Burglars
In A Link to the Past, there are burglars in the game that can steal rupees, bombs and arrows from Link whenever they touch him. In addition, they do not cause harm. When they glance at you they will chase you until you are a considerable distance distance away. They can be found in a human-imp shape in the Lost Woods and in the Village of Outcasts with a fox-like form. You can stun them with your sword or a long range item (such the boomerang) for a short time, but unfortunately they are virtually invincible.
