Ussanui

The Ussanui was a vehicle that the Toa Nuva and Takanuva built so the latter could travel to Mangaia. It used 6 Shadow Kraata for navigation and was built out of the remains of the Rahkshi.

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. Toa Lesovikk took the shattered remains sometime afterward to the Pit, and used it to create his Sea Sled.
