Kaukau

"Mask of Water Breathing; big help when there's no water anywhere around."

- Gali, BIONICLE Legends 10: Swamp of Secrets

The Kanohi Kaukau is the Mask of Water Breathing, sometimes called the Mask of Water. It gives its user the power to breath water and only water for a limited amount of time. It also only let its user breathe water down to a certain depth.

Kaukau were carved out of a mixture of Shrink, Regeneration and Remove Poison Kanoka on Metru Nui.
