I had less extreme versions on some other black, blue, and chestnut himi. Breeding sallander and frosty/ermines I had a lot of black based chinchilla or sable with both agouti and self versions that were all nonextension and the sables I started with caused himi to end up in the mix. Some just look like they might have a hidden broken gene with markings missing on the feet and others only the tips of ears or toes are faded while some are nearly nonexistent like Rhi. I don't know if a chocolate base (chocolate, lilac, lynx...) would be any different.
