Kaukau

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

- Gali, BIONICLE Legends 10: Swamp of Secrets

The Kanohi Kaukau was the Mask of Water Breathing, sometimes called the Mask of Water. It gave its user the power to breathe underwater, albeit only to a certain depth and for a limited amount of time.

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

Set information
The Kaukau was first released in 2001 in transparent blue with Gali's set, and was also available in transparent red, green, black, white and (curiously) orange as one of the two randomly-selected Kanohi in the supplementary Kanohi mask pack.

In 2002, the Kaukau was also released in a similar Mask Pack, this time in gold or silver and also coming with three Krana in addition to the other randomly-selected Kanohi.

The transparent blue Kaukau later returned in 2003, as part of the Hahli Matoran set.

Trivia

 * Before the Bohrok destroyed it, Naho Falls had a massive Kaukau statue carved into it.
 * This mask is not related to Turaga Matau's Kau Kau Staff.
