Hot Head

Hot Head serves as the boss of Turtle Rock in Link's Awakening.

Hot Head resembles giant Podoboo, the living fireballs from the Super Mario series, also encountered in this dungeon. He also resembles Fryguy who was a boss in Super Mario Bros. 2. Hot Head attacks Link to prevent him from playing the Eight Instruments of the Sirens and waking the Wind Fish.

Strategy
In battle, Hot Head jumps out of the lava briefly to shoot fireballs at Link. In order to vanquish it, Link must hit it with blasts from the Magic Rod. After being struck, Hot Head will lose its flames and start bouncing off the walls before returning to the lava to recompose itself. Hot Head is capable of dealing great damange to Link either by making contact with him or by hitting him with splashes of lava. Once it has sustained enough damage, the boss will crack to reveal a smaller head underneath, although its attack patterns will remain the same. Upon its defeat, Link earns himself a Heart Container and the Thunder Drum.

Trivia

 * Hot Head bears a lot of similarity to Gouen, a boss in Four Swords. Hot Head's Japanese name translates to "Big Flame", while Gouen's name can be translated as "Master Flame".
 * It is strange that Hot Head is weak to fire, as he is a flame enemy.
