Neat little guy; reminds me of one of my favorite normal girls. Might be worth dinking around with, especially if you put aside a female normal just for that purpose.

My brief mental list of "stuff that could be mistaken for a normal if not produced by a reputable breeder" includes:

Special
Specter
Low-quality desert
Low-quality Enchi
Vanilla
Low-quality fire
Mocha
Vin Russo het BEL
Orange dream
Low-quality mystic/phantom
Low-quality calico
Chocolate
Sable
Low-quality axanthic

... I'm not sure if I would include yellowbelly only because it seems that their belly markers are so distinct, there really isn't much question, even if the pattern looks pretty much dead normal ...

I put "low-quality" in front of a number of those because IMO, a high-quality specimen would be unmistakable, but I've seen poor-quality specimens that do look an awful lot like normals.

... Any I missed?
