A Spiked Head is one of the many enemies in the Game Boy Advance game, Wario Land 4. Unlike most of the enemies in the game, a Spiked Head is immune to most of Wario's attacks. However, it can be defeated by some of Wario's forms. If Wario touches the spikes surrounding a Spiked Head, he will lose health. Their unique appearance resembles a round, greenish creature with a face, with spikes surrounding the facial area, hence the name "Spiked Head". They can be found in the Ruby Passage, mainly in the level The Toxic Landfill. They are also found in some Puzzle Rooms, where they are used to act as a barrier to stop Wario from accessing some places.
