The Mukau (a.k.a. Mata Nui Cow) was a species of bovine Rahi that lived around Po-Wahi. Their natural habitat was on Mata Nui, and they were a very peaceful species of Rahi. It is possible that they were related to the Mahi.
- Mukau was created by BZPower member Swiftone in 2002.
- Its name is humourously pronounced "MOO-cow."
