Bob-omb

Bob-ombs are living, moving mechanical bombs with eyes, feet, and a wind-up key in the back. In most versions of any Mario game, they are blue or black and see you as the enemy. Some versions depict particular bob-ombs as allies (usually indicated by their pink or red color). In my opinion, they are the most tastefully used enemy in Super Mario World (they are dropped in from the sky and parachute to the ground). They may not be smart; but, they are deadly!
