The Wihta

This is a legendary species from the most ancient past of Karda Nui.

Known to be very wise as it ages, it can go over all sorts of terrain. Yes, even the swampy areas. How? Its back feet have air pockets. So, by lifting its front legs like so-

-it has unlimited access to all of Karda Nui's floor.

The Wihta, proving to be nuisance to the Makuta, were hunted down, and eliminated.
