Caves, dungeons and any dark place.
Small black bat creatures as you have them in MC.
These are bat like creatures that like dark places. They are not particularly strong or though to defeat. Their strength lies in numbers as they there is always more than one Keese in a room.
They move around from one spot to the next in a bit of an irregular pattern. The never really fly in a straight line. Except when really close to the player, they will make a straight line towards him, before continuing to the destination spot. There they will sit still for a while and start the pattern again. Defeating: Just hit them with any weapon you have, even the boomerang kills them.
