NCF – Extended list of Neutral creatures.

There are two creatures in NCF: the Nungug and the Peri. The idea of adding them to the fifth level of the Academy was good, but despite the fact that both creatures resemble upgraded versions, they don't have an unupgraded version. Could someone create another retexture of the Shaman for similar purposes? Moreover, it wouldn't be superfluous for the NCF mod itself.
