Spiky

Harimen (ハリメン, meaning "needle face") are enemies in Wario Land 4 that can be found in levels of different passages. They appear as yellow heads with red feet that wear pink spiked shells, resembling Spinies. Their shell hurts Wario on contact and prevents them from his Jump and Dash Attacks as well as the Ground Pound. There is also no way to grab them. Their weak point is their unprotected underside. The most common way to defeat the Harimen is by doing a Ground Pound at any place when they are seen, causing them to flip over and to be stunned for a few seconds. Another Ground Pound directly on their underside will defeat them, rewarding Wario with a big silver Coin.

Harimen flip over when Wario touches their underside as well. When another enemy is thrown at them, they are defeated immediately. They can also be caused to flip over by pushing them against a wall, which can be safely done when Wario is invincible, for example as Flaming Wario. As most enemies, Harimen are also defeated when Wario simply touches them during a certain transformation, such as Zombie Wario or Fat Wario.

A sub-species known as Harimenzetto exists as well, which features a black shell and is harder to defeat.
