NO details?
How could you do that to me!?

Is it maybe.. a PastelxBlackback?
Some very un-noticable morphs do that, I know. Fires, Vanillas, Blackbacks, Sulphers, and even Spotnoses are just a few examples of some morphs that will make excellent crosses.
LOL - sorry - he is a pastel. Mom is a bb normal. Dad doesn't have a real pronounced bb, but he threw 3 more bb pastels in another clutch that just hatched last week (the 2nd clutches' mom is not a bb).
