Iwao (岩男) is an enemy which appears in Wario Land 4.
Behavior
These tough, pudgy creatures attack by throwing large rocks at Wario. Iwaos are also invulnerable to most of Wario's attacks, and they can only be defeated by Ground Pounding onto them.
In Wario Land 4
Iwaos only appear in Fiery Cavern. Here, when Wario jumps on the switch in the level and the temperature radically changes, the Iwaos become Yetis which implies that these enemies change with the climate.
