Medusa Head

The Medusa Head is the boss from the eight dungeon in The Legend of Zelda: Oracle of Seasons, the Sword and 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 you must jump using the roc's cape and avoid the stun spheres then evade its attack and only then can you strike it with your sword to finish it, or, you can use the hyper slingshot and pegasus seeds to stun it, and attack.
