Pewku

Pewku was Orkahm's favorite ussal crab in Metru Nui. When she went to Mata Nui, Onepu took her. She later was handed over to Takua, and helped him and Jaller find the 7th Toa.

Owner
When Takua became a Toa, fans speculated her fate. Some say she went to Jaller. But Jaller became a Toa Inika, so it is assumed that she went back to Onepu.
