They came from Odd-looking Hets.
Do you ever seen a green Hog with red pattern?
or
a light-green one, with dark-green pattern which are black borderd?
I saw them last friday, when we put them in the boxes for their winter cool down.
The origin Hets seems to have so much possibilitys. Compared with pictures from other "Normals" they appear very dark.
In my opinion they must have a lot of color-coats.
