The Garbage Worm is a monster found in the utility room off the Parking Garage, attempting to pull Gaston, the building's chief custodian, down by the legs through a hole in the ceiling. You must find a route to the floor above to attempt to help him. Upon entering the room, the worm will pull the janitor fully into its mouth before turning to face you. The ground floor room connected to the worm's room below is the Mailroom's shipping and receiving room, found at the end of the left ground floor hallway, past the elevator. The janitor's keyring is hanging from one of its teeth during the battle. This will fall once the worm has been killed. If the player goes back to the elevator, descends, and returns to the base of the worm after the janitor has been pulled down, they will instead fight the lower body of the worm.
