This is an interesting one!
Based on the fact that this has only be done once before by someone named Dr Frankenstein creations, and that baby chondro's are hard to hatch, and raise as babies, these crosses should be selling in the neighborhood of $1,500-$2,500 each
The breeder would be wise NOT to sell any though, as future breeding projects with these being bred back to diamonds, jungle carpets, and again back to Chondro's would be the key to even crazier offspring.
Then breeding the future babies to lets say a lone male white sided black ratsnake could introduce an even wider range of genetics to the soup!
