In Bad Mojo, insect scientist Roger Sams has stolen one million dollars.  He plans to run away with it.  Roger's mother, Angelina, died before the game began.  Before leaving with his stolen money, Roger touches a necklace that had been his mother's necklace.  It is a magical necklace and it turns him into a cockroach and drops him in the sewer below the building.  Roger's human body is still upstairs.
