The story I heard on the chocolates goes like this (2nd and 3rd hand info so take it with a grain of salt):
Strictly Reptiles hatched them (two in 2002 I think) from cinnamon pastel like parents so it appears that they might be the homozygous/super form of a co-dominant cinnamon like (not sure if it's the same as Graziani's cinnamon pastel) co-dominant mutation.
They have a lot of odd things like missing nose scales, which may or may not go with the mutation.
In captivity? I think only two like mentioned above (considering I had never even heard of them before this) but in the wild? The possibilities are endless.
I have a pic of a black ball beside another ball,but i cant remember where i got it.
I am not sure how to post pics from my hard drive,but if someone wants it i can send it to you.
