Kahu

Kahu were huge bird Rahi that were part of the Gukko family of Rahi. Gukko birds were extremely swift, and generally peaceful though they would fight if threatened. Le-Matoran often tamed Gukko for their Gukko Force. Rahaga Kualus insisted that "Gukko" was the incorrect name for the species, and may even have been an insult in their language. A bright green energy filled a Kahu's wings when it flew.

Set information
The Kahu could be made with the two Nui-Jaga. Not to be confused with the smaller Goko-Kahu which was released in the Masterbuilder set.
