Jack was a boy who lived with his widowed mother. Every Saturday he and his mother would go to the market. Jack would spend his allowance at the book store. He was collecting the volumes of the Book of Mayhem.
As Jack made his way through the market, he noticed a robot dog in the electrical equipment stall. He struck up a conversation with the dog, and they became friends. The dog was slowly being sold for parts. Jack would visit him every Saturday.
A few weeks later, Jack finally obtained the last volune of the Book of Mayhem. That same day, all that was left of the dog was its brain. Jack took the brain home with him. (PROSE: Kept Safe and Sound)
