Ussanui

The Ussanui was a vehicle that the Toa Nuva and the new Takanuva built so the latter could travel to Mangaia. It used six Shadow Kraata for navigation and was built out of the remains of the six Rahkshi that terrorized Mata Nui.

Takanuva took it to the lair of Makuta Teridax, with Hahli secretly stowed away. The Ussanui was then destroyed after crashing into a wall near the entrance of the lair. Some time later, Toa Lesovikk took the shattered remains to the Pit, and used it to create his Sea Sled.

Set Info
The Ussanui was released in 2003 as a Titan set, and a Takanuva model was included. It contained six Rahkshi back parts, assorted Bohrok-Kal tool pieces and a grey Hau that was, the at the time deceased, Jaller's.
