Hot Head

Hot Head is the Nightmare of Turtle Rock, the eight and final dungeon in The Legend of Zelda: Link's Awakening. It is a disembodied head cloaked in fire.

Strategy
Nothing very hard. Upon entering the Nightmare's room, just use the Magic Rod like crazy when he appears from the lava pit. Once his fiery cloak disappears, keep shooting at it, and Hot Head will eventually be defeated. Cross the lava pit to retrieve the final Instrument, the Thunder Drum.
