Absolutely a normal.
It doesn't matter if your friend has no normals, it can still be a normal. Any co dominant morph will produce 50% morph babies and 50% normal babies.
Even if your friend bred a fire to say a mojave, 1 our of 4 babies from that pairing will still statistically be normals.
If you need help with some of the ways to recognize morphs, this site has two excellent morph guides.
But as far as how different normals can be, here are three of mine.

All of these are normals.
