Hahnah

A hahnah crab was a crab-like Rahi that inhabited the Pit. One member of the species was attracted to the heat and light produced by Toa Mahri Jaller's sword during the Toa Mahri's escape from the undersea caves the Barraki put the Toa in. Ever since then, it followed him. Upon seeing it, Jaller wondered if he had seen Toa Mata Tahu the same way when he had first arrived on Mata Nui.

Behind the Sets
On the Toa Mahri Jaller set, the hahnah crab was included and could be attached by a chain to his Cordak Blaster.
