Medusa Head

The Medusa Head (or Medelock) is the boss from the eight dungeon in The Legend of Zelda: Oracle of Seasons, the Sword & Shield Maze. As the name says it is a Medusa head; it will stand in the center of the room and throw some spheres that can stun you, then she will perform an attack.

To defeat it requires one of two strategies. Either:
 * 1) Jump using the Roc's Cape and avoid the stun spheres, then evade its attack. Only then can you strike it with your sword to finish it, or
 * 2) Use the Hyper Slingshot and Pegasus Seeds to stun it, then attack.
