- Health: Cannot be harmed
- Damage: Infinite (Instant Kill on touching side or bottom while moving)
- Size: Huge (4x4)
- Corpse?: No
- Stunnable?: No
- Special: Jumps and hovers briefly before landing. If the spelunker is underneath it during the hover, it will smash down. This destroys blocks underneath it, and causes clusters of yellow energy to shoot from its gem that transform into enemies when they hit the floor.
The Giant Head is very similar to the final boss of Super Mario Bros. 3. It cannot be damaged, and touching anywhere on it while it's moving will cause you to die. There is one safe spot on the boss - that being the very top of the head. Standing there will allow you to reach the treasure in the upper parts of the level without use of a rope.
The only way to kill it is to destroy the floor underneath it and force it to jump in the lava, which will kill it. This is possible to do simply by running underneath it, but is much easier with bombs or Sticky Bombs.
Be forewarned: killing the Head only causes a door to appear at the far right side of the level. You still need to get to it in order to win the game; be sure you have some means of getting out of the pit the boss digs.
The key element in this fight is to remember to have a place to go when Olmec jumps, aside from under him.
