Roxie was Zachary's seeing-eye dog, a German Shepherd. She became separated from him after the bus was pulled into a gulf in the street, defending him from a monster. She can be found in the bottom right corner of the Sewers. She will not trust a stranger, but if asked, Zachary will give Sam Roxie's Chew Toy, which can be shown to her to win her trust. The Sewer Beast, the former bus driver for the students, is in the room with Roxie, and must be defeated to leave.
