Babusu

The Babusu is an enemy found in The Legend of Zelda: A Link to the Past. They are small hole-dwellers that run across the room. Babusus resemble little black tadpoles with legs, and are first seen in the Ice Palace. They are found in holes at the bottoms north side of the wall, and make a silver sparkle before exiting to run across the room to a hole on the opposite side. These creatures can be easily defeated with a strike of Link's sword.
