As Bob likes to wander the world, he has one of the largest wander radius of all NPCs in the game, spawning in his human Unferth's house in Burthorpe every time there is a system update, but after which he is able to wander anywhere that is not restricted by physical boundaries, being able to wander to far away places such as Varrock and Port Sarim. It is possible to locate Bob by using the Amulet of Catspeak after it is enchanted in A Tail of Two Cats which, when operated, will open a menu that looks like a cat's face: Bob can be found in the direction that the white coloured dial is pointing.
