Yeti

Yetis are enemies in Wario Land 4 that appear in Fiery Cavern and 40 Below Fridge. They are pudgy ape-like creatures with white fur and runny noses. Yetis normally move back and forth, but when Wario comes near, they stop and sneeze an icy breath at him that moves horizontally. When hit, Wario becomes Frozen Wario. Yetis can be defeated by any of Wario's attacks and can be grabbed and thrown as well when they are stunned; however, Wario moves slower while carrying a Yeti. For defeating a Yeti, Wario is rewarded with a Bronze Coin. Unlike other enemies that cause a special status, a defeated Yeti does not respawn when Wario re-enters a room.

In the level Fiery Cavern, it is shown that they are related to Iwao, since the latter creatures will become Yetis when Wario jumps on the switch and the temperature radically changes.
