Derrick Derrick – A two-headed brass lizard. It was about the size of a sneaker and was created for the sake of finding and fetching small components like loose screws. It got a little too ambitions though; the canny bastard would sneak out and eat whatever tiny screws and bolts it found unsupervised, spitting them back up on Fisher's desk.
After it raided Derrick's room once (or twelve times) too often, she reprogrammed it to recognize Derrick as an "owner" like her. The good news is that it then stopped stealing from Derrick. The bad news is that it started stealing for Derrick.
