have been killed in a battle in the last four books.
