Ko-Wahi is the region of ice on the island of Mata Nui.
Ko-Wahi is the fourth area that the player will encounter. The goal is to find the Turaga (Nuju), to find the Koli Statue (a hovering red statue resembling a bucket), and to find the exit to the level. The only real new enemy is the Patrol Warrior, but there are new hazards, such as ice, which slides the player to the left or right, often into sharp ice spikes. The level is divided into two parts.
