— A mech wolf talking about the metal[src]
The metal was a large gear. It was a rusty brown color. It was taken from the tavern. According to several Mech Wolves, it added a nice tangy flavor to the fuel. It was used, along with the Wood and Leather, by Bentley to create the Archer Costume for Sly.
