NCF – Extended list of Neutral creatures.

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