Rolley Wratchetbolt III roams the streets to escort folk home should they need assistance. He is the 3rd of his make (the first 2 unfortunately exploded the moment they were wound-up by their inventor, Professor Douglas T. Ringleberry) and takes his job very seriously. Many an unlucky thug, who has tried to accost one of Rolley's charges, has discovered very quickly that he is not a steam-bot to be trifled with. The unfortunate louts are heard to tell tale of Rolley's catchprase: "And that, good sir, is how I roll."
A steampunk style wind up rolling robot. He wears a green top hat with a light-bulb 'flower' stuck in the brim.
